Abstract
PURPOSE:To produce reproduced products bearing good resemblance to a master efficiently by vapor-depositing a release agent layer on the specular surfaces of a master female mold, then vapor-depositing a high reflection film thereon, adhering a backing structural body thereon, and pulling these with the mold release agent layer thereby forming the specular surfaces of a polyhedral mirror. CONSTITUTION:Silicone oil is vapor-deposited as a mold release agent 22A on the respective specular surface 77 of a master polyhedral mirror 40, and a highly reflective film 33A of Al or the like is vapor-deposited thereon. This is inserted into the hollow part of a die 51. After these are so set that the center of a revolving shaft 78 and the center of the die 51 align, adhesive of low viscosity is forced into the space between the die 51 and the layer 33A, whereby an adhesive layer 44A is formed. When the polyhedral mirror 44A is pulled out after the curing of the adhesive, the female mold made of metal having the layer 44A and the layer 33A is completed. A mold release agent 33B is vapor-deposited successively on the layer 33A in a similar manner, and a core 40B made of metal is set. After the forcing and curing of the adhesive 44V, the mirror is pulled from the die, whereby the reproduced product bearing good resemblance to the master is produced with good efficiency.
