Description: A good quality molded plastic part is one that can be molded with high yield and performs flawlessly in its intended application. To this end there are certain best practices to be adhered to by the part designer as well as the toolmaker/molder. In the preliminary stages of part design there is great advantage to leveraging the knowledge and experience of the engineering team of the toolmaker/molder who have likely “seen it all”. This is in contrast to designing in a silo and passing down design features that need costly modifications after mold trials. It is just as easy to design a part feature that will mold well, as it is to design a bad feature that will hamper molding, eg. insufficient draft angle. To do justice to a well designed part, there are also best practices for the toolmaker/molder to adhere to. Here are 30 best practices to get good quality molded plastic parts.

Description: Plastic parts, with their capability for complex shapes, find many structural applications in many high-end industries like aircraft, automotive, and medical. FEA is a very useful tool to predict their structural performance in complicated applications. However, several critical considerations are mandatory if one seeks accurate predictions of stress, displacement, force, etc. This is because plastics do not behave like metals, for which FEA was originally developed for. This webinar will demonstrate the advantages of those critical considerations versus the traditional linear approach.

Description: Creep failure of plastic parts is the permanent deformation of the part in the presence of stress, time, and temperature. Plastics are more prone to creep failure than metals. Because creep failure only manifests itself after time has passed it is usually the customer who experiences it. This has the potential for costly recalls, returns, rework, warranty claims, loss of reputation, etc. And the correction will take a long time to implement because it likely involves a redesign, re-tool and mold, re-test, which prolongs the customer’s pain. Merely replacing the failed part with one of the same vintage will repeat the pain. This webinar will discuss how to identify potential creep failure of plastic parts, and how to design around them.

Description: Fatigue failure of molded plastic parts is the breakage of the part after repeated application of a load (whether a force load or a displacement load) that induced stresses on the parts. The induced stress at which fatigue failure occurs is significantly lower than the Yield Strength of the material. Plastics are more prone to fatigue failure than metals. Just as with creep failure, fatigue failure only manifests itself after time has passed and it is usually the customer who experiences it. This has the potential for costly recalls, returns, rework, scrap, warranty claims, loss of revenue, legal liabilities, etc. And the correction will take a long time to implement because it likely involves a redesign, re-tool and mold, re-test, which prolongs the customer’s pain. Merely replacing the failed part with one of the same vintage will repeat the pain. This webinar will describe and discuss: • What are fatigue failures, along with some examples. • How to identify fatigue failures. • How did fatigue failures happen? • How to design around fatigue failures.

Description: Control of moisture content in the resin is essential for producing quality plastic parts. This is especially so for hygroscopic resins (ABS, nylon, polycarbonate, PET, etc), yet it is an often-overlooked step of the injection molding process. Excess moisture in the resin can show up as splay (or silver streaks) or may manifest itself later as brittle broken parts. The former can be visually caught and rejected, but the latter may make their way into the customer’s hands. And both will hit the bottom line of reduced profits. Moisture control starts with properly drying the resins, but the only real step that matters is the measurement of the moisture content after drying. And this is where many molders are lacking. This KnowHow Webinar will present the defects caused by excessive moisture, the proper steps of drying, cases from industry demonstrating the real missteps of controlling moisture content, and case studies of real defects.

Description: Warpage of a molded plastic part comes down to uneven shrinkage of the part while it is cooling down to room temperature after ejection. Warpage results in a part that is not of the intended shape, and is one of the most common failures. Understanding the causes for the uneven shrinkage is complicated but it is essential. Those causes are material, design, mould, and processing. Using a jig to hold the shape of the part during cooling, after ejection, is not recommended as it can have disastrous results later. This webinar will discuss the various causes of uneven shrinkage and how to mitigate them. A case study will be presented to demonstrate the use of Conformal Cooling to reduce warpage.

Description: DFMA = DFM + DFA, respectively Design for Manufacturing, and Design for Assembly. DFM looks at the cost for manufacturing plastic parts individually. DFA looks at the cost of assembling those parts together to make the finished product. Together DFMA is the philosophy of making the parts and products to be lean from the very beginning. This avoids expensive engineering changes later. It also makes for a lower cost, better reliability, and better-quality product. DFMA pulls in the participation of all the relevant departments (internal and external) at the design stage, where 70 to 80% of a product’s total cost is established. The material to be used, the type of manufacturing process, the assembly processes are all defined at the design stage. Without DFMA bad design decisions may be carried over into the mass production stage where costs and risks to start over are very high. This webinar will examine the application of DFMA philosophy to molded plastic parts – how to produce the molded parts productively, and how plastic parts can incorporate many features that ease assembly into the finished product.

Description: A good quality molded plastic part is one that can be molded with high yield and performs flawlessly in its intended application. To this end there are certain best practices to be adhered to by the part designer as well as the toolmaker/molder. In the preliminary stages of part design there is great advantage to leveraging the knowledge and experience of the engineering team of the toolmaker/molder who have likely “seen it all”. This is in contrast to designing in a silo and passing down design features that need costly modifications after mold trials. It is just as easy to design a part feature that will mold well, as it is to design a bad feature that will hamper molding, eg. insufficient draft angle. To do justice to a well designed part, there are also best practices for the toolmaker/molder to adhere to. Here are 30 best practices to get good quality molded plastic parts.

Description: Plastic parts, with their capability for complex shapes, find many structural applications in many high-end industries like aircraft, automotive, and medical. FEA is a very useful tool to predict their structural performance in complicated applications. However, several critical considerations are mandatory if one seeks accurate predictions of stress, displacement, force, etc. This is because plastics do not behave like metals, for which FEA was originally developed for. This webinar will demonstrate the advantages of those critical considerations versus the traditional linear approach.

Description: Creep failure of plastic parts is the permanent deformation of the part in the presence of stress, time, and temperature. Plastics are more prone to creep failure than metals. Because creep failure only manifests itself after time has passed it is usually the customer who experiences it. This has the potential for costly recalls, returns, rework, warranty claims, loss of reputation, etc. And the correction will take a long time to implement because it likely involves a redesign, re-tool and mold, re-test, which prolongs the customer’s pain. Merely replacing the failed part with one of the same vintage will repeat the pain. This webinar will discuss how to identify potential creep failure of plastic parts, and how to design around them.

Description: Fatigue failure of molded plastic parts is the breakage of the part after repeated application of a load (whether a force load or a displacement load) that induced stresses on the parts. The induced stress at which fatigue failure occurs is significantly lower than the Yield Strength of the material. Plastics are more prone to fatigue failure than metals. Just as with creep failure, fatigue failure only manifests itself after time has passed and it is usually the customer who experiences it. This has the potential for costly recalls, returns, rework, scrap, warranty claims, loss of revenue, legal liabilities, etc. And the correction will take a long time to implement because it likely involves a redesign, re-tool and mold, re-test, which prolongs the customer’s pain. Merely replacing the failed part with one of the same vintage will repeat the pain. This webinar will describe and discuss: • What are fatigue failures, along with some examples. • How to identify fatigue failures. • How did fatigue failures happen? • How to design around fatigue failures.

Description: Control of moisture content in the resin is essential for producing quality plastic parts. This is especially so for hygroscopic resins (ABS, nylon, polycarbonate, PET, etc), yet it is an often-overlooked step of the injection molding process. Excess moisture in the resin can show up as splay (or silver streaks) or may manifest itself later as brittle broken parts. The former can be visually caught and rejected, but the latter may make their way into the customer’s hands. And both will hit the bottom line of reduced profits. Moisture control starts with properly drying the resins, but the only real step that matters is the measurement of the moisture content after drying. And this is where many molders are lacking. This KnowHow Webinar will present the defects caused by excessive moisture, the proper steps of drying, cases from industry demonstrating the real missteps of controlling moisture content, and case studies of real defects.

Description: Warpage of a molded plastic part comes down to uneven shrinkage of the part while it is cooling down to room temperature after ejection. Warpage results in a part that is not of the intended shape, and is one of the most common failures. Understanding the causes for the uneven shrinkage is complicated but it is essential. Those causes are material, design, mould, and processing. Using a jig to hold the shape of the part during cooling, after ejection, is not recommended as it can have disastrous results later. This webinar will discuss the various causes of uneven shrinkage and how to mitigate them. A case study will be presented to demonstrate the use of Conformal Cooling to reduce warpage.

Description: DFMA = DFM + DFA, respectively Design for Manufacturing, and Design for Assembly. DFM looks at the cost for manufacturing plastic parts individually. DFA looks at the cost of assembling those parts together to make the finished product. Together DFMA is the philosophy of making the parts and products to be lean from the very beginning. This avoids expensive engineering changes later. It also makes for a lower cost, better reliability, and better-quality product. DFMA pulls in the participation of all the relevant departments (internal and external) at the design stage, where 70 to 80% of a product’s total cost is established. The material to be used, the type of manufacturing process, the assembly processes are all defined at the design stage. Without DFMA bad design decisions may be carried over into the mass production stage where costs and risks to start over are very high. This webinar will examine the application of DFMA philosophy to molded plastic parts – how to produce the molded parts productively, and how plastic parts can incorporate many features that ease assembly into the finished product.

Description: Plastic parts, with their capability for complex shapes, find many structural applications in many high-end industries like aircraft, automotive, and medical. FEA is a very useful tool to predict their structural performance in complicated applications. However, several critical considerations are mandatory if one seeks accurate predictions of stress, displacement, force, etc. This is because plastics do not behave like metals, for which FEA was originally developed for. This webinar will demonstrate the advantages of those critical considerations versus the traditional linear approach.

Description: Creep failure of plastic parts is the permanent deformation of the part in the presence of stress, time, and temperature. Plastics are more prone to creep failure than metals. Because creep failure only manifests itself after time has passed it is usually the customer who experiences it. This has the potential for costly recalls, returns, rework, warranty claims, loss of reputation, etc. And the correction will take a long time to implement because it likely involves a redesign, re-tool and mold, re-test, which prolongs the customer’s pain. Merely replacing the failed part with one of the same vintage will repeat the pain. This webinar will discuss how to identify potential creep failure of plastic parts, and how to design around them.

Description: Fatigue failure of molded plastic parts is the breakage of the part after repeated application of a load (whether a force load or a displacement load) that induced stresses on the parts. The induced stress at which fatigue failure occurs is significantly lower than the Yield Strength of the material. Plastics are more prone to fatigue failure than metals. Just as with creep failure, fatigue failure only manifests itself after time has passed and it is usually the customer who experiences it. This has the potential for costly recalls, returns, rework, scrap, warranty claims, loss of revenue, legal liabilities, etc. And the correction will take a long time to implement because it likely involves a redesign, re-tool and mold, re-test, which prolongs the customer’s pain. Merely replacing the failed part with one of the same vintage will repeat the pain. This webinar will describe and discuss: • What are fatigue failures, along with some examples. • How to identify fatigue failures. • How did fatigue failures happen? • How to design around fatigue failures.

Description: Control of moisture content in the resin is essential for producing quality plastic parts. This is especially so for hygroscopic resins (ABS, nylon, polycarbonate, PET, etc), yet it is an often-overlooked step of the injection molding process. Excess moisture in the resin can show up as splay (or silver streaks) or may manifest itself later as brittle broken parts. The former can be visually caught and rejected, but the latter may make their way into the customer’s hands. And both will hit the bottom line of reduced profits. Moisture control starts with properly drying the resins, but the only real step that matters is the measurement of the moisture content after drying. And this is where many molders are lacking. This KnowHow Webinar will present the defects caused by excessive moisture, the proper steps of drying, cases from industry demonstrating the real missteps of controlling moisture content, and case studies of real defects.

Description: Warpage of a molded plastic part comes down to uneven shrinkage of the part while it is cooling down to room temperature after ejection. Warpage results in a part that is not of the intended shape, and is one of the most common failures. Understanding the causes for the uneven shrinkage is complicated but it is essential. Those causes are material, design, mould, and processing. Using a jig to hold the shape of the part during cooling, after ejection, is not recommended as it can have disastrous results later. This webinar will discuss the various causes of uneven shrinkage and how to mitigate them. A case study will be presented to demonstrate the use of Conformal Cooling to reduce warpage.

Description: DFMA = DFM + DFA, respectively Design for Manufacturing, and Design for Assembly. DFM looks at the cost for manufacturing plastic parts individually. DFA looks at the cost of assembling those parts together to make the finished product. Together DFMA is the philosophy of making the parts and products to be lean from the very beginning. This avoids expensive engineering changes later. It also makes for a lower cost, better reliability, and better-quality product. DFMA pulls in the participation of all the relevant departments (internal and external) at the design stage, where 70 to 80% of a product’s total cost is established. The material to be used, the type of manufacturing process, the assembly processes are all defined at the design stage. Without DFMA bad design decisions may be carried over into the mass production stage where costs and risks to start over are very high. This webinar will examine the application of DFMA philosophy to molded plastic parts – how to produce the molded parts productively, and how plastic parts can incorporate many features that ease assembly into the finished product.

Description: Fatigue failure of molded plastic parts is the breakage of the part after repeated application of a load (whether a force load or a displacement load) that induced stresses on the parts. The induced stress at which fatigue failure occurs is significantly lower than the Yield Strength of the material. Plastics are more prone to fatigue failure than metals. Just as with creep failure, fatigue failure only manifests itself after time has passed and it is usually the customer who experiences it. This has the potential for costly recalls, returns, rework, scrap, warranty claims, loss of revenue, legal liabilities, etc. And the correction will take a long time to implement because it likely involves a redesign, re-tool and mold, re-test, which prolongs the customer’s pain. Merely replacing the failed part with one of the same vintage will repeat the pain. This webinar will describe and discuss: • What are fatigue failures, along with some examples. • How to identify fatigue failures. • How did fatigue failures happen? • How to design around fatigue failures.

Description: Control of moisture content in the resin is essential for producing quality plastic parts. This is especially so for hygroscopic resins (ABS, nylon, polycarbonate, PET, etc), yet it is an often-overlooked step of the injection molding process. Excess moisture in the resin can show up as splay (or silver streaks) or may manifest itself later as brittle broken parts. The former can be visually caught and rejected, but the latter may make their way into the customer’s hands. And both will hit the bottom line of reduced profits. Moisture control starts with properly drying the resins, but the only real step that matters is the measurement of the moisture content after drying. And this is where many molders are lacking. This KnowHow Webinar will present the defects caused by excessive moisture, the proper steps of drying, cases from industry demonstrating the real missteps of controlling moisture content, and case studies of real defects.

Description: A good quality molded plastic part is one that can be molded with high yield and performs flawlessly in its intended application. To this end there are certain best practices to be adhered to by the part designer as well as the toolmaker/molder. In the preliminary stages of part design there is great advantage to leveraging the knowledge and experience of the engineering team of the toolmaker/molder who have likely “seen it all”. This is in contrast to designing in a silo and passing down design features that need costly modifications after mold trials. It is just as easy to design a part feature that will mold well, as it is to design a bad feature that will hamper molding, eg. insufficient draft angle. To do justice to a well designed part, there are also best practices for the toolmaker/molder to adhere to. Here are 30 best practices to get good quality molded plastic parts.

Description: Plastic parts, with their capability for complex shapes, find many structural applications in many high-end industries like aircraft, automotive, and medical. FEA is a very useful tool to predict their structural performance in complicated applications. However, several critical considerations are mandatory if one seeks accurate predictions of stress, displacement, force, etc. This is because plastics do not behave like metals, for which FEA was originally developed for. This webinar will demonstrate the advantages of those critical considerations versus the traditional linear approach.

Description: Warpage of a molded plastic part comes down to uneven shrinkage of the part while it is cooling down to room temperature after ejection. Warpage results in a part that is not of the intended shape, and is one of the most common failures. Understanding the causes for the uneven shrinkage is complicated but it is essential. Those causes are material, design, mould, and processing. Using a jig to hold the shape of the part during cooling, after ejection, is not recommended as it can have disastrous results later. This webinar will discuss the various causes of uneven shrinkage and how to mitigate them. A case study will be presented to demonstrate the use of Conformal Cooling to reduce warpage.

Description: DFMA = DFM + DFA, respectively Design for Manufacturing, and Design for Assembly. DFM looks at the cost for manufacturing plastic parts individually. DFA looks at the cost of assembling those parts together to make the finished product. Together DFMA is the philosophy of making the parts and products to be lean from the very beginning. This avoids expensive engineering changes later. It also makes for a lower cost, better reliability, and better-quality product. DFMA pulls in the participation of all the relevant departments (internal and external) at the design stage, where 70 to 80% of a product’s total cost is established. The material to be used, the type of manufacturing process, the assembly processes are all defined at the design stage. Without DFMA bad design decisions may be carried over into the mass production stage where costs and risks to start over are very high. This webinar will examine the application of DFMA philosophy to molded plastic parts – how to produce the molded parts productively, and how plastic parts can incorporate many features that ease assembly into the finished product.

Description: A good quality molded plastic part is one that can be molded with high yield and performs flawlessly in its intended application. To this end there are certain best practices to be adhered to by the part designer as well as the toolmaker/molder. In the preliminary stages of part design there is great advantage to leveraging the knowledge and experience of the engineering team of the toolmaker/molder who have likely “seen it all”. This is in contrast to designing in a silo and passing down design features that need costly modifications after mold trials. It is just as easy to design a part feature that will mold well, as it is to design a bad feature that will hamper molding, eg. insufficient draft angle. To do justice to a well designed part, there are also best practices for the toolmaker/molder to adhere to. Here are 30 best practices to get good quality molded plastic parts.

Description: Plastic parts, with their capability for complex shapes, find many structural applications in many high-end industries like aircraft, automotive, and medical. FEA is a very useful tool to predict their structural performance in complicated applications. However, several critical considerations are mandatory if one seeks accurate predictions of stress, displacement, force, etc. This is because plastics do not behave like metals, for which FEA was originally developed for. This webinar will demonstrate the advantages of those critical considerations versus the traditional linear approach.

Description: Creep failure of plastic parts is the permanent deformation of the part in the presence of stress, time, and temperature. Plastics are more prone to creep failure than metals. Because creep failure only manifests itself after time has passed it is usually the customer who experiences it. This has the potential for costly recalls, returns, rework, warranty claims, loss of reputation, etc. And the correction will take a long time to implement because it likely involves a redesign, re-tool and mold, re-test, which prolongs the customer’s pain. Merely replacing the failed part with one of the same vintage will repeat the pain. This webinar will discuss how to identify potential creep failure of plastic parts, and how to design around them.

Description: Fatigue failure of molded plastic parts is the breakage of the part after repeated application of a load (whether a force load or a displacement load) that induced stresses on the parts. The induced stress at which fatigue failure occurs is significantly lower than the Yield Strength of the material. Plastics are more prone to fatigue failure than metals. Just as with creep failure, fatigue failure only manifests itself after time has passed and it is usually the customer who experiences it. This has the potential for costly recalls, returns, rework, scrap, warranty claims, loss of revenue, legal liabilities, etc. And the correction will take a long time to implement because it likely involves a redesign, re-tool and mold, re-test, which prolongs the customer’s pain. Merely replacing the failed part with one of the same vintage will repeat the pain. This webinar will describe and discuss: • What are fatigue failures, along with some examples. • How to identify fatigue failures. • How did fatigue failures happen? • How to design around fatigue failures.

Description: Control of moisture content in the resin is essential for producing quality plastic parts. This is especially so for hygroscopic resins (ABS, nylon, polycarbonate, PET, etc), yet it is an often-overlooked step of the injection molding process. Excess moisture in the resin can show up as splay (or silver streaks) or may manifest itself later as brittle broken parts. The former can be visually caught and rejected, but the latter may make their way into the customer’s hands. And both will hit the bottom line of reduced profits. Moisture control starts with properly drying the resins, but the only real step that matters is the measurement of the moisture content after drying. And this is where many molders are lacking. This KnowHow Webinar will present the defects caused by excessive moisture, the proper steps of drying, cases from industry demonstrating the real missteps of controlling moisture content, and case studies of real defects.

Description: Warpage of a molded plastic part comes down to uneven shrinkage of the part while it is cooling down to room temperature after ejection. Warpage results in a part that is not of the intended shape, and is one of the most common failures. Understanding the causes for the uneven shrinkage is complicated but it is essential. Those causes are material, design, mould, and processing. Using a jig to hold the shape of the part during cooling, after ejection, is not recommended as it can have disastrous results later. This webinar will discuss the various causes of uneven shrinkage and how to mitigate them. A case study will be presented to demonstrate the use of Conformal Cooling to reduce warpage.

Description: DFMA = DFM + DFA, respectively Design for Manufacturing, and Design for Assembly. DFM looks at the cost for manufacturing plastic parts individually. DFA looks at the cost of assembling those parts together to make the finished product. Together DFMA is the philosophy of making the parts and products to be lean from the very beginning. This avoids expensive engineering changes later. It also makes for a lower cost, better reliability, and better-quality product. DFMA pulls in the participation of all the relevant departments (internal and external) at the design stage, where 70 to 80% of a product’s total cost is established. The material to be used, the type of manufacturing process, the assembly processes are all defined at the design stage. Without DFMA bad design decisions may be carried over into the mass production stage where costs and risks to start over are very high. This webinar will examine the application of DFMA philosophy to molded plastic parts – how to produce the molded parts productively, and how plastic parts can incorporate many features that ease assembly into the finished product.

Description: A good quality molded plastic part is one that can be molded with high yield and performs flawlessly in its intended application. To this end there are certain best practices to be adhered to by the part designer as well as the toolmaker/molder. In the preliminary stages of part design there is great advantage to leveraging the knowledge and experience of the engineering team of the toolmaker/molder who have likely “seen it all”. This is in contrast to designing in a silo and passing down design features that need costly modifications after mold trials. It is just as easy to design a part feature that will mold well, as it is to design a bad feature that will hamper molding, eg. insufficient draft angle. To do justice to a well designed part, there are also best practices for the toolmaker/molder to adhere to. Here are 30 best practices to get good quality molded plastic parts.
Expert: Mr. Alex Lau holds a B.Sc. in Mechanical Engineering from University of Manchester, and has worked in the R&D’s of several prominent global MNC’s (Novatel Calgary, NORTEL Calgary, Motorola Penang, Agilent Penang, and Seagate Seremban).

Description: Plastic parts, with their capability for complex shapes, find many structural applications in many high-end industries like aircraft, automotive, and medical. FEA is a very useful tool to predict their structural performance in complicated applications. However, several critical considerations are mandatory if one seeks accurate predictions of stress, displacement, force, etc. This is because plastics do not behave like metals, for which FEA was originally developed for. This webinar will demonstrate the advantages of those critical considerations versus the traditional linear approach.

Description: Creep failure of plastic parts is the permanent deformation of the part in the presence of stress, time, and temperature. Plastics are more prone to creep failure than metals. Because creep failure only manifests itself after time has passed it is usually the customer who experiences it. This has the potential for costly recalls, returns, rework, warranty claims, loss of reputation, etc. And the correction will take a long time to implement because it likely involves a redesign, re-tool and mold, re-test, which prolongs the customer’s pain. Merely replacing the failed part with one of the same vintage will repeat the pain. This webinar will discuss how to identify potential creep failure of plastic parts, and how to design around them.

Description: Fatigue failure of molded plastic parts is the breakage of the part after repeated application of a load (whether a force load or a displacement load) that induced stresses on the parts. The induced stress at which fatigue failure occurs is significantly lower than the Yield Strength of the material. Plastics are more prone to fatigue failure than metals. Just as with creep failure, fatigue failure only manifests itself after time has passed and it is usually the customer who experiences it. This has the potential for costly recalls, returns, rework, scrap, warranty claims, loss of revenue, legal liabilities, etc. And the correction will take a long time to implement because it likely involves a redesign, re-tool and mold, re-test, which prolongs the customer’s pain. Merely replacing the failed part with one of the same vintage will repeat the pain. This webinar will describe and discuss: • What are fatigue failures, along with some examples. • How to identify fatigue failures. • How did fatigue failures happen? • How to design around fatigue failures.

Description: Control of moisture content in the resin is essential for producing quality plastic parts. This is especially so for hygroscopic resins (ABS, nylon, polycarbonate, PET, etc), yet it is an often-overlooked step of the injection molding process. Excess moisture in the resin can show up as splay (or silver streaks) or may manifest itself later as brittle broken parts. The former can be visually caught and rejected, but the latter may make their way into the customer’s hands. And both will hit the bottom line of reduced profits. Moisture control starts with properly drying the resins, but the only real step that matters is the measurement of the moisture content after drying. And this is where many molders are lacking. This KnowHow Webinar will present the defects caused by excessive moisture, the proper steps of drying, cases from industry demonstrating the real missteps of controlling moisture content, and case studies of real defects.

Description: Warpage of a molded plastic part comes down to uneven shrinkage of the part while it is cooling down to room temperature after ejection. Warpage results in a part that is not of the intended shape, and is one of the most common failures. Understanding the causes for the uneven shrinkage is complicated but it is essential. Those causes are material, design, mould, and processing. Using a jig to hold the shape of the part during cooling, after ejection, is not recommended as it can have disastrous results later. This webinar will discuss the various causes of uneven shrinkage and how to mitigate them. A case study will be presented to demonstrate the use of Conformal Cooling to reduce warpage.

Description: DFMA = DFM + DFA, respectively Design for Manufacturing, and Design for Assembly. DFM looks at the cost for manufacturing plastic parts individually. DFA looks at the cost of assembling those parts together to make the finished product. Together DFMA is the philosophy of making the parts and products to be lean from the very beginning. This avoids expensive engineering changes later. It also makes for a lower cost, better reliability, and better-quality product. DFMA pulls in the participation of all the relevant departments (internal and external) at the design stage, where 70 to 80% of a product’s total cost is established. The material to be used, the type of manufacturing process, the assembly processes are all defined at the design stage. Without DFMA bad design decisions may be carried over into the mass production stage where costs and risks to start over are very high. This webinar will examine the application of DFMA philosophy to molded plastic parts – how to produce the molded parts productively, and how plastic parts can incorporate many features that ease assembly into the finished product.
