Sintering allows shaping without heating the material. The metal powder is pressed into green compacts in matrices at different pressures and sintered in a further step at temperatures just below the melting point. The powder particles melt together at their contact surfaces and the workpiece gets its dimension and design. Due to a final calibration impact, the workpieces have a very high level of dimensional accuracy.
The process is therefore an effective, environmentally friendly and economical process, especially for large quantities.
