What are the characteristics of the hydraulic screen changer:

1. This series of screen changer is composed of filter body, heating/cooling series, electric gas control system and other parts.

2. No need for external force control, the system control elements can automatically control the filtering time and the speed of the net.

3. Automatically and continuously replace the filter screen without human operation.

4. The material flow rate does not fluctuate, the product does not deform, and the quality of the screen changing process is stable.

5. There is no waste and waste, and the consumption of raw materials is low.

6. The length of the filter is 10-20m, and it can be produced continuously for 2-6 months.

7. Applicable raw materials: PP, PE, ABS, PS, PET, HDP, PVC and other plastic melts.

Workers who frequently operate the screen changer know that a test machine is required before the continuous screen changer operation. Many people do not know the test machine process. It is necessary for the test machine to check the quality of the screen changer. Today I will share with you the extruder. Test process of screen changer:

1. There is no need to stop or disassemble the extruder flange to clean up impurities before the perforated plate (also called the manifold), which reduces labor intensity, improves production efficiency, and reduces waste;

2. No need for cooling and heating, thereby reducing power loss;

3. Disassemble the machine without stopping the machine, which improves the production capacity and work efficiency of workers, and increases the efficiency of the enterprise;

4. It is important that the impurities in the melting are filtered through the filter, which improves the quality of the product and intuitively reflects the smoothness of the appearance;

5. By filtering the impurities in the melt, the wear of the mold caused by the impurities is reduced, and the service life of the mold is prolonged;

6. The addition of a screen changing device is equivalent to extending the length of the runner, improving the plasticity and uniformity of the melt, and improving the product quality.
