Investment Casting Waxes
Investment casting waxes are specially formulated waxes used in the process of investment casting.
Investment casting, also known as precision casting or lost-wax casting, is a manufacturing process that involves using a wax pattern to shape a disposable ceramic mold. The ceramic mold is used to replicate a desired pattern in materials typically made out of common metals such as aluminum, bronze, magnesium, and stainless steel.
The process gets its name from the process of “investing” or surrounding a pattern with refractory materials.
Application of Investment Casting Wax
First, a wax pattern is made in the exact shape of the item to be cast. Then, the wax pattern is coated with a refractory ceramic material. Once the ceramic material hardens, it is turned upside-down and heated until the wax melts and drains out, leaving an expendable investment mold. Molten metal is then poured into the mold and allowed to solidify. The resulting metal casting is broken out of the spent mold.
