Plastic Molding, Engineering Simulation, Design for Manufacturing
ID: 730056
Washington, USA
TPE Molding over 6 layer Flex PC with components causing variable cross sections resulting in 'Tiger stripes', shiny spots. Trouble shooting with Moldflow simulation, DOE (Design of Experiments), work with material supplier's lab, tool heat exchange debugging fill/pack debugging Also resolving bonding and de-laminination issues.Simulate conformal cooling and process settings to minimize warpage, use cavity pressure and temperature sensors to optimize parameter settings for flatness and cosmetics. End result was the best shape/cosmetics performance of supplier candidates in China.Designed out Optical lens weld lines and air entrapments by using Moldflow.End result was very fast setup and part acceptance.Work with external material & Moldflow consultants for complex gas assistance problem. Reviewed and assisted in gas assistance issue for a very large transparent part.
