Investment Casting for the Mining Industry

Mining equipment works under abrasive material, continuous vibration and impact. The failure of a small part can stop an entire line.

Why Investment Casting for Mining Parts?

Investment casting produces forms that are hard to machine close to final dimensions. On heat-treated steels, reduced machining can lower part cost.

Typical Parts

Connecting and holding parts, arms and joints, valve and pump parts, conveyor equipment components.

Material Selection

Heat-treated alloy steels such as 4140 are used for wear and impact. Stainless steel is considered for acidic mine water.

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 Mining Parts

• State the type of wear: abrasion, impact or both.
• Add material only where wear is expected, to keep the part weight down.
• Specify heat treatment and target hardness on the drawing.

Frequently Asked Questions

Which materials are used for Mining parts?

Heat-treated 4140 is the usual choice for strength and wear resistance.

What is the largest part you can cast?

We cast parts up to 25 kg. Larger parts are usually better suited to other casting methods.

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.
