Investment Casting for the Construction Industry

Construction machinery and building equipment work under heavy loads, impact, dust and weather. Spare part continuity matters as much as strength.

Why Investment Casting for Construction Parts?

Casting complex connecting parts as one piece reduces welding and assembly. Because dimensions stay consistent across series orders, spare parts are easier to replace.

Typical Parts

Joints and connecting elements, arms and brackets, locking parts, connectors for scaffolding and formwork systems.

Material Selection

Heat-treated 4140 steel provides high strength. Low-carbon steels are preferred for welded parts and stainless steels where corrosion is a risk.

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 Construction Equipment Parts

• Identify which parts will be welded, since this affects the alloy choice.
• Add generous radii at joints that take impact loads.
• Keep the drawing revision fixed so spare parts stay interchangeable.

Frequently Asked Questions

Which materials are used for Construction Equipment parts?

Heat-treated 4140 suits high-strength parts, and low-carbon steels suit welded parts.

Are investment cast parts suitable for welding?

Low-carbon steel castings are generally the better choice for parts that will be welded.

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.
