ABSTRACT:
Molded plastic parts having inserts associated therewith and a method for their production. The method of the invention consists in providing a mold and positioning an insert in the mold cavity. The insert may comprise part of a latch or nut structure which will ultimately be used for attaching the part to be molded to another part. A pre-molded plastic part is associated with the insert when the latter is placed in the mold. This pre-molded plastic part will be in the form of a cap or other shape which is adapted to at least partially envelope the insert. The plastic to be molded is then introduced to the mold cavity and brought into contact with the pre-molded plastic part. Heat applied to the plastic to be molded, and/or pressure as normally applied during molding, will cause the pre-molded plastic part to deform and take a shape conforming at least in part to the exterior shape of the insert. This will serve to secure the insert in place since, at the same time, the plastic to be molded adheres securely to and bonds with the pre-molded plastic part.
