Novel Ejector System Eliminates Plates and Pins
Injection mold cost savings, greater molding productivity, and better part quality are promised for a new ejection system that does away with conventional ejector plates, housings, pins, and risers. This approach is said to reduce mold height, shorten mold-open times by at least 10%, enable better optimization of mold cooling鈥攏ot to mention eliminating ejector marks on parts.
