💡 What is an ejector pin used for in molding?

It's a handy device used to push finished parts out of the mold cavity after cooling, while protecting mold surfaces and part finishes.

- Pushes molded parts free after cooling
- Maintains surface quality and dimensional accuracy
- Durable in high-temperature molding environments
