Ceramic Foam filters are just developed as a new type molten metal filter to decrease casting flaw in recent years. With its characteristics of light-weight, high mechanical strength, large specific surface areas, high porosity, excellent thermal shock resistance, erode resistance, high-performance, ceramic foam filter is designed for filtering impurities from liquid metals.
Placed properly within the gating system, they effectively remove non-metallic inclusions including slag and dross from the molten metal stream. Capture non metallic inclusions improve strength, ductility, and fatigue resistance of the metal. Additionally, they also aid in reducing turbulence in the gating system , provide lamina flow of metal , and trapped gas that enters the mold cavity.
