1. Greatly shorten the injection cycle and improve efficiency.

2. The water level of preoducts is smooth and beautiful, which reduces product shrinkage and deformation and improves the appearance of the gate and products' quality.

3. No charge or less material production, which reduces costs and avoid processing twice.

4. As the hot runner makes the plastic unimpeded, the injection force, the clamping force can be reduced, so that some of the original difficult to injection products also become easy.

5. Reduce the stress of the plastic parts and injection.

6. Improve the productivity, profitability and competitiveness of users.
