Twin-column non-stop screen changers maintain constant melt pressure and stable flow rate during screen changing, with no instantaneous flow interruption and no need for re-threading or shutdown for screen replacement.

Advantages of the twin-column non-stop screen changers provided by Zhengzhou Haike:

1. No mechanical seal structure, ensuring no material leakage under high pressure and high temperature. Effectively reduces screen changing resistance and lowers the operating pressure of the hydraulic system.

2. Integrated structure of the column-type screen changer, with no load-bearing gaps, enhancing pressure-bearing capacity for higher system pressure resistance.

3. Made of high-quality alloy steel with nitriding treatment, greatly extending the service life of the product.

4. The twin-column screen changer adopts an integral engineering cylinder for longer service life.

5. Alternating operation mode ensures continuous and stable melt flow and repeatable process parameters during screen changing.

6. Rheologically optimized breaker plate effectively reduces fluid shear during extrusion.

7. Equipped with travel position sensors for more accurate and controllable screen changing.

8. Fitted with safety guards to effectively ensure operator safety, reflecting the people-oriented design concept.

9. Built-in internal heating system for safe and energy-saving operation. Fully enclosed wiring for a neat and professional appearance.
