Many mechanical parts are produced through sintering technology also known as powder metallurgy.
Metal powders, carbides, and ceramics are the most common examples of materials treated with this technology to obtain components with high toughness, wear resistance, or controlled internal porosity.
QP Mechanics builds both powder compaction dies and subsequent calibration dies in hard metal (widia) for powder metallurgy.
Application
Pressing and calibration dies for sintered components
Pressing the powder in molds creates a fragile semi-finished product that can be machined. Sintering then transforms the material by giving it the desired hardness and density.
For components requiring tight tolerances and compatible materials, sintered parts can undergo further calibration in a subsequent forming stage.
The dies and punches used in this process require high geometric and dimensional precision.
The clearances between the dies and punches are often less than a hundredth of a millimeter to ensure proper powder containment, and precise part dimensions, and prevent powder leakage that could create unwanted burrs.
Surface finish is equally important. QP Mechanics prioritizes high-quality mirror polishing, as it affects powder flow during pressing, ease of part release from the die, and the final finish of the pressed component.
