PROBLEM TO BE SOLVED: To provide an injection weld molding method capable of uniformly applying the pressure of a bonding resin to the whole of the bonding parts of primary molded products to obtain sufficient weld strength and preventing the damage of the primary molded products. SOLUTION: When the bonding parts 1a, 2a of primary molded products 1, 2 are mutually abutted in molds 3, 4 and a bonding resin R is injected into the weld grooves M formed to the peripheral edges of the bonding parts 1a, 2a to mutually weld the primary molded products 1, 2, the resin R is injected in such a state that the molds 3, 4 are slightly opened and the molds are clamped after filling to press the resin R charged in the weld groove M. |
