摘要：
This paper reports on work carried out to adapt the extruder-barrel venting to reciprocating-screw molding. A design of a typical two-stage, vented reciprocating-screw and barrel assembly is presented and its operation technique described in some detail. Numerous polymers have been evaluated in the vented-screw reciprocating injection unit. Molding of ABS was the first commercial application of vented injection molding. Other materials injection molded include - acetal resins, cellulosic materials, nylons, polycarbonates, PPO, and PMMA. Technological recommendations are included.
