Abstract: A method for injection molding overmolded articles includes heating thermoplastic material to a predetermined temperature in an injection molding apparatus. The injection molding apparatus has a mold including a mold cavity. The injection molding apparatus 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 in the mold cavity, advancing heated thermoplastic material from the melt holder of the injection molding apparatus into the mold cavity maintaining a substantially constant melt pressure in the proximity of the injection element 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).
