RUKO Ejector Pin TX Mod.30 6.35x77mm

Injection molding and die casting operations rely on precision ejector pins to release finished parts from the mold without damage. The RUKO GMBH Ejector Pin TX Mod.30 6.35x77mm is built for exactly this task, combining high-grade hot work steel with a precision-ground, nitrided surface for consistent performance in demanding production environments.

Key specifications

• Nominal diameter: 6.35 mm
• Nominal length: 77 mm
• Head diameter: 10 mm
• Head thickness: 3 mm
• Material: High-grade hot work steel (1.2343 / H13 equivalent)
• Shaft hardness: 60-64 HRC
• Head hardness: 45-50 HRC
• Diameter tolerance: h5
• Length tolerance: ±0.2 mm
• Surface finish: Precision ground, nitrided
• Temperature resistance: Up to 200°C
• Standard compliance: HASCO Standard

Why choose it

With a shaft hardened to 60-64 HRC and a head at 45-50 HRC, this ejector pin balances wear resistance with toughness to withstand repeated ejection cycles. The precision h5 diameter tolerance ensures a proper fit in HASCO standard mold plates, while the nitrided surface provides good corrosion protection and very high wear resistance.

Ideal use cases

• Injection molding of thermoplastics
• Die casting of non-ferrous metals
• Mold bases and tooling systems compatible with HASCO standards

Good to know

Manufactured by forging and precision grinding, this ejector pin is part of the Z45/30 series and is designed for reliable operation in high-volume production settings.
