Ejectors and cores made ​​of hard metal

The outstanding properties of hardmetal gain importance in the tool and mold making field. Hard metal has gone from being brittle and fragile to a high quality material and almost for any kind of use. Higher demands in life time and precision make it necessary for special tools to be made of hard metal. This way, ejectors and mold cores are made out of hard metal for this precise purpose. The use of these hard metal parts results in a significant increased of the tool life compared to WAS and HSS, which leads to significant production cost-savings.

Advantages of hard metal punching

Advantages of hard metal forming/injecting

• Stamp life time increased
• Higher lifting speed
• No anti-wear coating necessary
• Corrosion-resistant
• Longer maintenance intervals

  • Cores with high wear resistance

  • In spite of the hard metal, there is a benging strength of 3600 N/mm

  • excellent thermal conductivity of 85, for comparison: WAS / HWS / HSS are between 28-32

  • lower irrigation


Longer life time thanks to less wear compared to conventional tools.Reduced downtime thanks to tool changes contribute significantly to the improvement of the cost structure.

Faster cycles can be accomplished by the slower heat absorption of hard metal compared to steel.

Ejectors and cores are available in various lengths, diameters and with different surface coatings. We also offer customized shapes and designs.
