Competency in carbide

Carbide powder blends
Raw materials are blended and wet milled based on the desired carbide quality. Free-flowing, homogeneous carbide powder is produced within the hot gas stream of the spraying tower.

Electronically monitored presses
When carbide powder is pressed into forms – producing so-called green compacts – it achieves approx. 50% of its final density.

Sintering in our oven provides the carbide with its outstanding qualities. Precise process management, which requires specialist knowledge and lots of experience, determines the quality of the carbide.
