Abstract
A themial insulation method for an internal surface of an injection molding casting die includes forming a thermal insulation blanket on the internal surface using laser cladding. One or more layers of a metal material having suitable thermal emittance and melting point characteristics is applied to the internal surface using laser cladding. Because the impact area of the injected molten metal is subject to greater stress and temperature gradients than the remainder of the surface, laser cladding can be used to apply the thermal insulation blanket only to areas that require additional protection.
