The high pertinence between the weight of injection molding products and injection pressure is unveiled by experiments and analyses. The most important evaluation criterion of injection molding products is the weight repetitiveness. Consequently the discovery of the high pertinence provides very important foundation for the new control solution of injection molding machines. On the result, a new method of pressure control is implemented in the whole injection process, and pretty good control result is obtained.
