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.

Speaker: 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.
