Abstract
PURPOSE: To manufacture the resin plate having the parts of different thicknesses with good operability and quick turnover, by inserting a flat resin plate in metal molds having concave and convex parts and applying heat and pressure.
CONSTITUTION: In comparison with a product 1 to be formed, the flat resin plate 1' has a thinner part than a corresponding thick part 2 of the product 1, has a thicker part than a corresponding thin part 3 of the product 1, but has the same weight as the product 1. Said plate 1' is set in the metal molds (a) and (a') having convex parts (c) and (c'). Then, slight pressure is applied by a heating compressor so that the part to become thin part 3 is heated and melted by the convex parts (c) and (c'), and melted material is flowed to the parts to become thick parts 2 after molding. Then a specified pressure is applied to the metal molds (a) and (a'), heat is applied for a specified time with said pressure maintained, and the melted material and the flat plate 1 are closely contacted to form a unitary body. Then metal molds (a) and (a') are cooled, and the product 1 is taken out when the resin is solidified.
