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.
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). He has >30 years experience, specializing in the design and development of parts/products that are toolable and manufacturable, and that function flawlessly in their intended applications. His CAE simulations (FEA, Moldflow, CFD) in product development have consistently predicted accurate results that correlate very well with the actual applications. Mr. Lau applies his knowledge in engineering fundamentals, design guidelines, and CAE simulation to achieve ‘Do It Right the First Time’. This had resulted in projects staying on schedule, on-cost, and on-quality virtually every time. He has trained engineers in many MNC’s, SME’s, and Skills Development Centres, over the years. Mr. Lau is a certified PSBM (HRDF) trainer, as well as a holder in Certified Advanced and Expert Scientific Injection Molding. He also holds US Patent 6853492 Conductive Lens.
