Design and production of steel and superalloy moulds for cold and sintering presses (hot presses)

Cold press moulds are used for compacting metal powders mixed with diamond to form diamond segments. In order to counteract the devastating abrasive action caused by the diamond, the moulds are made of special teperated steel HRC 63/64.

The metal powders used have a micrometric grain size, and to prevent the material from leaking during pressing, it is necessary that the clearance between punch and die is no more than +/- 0.02 mm.

Moulds for sintering presses are made of nickel-based super alloys, suitable for working at sintering temperatures.

We can supply moulds for all models of both gravimetric and volumetric presses of all makes built in Europe from the 1980s to the present day:
