摘要：
A method for injection molding overmolded articles includes heating thermoplastic material to a predetermined temperature in an injection molding apparatus (10). The injection molding apparatus has a mold (28) including a mold cavity (32). The injection molding apparatus (10) has a useful life of more than about 1 million injection molding cycles and less than about 20 million injection molding cycles. The method further includes positioning a pre-manufactured article (51) in the mold cavity (32), advancing heated thermoplastic material from the melt holder (20) of the injection molding apparatus (10) into the mold cavity (32) maintaining a substantially constant melt pressure in the proximity of the injection element (30) of at least about 400 pounds per square inch (about 2 MPa) and at most about 10,000 pounds per square inch (about 69 MPa).
