Since the hot runner does not generate "garbage", there is no problem of dealing with "garbage". Garbage "means the waste of resources, and hot runner systems are low-carbon products that do not produce harmful environmental factors.
Due to the wide variety and often uneven color of plastics, the accumulated material heads during the injection molding process must be classified, dehumidified, dried, and sealed for storage. Meanwhile, the noise generated by crushing can also have adverse effects on the environment.

In summary, the application of hot runners in 3-plate molds has the following advantages:
1. The material head is easy to remove and can reduce the travel of material head removal;
2. During injection, the flow of plastic is relatively even, and the operating conditions of each injection point can be controlled separately to make plastic injection easier;
3. Saved the cost of plastic materials and labor expenses.
