Advanced Continuous Melt Filtration for High-Efficiency Plastic Recycling & Extrusion
The Automatic Screen Changer is a high-performance continuous melt filtration system designed for plastic extrusion, PET/PP recycling, strap production lines, film extrusion, and pipe manufacturing. It provides uninterrupted filtration, full automatic self-cleaning, and stable melt pressure, significantly improving production efficiency while reducing downtime and labor costs.
Key Features & Advantages
1. Continuous Melt Filtration Without Production Interruption
This advanced screen changer ensures nonstop melt filtration during operation. Even while replacing screens, the extrusion line continues running smoothly without shutting down, improving output stability and productivity.
2. 100% Venting Through Precision Venting Grooves
Equipped with specially designed venting grooves, the system fully releases trapped gas during screen replacement, preventing air bubbles, melt instability, and product defects.
3. Four Screen Cavities Design for Maximum Efficiency
The four-cavity structure allows operating and screen changing on the same side, making maintenance easier, safer, and more convenient while saving workspace.
4. 75% Effective Filtration Area During Screen Replacement
Unlike traditional screen changers, 75% of the filtration area remains active even when a new screen is being installed, ensuring continuous filtration performance and stable pressure.
5. 100% Fully Automatic Self-Cleaning System
This machine automatically flushes contaminants from the screen, minimizing manual intervention and reducing labor intensity. It is ideal for high-contamination recycled plastic materials.
6. Long-Life Screen Filter with Up to 100 Repeated Flush Cycles
The durable filtration screen can be repeatedly flushed up to 100 times, significantly lowering consumable costs and increasing operational lifespan.
