Used in

Common applications for PCS
Injection molding — PCS nitrided ejector pins (e.g., NP13-10 OS) for ejecting plastic parts from mold cavities in high-cycle production.
Die casting — PCS straight ejector pins (e.g., JMP03-150) for pushing solidified metal parts out of die-cast tooling.
Mold maintenance — PCS leader pins and bushings to restore alignment in worn mold bases and prevent flash or mismatch.
Plastics processing — PCS oversized ejector pins (e.g., NP19-10) for molds requiring increased bearing surface or repair of worn ejector holes.
Tooling assembly — PCS metric ejector pins (e.g., MP015-100) for use in molds built to metric standards.
High-wear applications — PCS nitrided ejector pins with 4–10 uin surface finish for reduced friction and extended service life in abrasive molding compounds.
