Paper Title:
Study of the Influence of Polymer Properties on Injected Parts and the Controlling Means
  Abstract

At present, the trends for injection molding are higher precision, ultra-thin and light weight, and there are many harsh requirements on injected parts. For the parts manufactured by injection molding, crystallization and orientation of polymer affect the properties of the parts greatly. Crystallization and orientation affect the physical and chemical properties of the injected part, such as strength, stiffness, impact resistance, erosion resistance and so on. According to their formation mechanism, this paper presents the layout and dimensions of the coolant lines, the position, shape and dimensions of the gate, and the injection pressure etc., which play an important role for controlling the degree of crystallization and the direction and degree of orientation.
