Method of making a mold by spraying metal using a particulate mold release agent

A method for producing a composition consisting essentially of a metal layer made by metal spraying and a resin layer which reinforces said metal layer comprising:

• making a primary mold having a surface pattern which is a positive pattern of the surface of the finished molded composition;
• applying a first mold release agent on the surface of the primary mold;
• spraying a low melting point metal onto the primary mold surface to make a low melting point sprayed metal layer;
• reinforcing the low melting point sprayed metal layer to make a secondary mold comprising the low melting point sprayed metal layer and the reinforcing substance;
• releasing from the primary mold the secondary mold having the negative surface pattern of the primary mold on the low melting point metal;
• applying a mold-releasing treatment on the surface of the secondary mold, wherein the mold-releasing treatment involves the application of a second mold release agent containing inorganic particles having an average particle diameter of from 0.05 to 20 .mu.m on the surface of the secondary mold;
• spraying a high melting point metal having a melting point of 1,000.degree. C. or higher onto the secondary mold surface;
• applying a reinforcing resin layer to the high melting point sprayed metal layer;
• hardening said resin layer;
• and
• releasing the finished molded composition consisting essentially of the high melting point sprayed metal layer and the reinforcing resin layer from the secondary mold.
