• How to Design a Mold(the first part)

      INTRODUCTION The basic function of a mold is two fold. Firstly it should impart shape to the part secondly it should cool the molded part. The number of cavities mainly depends up on the production volume requirement. But it is also related to the size and weight of the parts which in turn determines the machine capacity required. It is also important to design a mold that will safely absorb the forces of clamping, injection and ejection. Further more the mold lay out should be balanced which will ensure proper filling and dimensional control DECIDING THE TYPE OF MOLD There are several types of injection molds in use today. Two plate. Multi plate mold. Hot runner mold Insulated hot runner mold Hot runner manifold stack mold   A two plate mold has got only single day light (one opening). All basic designs of injection molds have this design thought….
