Advantages of a hot runner system:
1. Shorten the processing cycle and improve efficiency;
2. Replacing the cold runner, thereby avoiding the production of raw material (nozzle material) and eliminating the need for further crushing;
3. Improve the appearance of the gate;
4. Reduce product stress and reduce product deformation;
5. Using valve gate for step-by-step injection molding, processing and manufacturing parts series with different specifications and sizes;
6. Improve more processing control to make precise adjustments to the injection molding process.



More advantages of a hot runner system:
1. Precise control of melt plastic temperature to eliminate material degradation;
2. Balanced flow channel design, evenly filling the part cavity;
3. The appropriate size of the hot nozzle ensures smooth flow of the melt and sufficient filling of the mold cavity;
4. Correct gate structure and size, ensuring full filling of the mold cavity, and timely closure of needle valve gates to reduce casting and shorten
Injection molding cycle;
5. The flow channel has no intersecting areas, ensuring fast color change and preventing material degradation;
6. Minimize pressure loss;
7. Reasonable pressure holding time.
