Investment Casting Process

    In theory the casting process is just like photography. An image is regenerated through the use of negatives and prints but in casting negatives are molds and our prints are the castings parts.
    Process of Investment Casting:
    In the investment casting process, a wax pattern is coated with a ceramic aterial, which, when hardened, adopts the internal geometry of the desired casting. In most cases, multiple parts are cast together for efficiency by attaching individual wax patterns to a central wax stick called a sprue. The wax is melted out of the pattern – which is why it is also known as the lost wax process – and molten metal is poured into the cavity. When the metal solidifies, the ceramic mold is broken off, leaving the near net shape of the desired part. At last, Finishing, testing and packaging complete the process.
