Plastic & Rubber Machinery Parts-Extrusion screen changer

A screen changer is an industrial device used to filter out foreign particles and impurities from molten materials, and is widely used in the melt processing of plastics, rubber, ceramics, and other materials. Below are its main classifications and functional features: I. Hydraulic Screen Changer Utilizes hydraulic drive to move the screen plate or cylinder, offering fast screen-changing speeds (13 seconds) and strong sealing performance. Suitable for high-viscosity materials (e.g., PE, PP, PVC)

What is a single-column screen changer?

A single-column screen changer is a highly efficient filtration device used in the continuous extrusion processes of polymer materials such as plastics, rubber, and synthetic fibers. Its key advantage lies in its ability to perform screen changes without stopping production, effectively ensuring production continuity while improving product quality and equipment utilization. It is suitable for a wide range of continuous extrusion applications. Working Principle of the Single-Column Screen Change

Twin Column Screen Changer for PVC Pelletizing Machinery

In PVC pelletizing production, stable melt filtration and continuous operation are key to high output and consistent quality. A twin column screen changer is the ideal filtration solution for PVC pelletizing machinery, delivering reliable performance under high torque and long production runs. PVC material has unique processing requirements, including sensitivity to temperature and shear force. Our twin column screen changer ensures steady pressure, no material degradation, and zero leakage duri

Single Plate Screen Changer: The Ultimate Solution for Sheet Extruder Efficiency

In the plastic sheet extrusion industry, maintaining consistent production quality while maximizing efficiency is a constant challenge. Contaminants, gels, and unplasticized particles in molten materials often cause defects like pinholes, scratches, and uneven thickness, leading to wasted resources and reduced profitability. The single plate screen changer emerges as a game-changing solution, designed specifically to address these pain points for sheet extruder operations.​ Designed with simplic

Screen Changer for Twin-Screw Extruders

In twin-screw extrusion lines, material compounding is complex, impurities are abundant, and viscosity fluctuates significantly, placing higher demands on filtration and continuous production capabilities. As the mainstream filtration equipment designed for twin-screw extrusion, the twin-column screen changer features a mature design and strong adaptability. It has become a standard core component, offering multiple benefits including filtration, pressure stabilization, and continuous production
