Investment Casting for the Automotive Industry

In automotive parts, weight, strength and cost are weighed together. Investment casting can replace machining, especially on small and complex parts.

Why Investment Casting for Automotive Parts?

Parts are produced close to final dimensions, which shortens machining time. Welded or multi-piece components can be converted into a single casting.

Typical Parts

Levers and joints, brackets, turbocharger and exhaust connections, gearshift and mechanism parts, spare parts and parts for special vehicles.

Material Selection

4140 is used for heat-treated parts, stainless steels for corrosion and temperature, and A356 aluminum where weight matters.

Tolerances and Quality

We cast parts to customer drawings. We can produce parts from 1 g to 25 kg and meet VDG P690 D3, the most precise class of the standard. See our tolerances page for the values.

Design Points for Automotive Parts

• State the annual quantity early, since it decides whether casting pays off.
• Mark the datum and functional surfaces on the drawing.
• Consider converting welded assemblies into a single casting.

Frequently Asked Questions

Which materials are used for Automotive parts?

4140 suits heat-treated parts, stainless steels suit corrosion and temperature, and A356 aluminium suits weight-sensitive parts.

Do you cast spare parts for special vehicles?

Yes, investment casting suits spare parts and special vehicles when a drawing or sample is available.

What part sizes and tolerances can you cast?

We cast parts from 1 g to 25 kg and meet tolerances up to VDG P690 D3.

What do you need for a quotation?

A drawing or 3D model, the material and the annual quantity. Price and minimum order quantity depend on the part.
