ABSTRACT:
Multi-cavity molds, comparatively small in size and stick-like in shape, are passed through mold inspection station, mold locking station, preheating station, a first orientation station, a molding station, a second orientation station, a curing station, an unlocking station, a molded product ejection station, an insert loading station, and to the inspection station again. The molding station provides means for temperature control of a runner and shothead, facilitating use of thermoset materials, with provision for easy cleaning thereof. Insert loading apparatus is employed where the mold product is to include an insert or inserts.
