Abstract

The injection mold has two functions. It forms the air space into which the hot plasticized material is injected under pressure, and it acts as a heat exchanger, removing heat from the material in the mold until it is rigid enough to be ejected so that the final part will conform to all its specifications. The quality of the part and its cost of manufacture are largely dependent on mold design, construction, and excellence of workmanship.

The author gratefully acknowledges the permission of John Wiley & Sons, Inc., New York, to use material from his book Injection Molding, Theory and Practice (1973).
