We are going to make some aluminum cavity inserts for 3 different molded parts that will be interchangeable in a single cavity mold base. I am most comfortable with a steel mold base but am concerned about thermal expansion. The inserts will be about 10" square. The material we will be running these is acetal with a mold temperature of around 125F -160F.
Anyone have any experience with this? My fear is that the inserts will expand and crack the steel mold plates. Am I worried about nothing? Is there a better practice?
