Advantages and disadvantages of hot runner systems

Disadvantages:

1. Difficulty in mold filling

2. Deformation of large thin-walled parts

3. Waste of raw material of runner

4. The quality of the injection molded parts of the multimode cavity die is different.

Advantages:

1. Saving the raw materials and reducing the cost.

2. Shorten the molding cycle and improving the efficiency of the machine.

3. The surface quality and mechanical properties of the products are improved.

4. It is not necessary to use three plate mold, that is, point gate can be used.

5. It is economical to form a single product with a side gate.

6. Improving the degree of automation.

7. Using needle valve gate to control the gate.

8.The quality of the injection molded parts of the multimode cavity die is consistent.

9. Improving the surface beauty of injection products.
