Investment Casting — Complex Components with High Precision
We offer investment casting, also known as lost-wax casting, for the manufacture of components with very high dimensional accuracy, fine surface finish and complex geometry. The method is ideal for parts with stringent requirements for precision, tolerances and mechanical properties.
Investment casting is a cost-effective solution for both prototypes and series production in industrial, energy, automotive, medical technology and mechanical engineering applications.
What is investment casting?
Investment casting is a process in which a precise wax pattern of the component is created and then encased in a ceramic shell. Once the shell is complete, the wax is melted out and molten metal is poured into the ceramic mould. The method provides very high precision and enables complex geometries that are difficult or impossible to achieve through machining alone.
The method is also known as lost-wax casting or precision casting.
Advantages of investment casting
- Very high dimensional accuracy (tolerances from ±0.1 mm)
- Excellent surface finish (Ra 3.2–6.3 µm as cast)
- Complex geometries without draft angles
- Near-net-shape components — minimal post-machining
- Wide range of alloys: steel, stainless steel, aluminium, bronze, superalloys
- Suitable from single pieces to large volumes
Applications
Investment castings are used wherever demanding tolerances and complex shapes are required:
- Pump and valve components
- Turbine blades and impellers
- Medical instruments and implants
- Automotive and aerospace parts
- Industrial fittings and brackets
Materials
- Carbon steel and alloy steel
- Stainless steel (austenitic, duplex, martensitic)
- Aluminium alloys
- Bronze and copper alloys
- Nickel-based superalloys
