    ASTM A297 Lost Wax Casting / Stainless Steel Valve Castings HD Investment Process

    ASTM A297 HD Investment Process for Valve casting parts HRSC11 EB35003

    Precision casting refers to the general term for the precision casting process.
    Compared with the traditional sand casting process, the precision casting size is more precise and the surface finish is better.
    It includes: investment casting, ceramic casting, metal casting, pressure casting, die casting.

    Precision casting and lost wax casting, its products are precision, complex, close to the final shape, can not machining or rarely used directly, so the investment casting is an advanced technology of formed near net shape.

    Quality Level: As per National Standard & International Standards.

    Special Features:

    1. We can make Valve casting parts with Lost Wax Cast Process

    2. We polished the surface of the casting.

    Production Process: Investment Process,including machining process.
