Non Standard BOHLER M300 Die Steel Ejector Pin For Daily Cosmetic Plastic Parts

Steel pins manufactured from premium 1.2343 material and hardened, typically cylindrical in design (featuring cylindrical or conical heads), specifically engineered for ejecting castings from gravity dies, pressure dies, and core boxes.

Cylindrical ejector pins with cylindrical heads conform to DIN ISO 6751 (DIN 1530-1) standards, while pins with conical heads adhere to DIN 1530-3 specifications. The comprehensive range of ejector pin types is illustrated in industry-standard diagrams.

Core ejector pins are categorized as blind and contour types. Blind ejector pins facilitate core box opening by applying pressure against the opposite parting surface during core material hardening. These ejectors must be recessed approximately 0.2mm from the parting surface in retracted position to ensure proper core box sealing. Contour ejector pins maintain flush alignment with core box contours, neither protruding nor recessing. Hollow variants are designated as ejector sleeves.

Die casting applications typically employ cylindrical ejector pins with cylindrical heads, manufactured from hardened and nitrated 1.2343 material for optimal performance.
