    It makes the automatic forming to save the working time and improve work efficiency without sprue wasted material and post-processing.
  • 3
    It will reduce the plastic material character repeated use of the sprue wasted material. But there is not sprue wasted material using the hot runner system. So it can save the loss of raw materials, thereby reducing the product cost
  • 4
    It is low loss pressure. It is same temperature between the hot runner and injection nozzle.Therefore it is low loss pressure for the injection machines that avoiding the condensation phenomenon on the surface of the runner.
cold runner
The cold runner mold will have the runner scraps.
