    摘要: A process for joining a first kind of synthetic resin (1, 101) to a second kind of synthetic resin (2) includes several steps. A first step is providing the first kind of synthetic resin (1, 101), which may include fillers (102), e. g., glass fibers. A second step is setting a second contact surface (21) of the second kind of synthetic resin (2) on a first contact surface (11) of the first kind of synthetic resin (1, 101). A third step is exposing an outer surface of the second kind of synthetic resin (2) to a laser beam. The second kind of synthetic resin (2) transmits the laser beam to the first kind of synthetic resin (1, 101 which stores up heat of the laser beam. The second contact surface (21) of the second kind of synthetic resin (2) and the first contact surface (11) of the first kind of synthetic resin (1, 101) are melted by the heat of the laser beam. A plurality of projections and a plurality of recesses are formed on both the first contact surface (11) of the first kind of synthetic resin (1, 101) and the second contact surface (21) of the second kind of synthetic resin (2). A plurality of the projections of the first kind of synthetic resin (1, 101) engage with a plurality of the recesses of the second kind of synthetic resin (2). If fillers (102) are provided, at least some of them (102) will extend between the first and second synthetic resins (1, 101, 2). Accordingly, the second kind of synthetic resin (2) is securely joined to the first kind of synthetic resin (1, 101).
