With energy efficiency, measuring technology and temperature control, the requirements for hot runner systems are becoming more and more demanding.

The hot runner system has advantages as below:

1. Ability to minimize gate vestige

2. Uniform wall thickness

3. Lower cycle times

4. Less waste of product material

5. Reduction or elimination of knit line

6. Great for high cavitation molding

7. Suitable for large molds, while cold runners could not meet the demands
