Creep Failure of Molded Plastic Parts and Design Guidance
Language: English
ID: KH0387
Time Length: ~85 Min
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.

Moisture Control for Quality Molded Plastic Parts
Language: English
ID: KH0394
Time Length: ~105 Min
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.

Understanding the Polyolefin Business
Language: English
ID: KH0503
Time Length: ~90 Min
Description: The Polyolefins (PO) business is a global one, played on a regional scale. POs such as polyethylene (PE) and polypropylene (PP) are the most common plastics. Resin production has moved from the regions where technologies were originated and still continue to be developed, to regions with low cost, abundant raw materials and regions with high demand, but with higher cost raw materials. The total cost of producing POs consists of variable costs and fixed costs. The single largest item is the monomer cost, ranging from 80 to 85% of the total costs. There are several routes to ethylene and propylene, the PO monomers. All modern PO polymerization technologies are capable of producing competitive grades but each generic technology has strengths and limitations. PO resins are sold to tens of thousands of processors throughout the world. They range from large multinationals with the most modern equipment to very small family operations.

Fatigue Failure of Molded Plastic Parts and Design Guidance
Language: English
ID: KH0395
Time Length: ~75 Min
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: Thermal characterization of materials by using the DSC, TGA, and SDT are important techniques that are used by a wide variety of industries, including polymers, composites, pharmaceuticals, foods, petroleum, inorganic and organic chemicals, and many others. These instruments typically measure heat flow, specific heat capacity, weight loss, as a function of temperature and time. Properties characterized include melting, crystallization, glass transitions, cross-linking, oxidation, decomposition, and volatilization. These experiments allow the user to examine end-use performance, composition, processing, stability, and molecular structure, and mobility of the materials. Advanced thermal characterization techniques such as the Modulated DSC (MDSC), High-resolution TGA (Hi-Res), Modulated TGA, etc. are suitable for high sensitivity R&D as well as that are helpful to understand better the complex material behaviors, which is sometimes quite difficult to measure using the conventional techniques. The KnowHow Webinar will highlight those advanced characterization techniques along with their application examples related to polymeric materials such as plastics, composites, rubber, etc.

Design for Manufacturing & Assembly (DFMA) for Molded Plastic Parts
Language: English
ID: KH0415
Time Length: ~90 Min
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.

Rheology of Thermosets
Language: English
ID: KH0538
Time Length: ~60 Min
Description: Thermoset polymers form the matrix in filled plastics and fiber-reinforced composites used in a diversity of products. These range from consumer items and auto body panels to advanced composites for printed circuit boards, aerospace structural components, and expensive, high-performance sports equipment. Rheological measurements have become the most important characterization technique because of their sensitivity to small changes in structure and the ease to monitor these structural changes. For the thermoset polymers, rheology (including dynamic mechanical analysis) provides details of structural changes, the gel point, and also processing parameters such as viscosity as a function of time. The advantage of the rheological technique is that it allows probing of the sample during the reaction with a small oscillatory deformation, which can generate viscoelastic material properties, such as the storage modulus, the loss modulus, and the tan delta all of which are characteristic of the changes of the material’s structure during cure. The KnowHow Webinar will demonstrate the various applications of the rheological characterization technique in the thermosetting polymer to predict its process behavior and how to evaluating its product performance.

30 Best Practices for Quality Molded Plastic Parts
Language: English
ID: KH0402
Time Length: ~120 Min
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.

Warpage Failure of Molded Plastic Parts and Guidance
Language: English
ID: KH0404
Time Length: ~80 Min
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: This is the first edition of KnowHow Q &A Session focusing on Quality Molded Plastic Parts Design. Participants asked followed questions on various issues related to design and failures of molded plastic parts. Mr. Alex Lau addressed all the real questions/ issues raised by participants, which was held on 2 April 2021. The questions/issues addressed in this Q&A session are: # How does under-cooling of the molds cause warpage?; # I had dried the resins and checked the moisture content to specification before molding, why did the parts break in one batch of molding but not another batch?; # I’ve used FEA, found that it’s not accurate. Any suggestions why?; # Can I allow my toolmaker to add the draft angles for me, since he’s very familiar with the requirements?; # Should I use ribs to help reduce warpage?; # If I use FEA to accurately calculate the stress, and considered creep performance of plastics, the part should last a long time?; # What is nonlinear FEA?; # Theoretically, to eliminate warpage, can I leave the part in the mold until it cools down to room temperature?; # I measured the moisture content when the bags of resins were received. I rejected those that exceeded the limits, then used the remainder without further moisture content checks. Is this ok?; Can I have zero draft angle on some features?; Nonlinear FEA takes too long. Can I use linear FEA for fast answers?; The molded part broke but I don’t see those fatigue ‘beach marks’ on the surface of the break. Why?; # Can DFMA help to reduce cycle time of molding?; # I used hand calculation to determine the working stress in the plastic structural part. Is this good enough? # My toolmaker does the Moldflow analysis for me. Why not continue as is?; # What is MFR?; # I practice DFM and FMEA quality processes in my company. Why didn’t they identify potential fatigue failures?; # Why are the glass-reinforced plastics more resistant to creep?; # I don’t have an FEA analyst in my company. Can I out-source the job?; # I’ve done nonlinear FEA with mesh refinement. The production part was tested and its performance correlated with the FEA predicted results, all well and good. Some weeks later the production part still broke, how come?; If the molded part is not compliant to UL Flammability can I change to another grade that is compliant?; For a desiccant dryer machine can I set to -20C dew point?; My FEA reseller did not tell me about nonlinear FEA. Why was that?; My designs are out-sourced. How can I be sure the out-sourced designer had taken fatigue failure into account?; I used a jig to hold the warped part straight during cooling after ejection. Fortunately, I have not had problems with the parts warping back at a later time. Why was that?; In a plastic part that failed by deformation or breakage, why not just change to a stronger plastic?; Can I modify the gates, molding parameters, temperatures, etc. to eliminate fatigue failure?; Can cosmetic defects be removed by adjusting the molding parameters?; Is Conformal Cooling expensive?; How good is the Boothroyd & Dewhurst DFMA software?

Technology for Producing Plastic Cellular Materials (Polymeric Foams)
Language: English
BuffPack
ID: KH0541
Time Length: ~60 Min
Description: Cellular materials are solid foams. They are often produced to take advantage of the properties of the solid material whilst at the same time taking advantage of their light-weighting characteristics. The light weight enables their insulation performance since gas is a poorer thermal conductor than solids. This Webinar explores the various technologies for producing cellular plastics (polymeric foams) from various polymer classes. The Webinar will cover aspects of foaming both thermoplastics and thermoset polymers. Thermoplastic polymers are those which are converted to foams starting from fully formed polymers which are processed through softening (melting or devitrification) and then followed by foaming. The end of foaming is accomplished by freezing the cellular structure through recrystallization or vitrification. Thermosetting polymers are those which start from liquid monomeric raw materials which undergo cross-linking chemical reactions to form a solid polymer. The foaming process happens simultaneously with the cross-linking reactions. The KnowHow Webinar will highlight the advantages and disadvantages encountered in foaming thermoplastic and thermoset polymers.
Expert: Dr. Bernard E. Obi is a retired dynamic polymers/materials scientist with extensive expertise in cellular materials in general; but particularly in polyurethane foams processes and applications. He has extensive expertise in both rigid and flexible polyurethane foams.

He earned a Ph.D. in chemical engineering and worked for The Dow Chemical Company from July 1985 to July 2015. Apart from polyurethanes technology; he also has significant expertise in free radical dispersion/suspension polymerization, surface and interfacial science, micro & macro-structure-property-performance relationships, materials development, composites, elastomers and rubbers. He authored a text book on Polymeric Foams Published December 7th 2017 by Elsevier Publishers. Dr. Obi operates his consulting company (PolyFoam Consulting LLC) out of the Houston area in Texas USA, and is engaged in providing consulting services to the polymeric foams industries and businesses.
Thermosets Foams Processing Fundamentals
Language: English
ID: KH0542
Time Length: ~60 Min
Description: Thermosetting polymers are those which start from liquid monomeric raw materials, and undergo cross-linking chemical reactions to form a solid polymer. The foam expansion reaction which is called the blowing reaction is usually relatively very fast. The foam expansion process is typically completed between 60 to 90 seconds in most thermosets foaming processes. The gelling reactions which build polymer structure, hardness and strength takes relatively long time to complete, typically requiring several hours for completion. The purpose of the fast blowing expansion reaction is to minimize drainage which leads to foam instabilities and poor foam quality or in the worse case complete foam collapse. Thus the need to expand quickly has to be balanced with the equal need to polymerize (i.e. gelling reaction) quickly enough to stabilize the foam, whilst not too fast to retard both the foam expansion and cell opening for flexible foams. In addition to the balanced gelling reaction, surface active agents are typically used to provide the complex interfacial phenomena that provide stabilization in foaming processes that begin from the liquid state. The Webinar will highlight the complexities encountered in production of thermosetting polymeric foams, including the role of surface active agents, the balance of blowing-to-gelling reaction to control both polymer and cellular properties.
