Investment Casting for the Defense Industry

Defense parts call for strength, dimensional consistency and traceability. Investment casting suits series production of complex parts at consistent quality.

Why Investment Casting for Defense Parts?

Combining several parts into one casting reduces weight and assembly. Aluminum and magnesium alloys can also be cast where low weight is needed.

Typical Parts

Mechanism parts, housings and covers, brackets, levers and connecting elements. For weapon parts, see our firearms page.

Material Selection

4140 and low-carbon steels are used for parts that need strength, stainless steels where corrosion is a risk, and aluminum and magnesium for lightweight parts.

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 Defence Industry Parts

• State any applicable standards and inspection requirements with your enquiry.
• Mark critical dimensions and surfaces on the drawing.
• Agree on heat treatment and mechanical test requirements before tooling.

Frequently Asked Questions

Which materials are used for Defence Industry parts?

4140, low-carbon steels and 316 and 304 stainless steels are the most common choices.

Do you cast firearm parts?

Yes, we cast parts for rifled and smoothbore long guns and pistols.

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.
