8CH-1938 ABSTRACT OF THE DISCLOSURE A mold apparatus is provided having a stationary injection mold block and a movable compression mold block. A female mold member is formed in the injection mold block whereas the compression mold block contains a movable male mold member so that when the injection and compression mold blocks are placed in an operative position, a mold cavity is defined by and between the female and male mold members. Means are provided to feed a shot of thermoplastic resin into the mold cavity and, at a predetermined time in the mold cycle, move the male mold member into co-acting, mating relationship within the female mold member so that the thermoplastic part obtained is produced by concurrently employing both injection and compression molding principles.
