From CN Mould & Plastic Limited
Molding multiple parts from one pellet's worth of plastic is a challenge that growing numbers of molders want to tackle. It is driving development of new technology in injection machines, tooling, parts handling, and inspection.
Injection molding of parts weighing a fraction of a gram is becoming a sizeable opportunity for molders who serve the electronics, medical, telecommunications, and automotive market sectors. New applications are pushing the limit of what is moldable down to mere dust specksâ parts as light as 0.0003 g, walls as thin as 0.0004 in., and dimensional tolerances to ±0.0005 in. All this is being accomplished with CpK's of 1.3 or better, which translates into no more than six defects per 100,000 parts.
