发明名称 APPARATUS FOR INJECTION MOLDING
摘要 The injection molding machine has an extruder for providing molding material , a cavity for retaining the molding material prior to injection into a mold, a plunger within the cavity to move the material out of the cavity, and a check valve. The check valve has separate means to permit the material to flow from the extruder to the cavity and from the cavity to an adjacent mold. By having separate flow channels for molding and recharging, the injection molding machine may be recharged on the fly.</SDOA B>
