evaporation casting
Evaporation Casting is one of the mold-making processes, which utilize a foam or wax pattern to create a cavity into which molten metal would flow. The pattern is then subjected to heat until it evaporates or burns away during the pouring of the metal, leaving in its place a hollow mold in the desired geometry. The production of intricate or complex parts is typically done by this technique.
Key Features:
- Pattern Evaporation: The pattern is literally the foam or wax that vanishes into thin air as molten metal is poured, leaving no mold to be removed later as in conventional processes.
- High Precision: Low-cost mold production and very easy post-processing of complicated, detailed castings.
- Versatile Materials: Applicable to many metals and their alloys that are found difficult to cast by normal methods.
Evaporation casting is typically the most important and successful in aerospace and automotive applications and even in jewelry making due to its ability to recreate very intricate designs or high-performance materials. It uses complex geometries from castings that may be entirely difficult or impossible to achieve by any other molding or traditional unclamping procedures. In addition, it eliminates complicated mold removal and reduces material waste, making it very efficient and economically wise for high-precision applications.
