SILICA SOL · LOST WAX

Investment Casting Technology

Investment casting, precision machining and surface treatment in one component route.

Stainless steel casting with finished machined features

INVESTMENT CASTING

Cast the shape.
Machine the interfaces.

Silica sol investment casting is used for precision metal components, followed by machining and surface treatment where required.

The material range covers stainless steel, heat-resistant steel, carbon steel, low-alloy steel, high-temperature alloys and nonferrous alloys.

Raw castings, partly machined castings and fully machined parts are included in the manufacturing scope. The delivery condition follows your drawing and agreed requirements.
