Compared with the traditional mold and hot runner, the hot runner system is a common component of the mold system. The hot runner system can effectively improve the quality of plastic products, improve production efficiency, and make the capital investment get a higher return. The main reason why hot runner mold is so widely used is that it has incomparable advantages over traditional molds:

1. Shorten the forming cycle of parts: because the cooling time of the runner system is not limited, the product can be prepared in time. The production cycle of many thin-walled parts and hot runner molds can be less than 5 seconds;

2. Save plastic raw materials: in the pure hot runner mold cold runner, so there is no production cost. This is particularly important for reducing raw material costs. In fact, the world's major hot runner manufacturers are developing rapidly with the high price of oil and plastic raw materials in the world. Because hot runner technology is an effective method to reduce the cost of materials and reduce the cost of materials;

3. Reduce costs and improve product quality: in the hot runner mold molding process, the plastic melting temperature in the flow channel system to obtain accurate control. The plastic can flow into the mold cavity in a more uniform state, resulting in parts with the same quality. In addition, a part of the hot runner of the grid is well molded, the residual stress is low, and the deformation of each part is small. Therefore, many high-quality products are produced through hot runner molds.

4. Eliminating subsequent processes is conducive to production automation. After the completion of the hot runner mold, there is no need to repair the grid and recycle the process of processing the cold runner. It is conducive to production automation.

5. Expand the application scope of injection molding process. Many advanced plastic molding processes are developed on the basis of hot runner technology.
