- Thin Wall of plastic products have large deformation.
- Use rate of runneris low.
- It is very difficult tofill the plastic mold.
The advent of hot runner technology has provided a more comprehensive solution to these problems. Generally speaking, hot runner has the following advantages:
- In the runner, the pressure loss is small, the plastic fluidity is good, the temperature is uniform, the internal stress of the product will be reduced, the surface quality and mechanical properties of the product will be greatly improved.
- 2. Shorten the molding cycle, open the mold stroke and improve the production efficiency.
- The hot runner automatically cuts off the gate to improve automation.
- Reduce injection pressure, protect mold and prolong service life.
- Multi-cavity plastic mold ensures uniform packing and consistent quality.
- Eliminate all or most of the waste from the runner, and the effective utilization rate is high.
