Transmission covers must perform in a very severe environment of high temperature and transmission oil contact. The original concept was to use a high temperature engineering resin such as PPS or PEEK. After further investigation, it was found the PA66 could offer the needed temperature performance and oil resistance. Testing and production vehicles have proved the concept is successful.
Ascend’s Vydyne R533H is ideal for this application because of its superior temperature resistance and chemical resistance. The high flow of the product allows the complex design features to be molded with ease. This part also provided a significant weight reduction over the aluminum design. The Ascend automotive team uses mold flow analysis and years of automotive experience to create optimal parts for Ford,® General Motors,® Chrysler® and Toyota.®
