What is a DIN1530C Nitrided Stepped Ejector Pin?

The DIN1530C nitrided stepped ejector pin is manufactured according to the German DIN1530 standard (C type). Unlike straight ejector pins, this stepped version has a reduced shaft diameter that transitions to a shoulder step. This unique design allows for greater flexibility in mold construction, reduced friction during ejection, and improved mold parting accuracy.

Additionally, the nitriding surface treatment enhances hardness, wear resistance, and fatigue strength, significantly extending service life under demanding operating conditions.

Key characteristics include:

• Material: High-quality tool steel or HSS (high-speed steel)

• Treatment: Nitrided surface for hardness up to 800–1000 HV

• Design: Stepped geometry for reduced contact and improved ejection

• Tolerance: Precision ground to DIN standards for accuracy and smooth operation
