A PROCESS FOR JOINING DIFFERENT KINDS OF SYNTHETIC RESINS

摘要

A process for joining a first plate (10) to a second plate (20) includes several steps. A first step provides a first plate (10) made of a first kind of synthetic resin. A second step is setting a second plate (20) having a hole and formed of metal or a synthetic resin on the first plate (10). A third step is setting an insertion (60) within the hole of the second plate (20) into contact with a portion (11) of the first plate (10). The insertion (60) is made of glass or a second kind of synthetic resin which can transmit the laser beam. The fourth step is exposing the insertion (60) to a laser beam which transmits the laser beam to the first plate (10). The first kind of synthetic resin of the portion of the first plate (10) stores up heat of the laser beam, so that the portion (11) of the first plate (10) is melted by the heat of the laser beam. A fifth step is pressing the insertion (60) into the first kind of synthetic resin melted from the first plate (10). The first kind of synthetic resin melted from the first plate (10) thereby is pushed out from the hole of the second plate (20) onto an outer surface (40) of the second plate (20) to form a lip ring (13) of the first kind of synthetic resin. Accordingly, the lip ring (13) links the first plate (10) to the second plate (20).
