Plastic molding process demands precise control of melt temperature, melt viscosity, injection speed, injection follow-up pressure, switch over point from speed to pressure, cycle time. It is found that different polymers have different characteristics and different limitations in processing. Shear rate and shear stress influence melt temperature, viscosity, density and flow behavior of polymer. Some polymers are hygroscopic, some polymer have limited thermally stable time which is different at different temperature. Such polymers have limited residence time. The changes in each parameter has its own influences on other parameters.

Plastic injection molding process includes a number of factors, some of them are important. They play a decisive role for the quality in the plastic injection molding processing. Such as freezing time and injection time; maximum injection speed; maximum injection pressure; injection power; plasticizing rate; etc.

And plastic injection molding machine application shaping products directly affect the efficiency of production, quality and cost.
