Two-shot molding, also called 2K molding or overmolding, produces parts with two different materials in a single molding cycle. The first shot creates a substrate, and the second shot bonds to it to create the finished part. The technology is widely used for soft-touch grips, seals, and multi-colore

The ejector system is the part of the mold that gets the least attention during design, yet it is responsible for one of the most critical functions in the molding cycle. If the part does not eject cleanly, the entire cycle stops. Getting ejection right requires understanding the forces involved, th
