Method of making a mold by spraying metal using a particulate mold release agent |
摘要 |
A method including: based on a primary mold having a surface pattern identical with that of a composition to be produced, making a secondary mold having a low melting point sprayed metal layer of Zn or the like to which the surface pattern of the primary mold is transferred; next, after carrying out mold-releasing treatment on the secondary mold surface, spraying a high melting point metal such as Ni or the like; reinforcing the back side of the thus-formed high melting point sprayed metal layer with FRP or the like; hardening said FRP or the like; and then, releasing a composition consisting essentially of the high melting point sprayed metal layer and the reinforcing resin layer from the secondary mold.
