Mold Modification to Fix Warpage with Cooling Prediction for Plastic Products
Abstract. Warpage is a common quality problem for the injection molded products and it is extremely difficult to solve. Most cases can only be addressed with engineers’ experience. Nowadays, the great advancement of the computer technology makes it possible to simulate the injection molding process with confidence. Such simulations can help us to understand why a warpage problem occurs and how to fix it. Compared to the traditional way, this work is regarding a cooling prediction approach with CAE technology that can greatly shorten the mold modification process and address warpage issues, even after the mold has been produced.
