Thermal stress calculation formulas for injected plastics during cooling process

Warpage of injected parts is one of the most difficult problems which often troublesengineers. Because all factors, including process condition, mold structure and materialproperty, have influences on Warpage, it is difficult to control the warpage of big parts bydrawing on experience. To ensure the quality of percision of injected parts, simulating injection process and predicting warpage is an effective method.
