Abstract

PURPOSE:To obtain a stable diaphragm with a low cast by previously inserting the edge of a prescribed form into an injection molding metal mold, and integrating the mold of a cone prototype product by the injection molding metal mold with the edge simultaneously. CONSTITUTION:The edge prototype product 2b is formed from an edge molding substrate 2a by a press metal mold 4 for molding the edge, trimmed to a prescribed dimension to obtain the edge 2. This edge 2 is set in the injection molding metal mold 3 of the cone, a molten resin is filled under pressure to mold the cone prototype product 1a, thereafter, the integrated material is taken out from the metal mold 3 and by the prescribed trimming for the cone prototype product thereafter, the diaphragm is completed. Thereby, it is not necessary to use an adhesive separately, a labor is not required for forming and the product stable in a quality can be obtained at the low cost by simplifying a process or saving the cost of the mold.
