Investment casting is known as the "lost wax casting process" and as "precision castings (silica sol precision casting process)".
Investment casting is an advanced metal forming process used to produce metal parts in high quality, functionality and cost-effectiveness. Lost wax casting process is a one-to-one process in which one disposable pattern produces one metal part. When combined with modern production knowledge and technologies, it can be applied to produce parts of varying degrees of complexity, in virtually any volume and for the broadest possible spectrum of applications.
A highly versatile casting process, lost wax casting has for some time been perceived as a comparatively expensive process. But when compared to alternative processes which require extensive welding or machining, an investment cast component can often dramatically reduce overall part production costs. Of course, investment casting is not the appropriate process for every metal part requirement. However, for many challenging part applications, investment casting offers a proven and cost-effective metalforming solution.
LOST WAX CASTING PROCESS
Investment Casting. Often called lost wax casting, is regarded as a precision casting process to fabricate near-net shaped metal parts poured from almost any alloy including: stainless steel, aluminum, brass, bronze and copper.
Casting by the investment process allows for parts to meet x-ray and non destructive testing specifications for: military, aerospace, semi conductor industry, valves, pumps and many other industrial applications.
The investment casting process consistently provides high integrity (sound) and dimensionally accurate castings. Cast part dimensions vary less than +-.001 from part to part.
Investment casting uses a mold that has been produced by surrounding an expendable pattern with a refractory slurry that sets at room temperature. The pattern (usually of wax or plastic) is then melted or burned out, leaving the mold cavity. Investment casting is also known as the “lost wax process” and as “precision casting”.
