AN INNOVATIVE APPROACH TO COMPUTER CONTROLLED CONTINUOUS INJECTION MOLDING

摘要

Modern polymers are continually finding increased application in many diverse products once dominated by metals. They provide an economically viable alternative to traditionally costly metals in many applications where strength to weight ratio, economics, specific mechanical properties and corrosion resistance are required. Injection molding machines are necessary to produce these geometrically complex components now expected of industry. Because many existing molding machines are cyclic they possess an inherent economic loss due to dwell (idle) time. This paper presents some observations obtained from the design of a prototype continuous cyclic injection molding machine together with some preliminary results from investigations into working of the injection molding machine.
