What is the function of pouring runner system and pouring runner structure?What is the effect on injection products?
Casting system refers to the flow channel of the plastic melt in the mold from the injection machine nozzle to the cavity.
Is the role of pouring system the plastic melt smoothly with any part of the cavity, and in the process of filling pressure, transfer injection pressure to various parts of the cavity, in order to obtain clear shape, inner quality of plastic products.
The casting system is slightly different with the type of injection molding machine, but the basic composition is four parts: main channel, diverging channel, liner hole and cold material well.
General design of flow channel structure shape and size selection is reasonable or not, and the liquid flow rate, pressure and injection molding products and the quality of the geometry and dimensional accuracy has great relationship.
