Abstract
An improved mold apparatus (10) includes a cutout (30) between the nozzle cap sealing surface (32) and the injection mold cavity (14) configured for receiving the tip (38) of an insert (20). The cutout (30) shortens the material passage (24) leading to the mold space (22) between the mold cavity (14) and core (12) so that the resulting molded product presents a short gate. The cutout (30) is also configured so that material space surrounds the tip (38) for receiving mold material in order to surround and thermally insulate the tip (38) from the injection mold cavity (14).
