From powder to solid component

Sintering as a manufacturing process for metallic components is the right choice for workpieces with special geometries, such as compact gear wheels, pinions, bearings or housings, which can be produced ready for installation (also with heat treatment).

BENEFITS

Development, production, just in time delivery
No mechanical finishing
Economical for high quantities
Narrow dimensional tolerances
No excess material

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.

Manufacturing process

Mixing

Powders are mixed together in the ratio of the desired alloy.

Powder production

Metallic powder is produced by water atomization. The rapid cooling results in brittle powder, which can become mechanically entangled during subsequent pressing.

Pressing

Several press dies are used to press the powder into green compacts under high pressure.

Sintering

Green compacts are sintered below the melting temperature.

Calibrate

The final calibration impact eliminates the smallest inaccuracies and greatly increases dimensional accuracy.

Quality control

The component is checked for compliance with the drawing specifications and material properties.
