Used in

Common applications for PCS
Injection molding — PCS stepped ejector pins (e.g., SP3-83) for ejecting parts from core cavities
Die casting — PCS hard core pins (e.g., CPH15-3) for forming internal features in aluminum or zinc dies
Slide actuation — PCS radius angle pins (e.g., APR33-L10) for guiding core pulls in mold bases
Mold support — PCS support pillars (e.g., 1550) to prevent plate deflection in large injection molds
Ejector plate alignment — PCS shoulder bushings (e.g., BU-102) for guiding ejector pins in mold bases
Wear protection — PCS stop discs (e.g., SD-15) to limit ejector stroke and prevent over-travel damage
