INTRODUCTION TO PLASTIC INJECTION MOLDING – TOTAL QUALITY PROCESS CONTROL

Plastic components are a critical part of most of our products. However, most organizations do not know what goes into the making of a quality plastic component at a competitive cost. We cannot
afford not to adopt total quality process control procedures. Competition is always knocking at our door and the best way to counter competition is by providing a high quality component within a
realistic time frame at a fair market price.
