Sinter Parts

Schließen
Sinterpartslogo.png Sinterpartslogo.png
Sinter parts are made by compressing metal granules and heating them below smelting temperature, so that the part stays in the required shape. Advantages are low tooling costs and the possibility to produce high amounts of parts easily.

Typically used in the automotive industry, e.g. for gears, motors or friction brake pads.

Turnparts are made in a cutting process using metal or plastic materials. This process is operated by highly precise CMC machines, which can also handle production of non-round parts. Advantages: high amounts with low wastage and stable quality.

Typical automotive industry applications for turn parts: Suspension parts, motor parts, hydraulic parts...

Sand cast

Schließen

Sand cast parts are made in a casting process using sand moulds. By removing the casting body the mould is destroyed.

This process can be used for production of highly complex shapes.

Gravity cast parts are made in the oldest of all casting processes. Gravity casting has been known for centuries, and it is still used for manufacturing easy and complex shapes due to its simplicity and modular structure. With gravity casting we can reach very exact dimensions and smooth surfaces.

Stamping parts are flat metal parts made from metal sheets. Modern rotary die cutters offer high productivity due to the continuous flow of material that permits a high processing speed.

Stamping processes are suitable for flat parts like cover plates with drill holes.

Pressure

Casting

Schließen

Pressure cast parts are generally manufactured using metallic meterials with a low smelting point. Liquid metal is pressed into a die casting mould with 10 - 200 Megapascal until solidification. Most commonly used materials are zinc, aluminium and magnesium alloys.

Pressure casting is often chosen due to great strength values, smooth surfaces and edges, short casting cycles and a high economic efficiency.

Moulding

Metal Injection Mould Parts are made in a 4-step-process. First the metal powder is mixed with a binding agent composing the raw material. The second step is casting the part by using injection moulding. The final thermal post-treatment processes are debinding and sintering.

This process allows production of precise parts with very low tolerances, cheap mass production and better mechanical and physical properties than with conventional sintering technologies.

Application examples from automotive industry: lock covers, sensor casings, mechanic steering column adjustments.

Diecastparts are manufactured by casting a melt into the upper opening of a permanent mould. The cavity is filled entirely by gravity.

Die casting needs less space compared to sand casting processes and also automatizing of processes is possible by using robots. This process is also suitable for reaching low wall strengths.
