Abstract

PURPOSE:To simplify a manufacturing process by integrally forming an edge and gasket at the external edge of a disphragm by using a forming mold with the molding cavity of the gasket. CONSTITUTION:External edge 1a of diaphragm 1 is installed in container cavity C1 with forming mold X to blocking the open part at one edge of molding cavity C2. In this state, molten synthetic resin is injected out into cavity C2 to form integrally edge 2 and gasket 3 at external edge 1a of diaphragm 1. After curing, molds are separated to part edge 2 and gasket 3. As a result, edge 2 is formed together with diaphragm 1 being made in one, and gasket 3 is also formed together with edge 2. Consequently, there is no need to bond the edge to the diaphragm, so that the process can be simplified.
