Investment casting materials

Maximum precision through investment casting

The investment casting offers unlimited design freedom. In this way, small to large components, even with complex geometries, can be produced in great detail.

Since the workpieces can be poured cleanly, we get a high surface quality through investment casting that does not have to be reworked or only needs slight finishing touches.

Depending on your specific requirements, different materials such as steel, stainless steel or aluminum as well as other alloys can be processed.

Whether cast steel or cast aluminum, we attach great importance to precision and the highest quality standards in order to determine the technically optimal manufacturing process for your component or assembly. In this way we save costs and can implement your casting economically.

How does the investment casting work? What is the background to the process? We are happy to give you a comprehensive overview.
More about investment casting

During investment casting, metal is brought to its melting temperature and poured into molds. Since both the model and the mold are no longer available after casting, this process is also called casting from lost models and lost molds.
