Investment casting for complex, high-performance parts

Milson provides precision investment casting, also known as lost wax casting, for parts that demand tight tolerances, fine surface finish, and sound metallurgical quality. It is ideal for intricate components in demanding OEM and industrial applications.

The benefits of investment casting

Investment casting is the preferred method when precision, complexity, and consistency matter most. It allows for intricate designs with reduced machining and excellent surface finish.
