Production is underway at my day job on the 20 mold project. My department had a small personnel problem, and a 3 day equipment break-down. Those 2 things put us a little behind schedule but we'll soon recover. One aspect of the design is still up in the air, and that is which air poppets we will use to blow the part out of the mold. The main trouble is the poppets are steel & the molds are aluminum, the aluminum operates at an elevated temperature which makes the aluminum expand. When the air blast is blown through the poppet, the steel poppet cools and contracts and the poppet comes out of the mold. To make a long story short; I may end up designing my own air poppet to best fit our application, depends on what the president opts for.
