CNC Parts - Hexagonal Ejector Pins

What are ejector pins used for?
These mold ejector pins form and separate the formed parts during the metal stamping process.

Customer Pain Points:
– Material Failure: The current material has insufficient compressive strength, making it prone to plastic deformation or fracture under high-pressure conditions.
– Wear Accumulation : After multiple stamping uses, the head easily wears down, resulting in out-of-tolerance dimensions of the formed parts.

Improvement Plans:
￮ Use Wear-Resistant Material: Adopt tungsten-containing high-wear-resistant high seepd tool steel 1.3343 (DIN standard) / SKH51 (JIS standard) to extend service life.
￮ Heat Treatment: Through vacuum quenching and triple tempering to increase hardness to HRC 60-62, enhancing wear resistance.

Effects:
• The service life is greatly improved, the wear rate is greatly reduced, and the product qualification rate is increased from 80% to 98%.
