3. Environmental protection and efficiency of hot runners
Since the hot runner does not produce "garbage", there is no problem of handling "garbage". “Garbage” means waste of resources, and the hot runner system is a low-carbon product that does not have environmentally harmful factors.
Due to the wide variety of plastics and often different color, the material accumulated in the injection molding process must be classified, dehumidified, dried and sealed. At the same time, the noise generated by the pulverization will also have an adverse effect on the environment.
In summary, the application of the hot runner to the three-plate mold of the injection mold has the following advantages:
(1) The material head is easy to take out, and the stroke of the material removal head can be reduced;
(2) At the time of injection, the plastic flow is relatively average, and the operating conditions of each injection point can be separately controlled to make plastic injection easier;
(3) Savings on plastic materials and labor costs.
