In plastic extrusion production, hydraulic screen changers play a crucial role. Their importance cannot be underestimated, as they are key equipment for ensuring the purity and quality of plastic products.

The primary functions of a hydraulic screen changer include:

1. Filtering out foreign particles and impurities from the plastic material flow to ensure the purity of plastic products.

2. Improving overall product quality and reducing defect rates by filtering out impurities.

3. If a hydraulic screen changer is not used, impurities may cause defects, even product interruptions, leading to increased production costs and waste.

Hydraulic screen changers are widely used in processes such as blending and masterbatch recycling, as well as in various fields including sheet production, extrusion, profile production, extrusion, and pipe production.

Their operating principle is based on a hydraulic drive system, featuring a dual-channel design where both screens can operate simultaneously. During screen changes, one screen continues to operate while the other is replaced, ensuring uninterrupted material flow and product production, truly achieving non-stop screen changes.
