The pouring system is the flow channel of the plastic mold from the nozzle of the injection molding machine to the entrance of the cavity. It can be divided into ordinary runner pouring system and non-runner pouring system. It is an indispensable and important link in the molding process of the product. Therefore, the pouring system must have a good design and certain principles must be followed during the design.

Plastic mold

1. In order to facilitate the balanced filling of each cavity in the mold by the molten plastic, the arrangement of the mold cavity should be balanced, and the arrangement should be compact, which can effectively reduce the mold size.

2. In order to ensure that the mold is evenly stressed during the injection molding process, the distribution of the cavity and the location of the gate should be determined according to the structure and characteristics of the product.

3. Correctly select the runner section, and at the same time reduce the degree of bending and surface roughness, which can effectively reduce the loss of heat and pressure.

4. Reasonable runner size is very important. Generally, a large-sized runner system can reduce flow resistance. If the pressure of the runner system is small, a small size is preferred, which can reduce material consumption and shorten cooling time.
