How to overcome the problem of turbidity at the gate of injection molded products

The appearance of spots and turbidity at the product gate is usually caused by "melt fragmentation" during expansion injection into the model.
1、 Injection molding issues:
1. Increase the temperature of the material barrel;
2. Raise the nozzle temperature;
3. Slow down the injection speed;
4. Increase injection pressure;
5. Change the injection time;
6. Reduce or replace lubricants.
2、 Mold problems:
1. Raise the mold temperature;
2. Increase the size of the gate;
3. Change the shape of the gate (fan-shaped gate);
4. Increase the cold material cavity;
5. Increase the size of the diversion channel;
6. Change the gate position;
7. Improve exhaust.
3、 Material issues:
1. Dry materials;
2. Remove pollutants from the material.
