PURPOSE:To release a molded product readily without losing a mold release effect even in the repeated molding using a high temperature mold and improve the workability and utilization efficiency of the mold, by applying the mold release agent composed mainly of a mica to the mold. CONSTITUTION:After a mold release layer is at first formed by applying the mold release agent composed mainly of a mica to a mold, the mold is filled with a fluid molding material and it is molded, then an obtained molded product is released. When a molding is done using the high temperature mold, it is preferable that the life of the mold release effect of the mica layer is elongated by incorporating a silicone resin as a binder to the mold release agent. Further, in the case that the mold has a complex shape, the mold release agent composed mainly of the mica is sprayed as an aerosol. |
