Hydraulic Screen Changer

A Hydraulic Screen Changer is a filtration device installed in plastic extrusion lines to continuously remove contaminants and impurities from molten polymer before it enters the die. The machine uses a hydraulically operated screen assembly to move the filter screen from the contaminated position to a clean position, allowing quick screen replacement with minimal interruption to production.

The hydraulic system provides smooth and controlled screen movement, while the robust construction is designed to withstand high pressure and high temperature conditions commonly found in extrusion processes. The screen changer helps maintain consistent melt pressure, improve product quality, reduce material contamination, and minimize production downtime.

Typical applications:

• Plastic film and sheet extrusion
• Pipe and profile extrusion
• Recycling and compounding lines
• PE, PP, PS, ABS and other thermoplastic processing
• Masterbatch and polymer processing

Key features:

• Hydraulic screen movement
• High-pressure and high-temperature operation
• Quick and reliable screen changing
• Reduced production downtime
• Improved melt filtration and product quality
• Rugged construction for continuous operation
• Suitable for various extrusion capacities and polymer material
