Extrusion Screen Changer

Eterlong Extrusion Screen Changer offers a highly economical and efficient solution for blown film extrusion lines. Designed for ease of operation and minimal downtime, it’s an ideal choice for both mono-layer and multi-layer extrusion systems.

Its compact design allows for seamless integration, and an optional adaptor can be installed to connect directly with the Die Head Feeding System. For enhanced process control, the unit also supports the installation of a pressure sensor, enabling real-time monitoring of pressure variations to ensure consistent product quality.

Key Features of Our Extrusion Screen Changer

• Efficient Contaminant Removal
  – Filters out unmelted resin, gels, and impurities to ensure high film quality.
• Improved Extrusion Stability
  – Maintains steady melt pressure and flow, enhancing thickness uniformity and output consistency.
• Reduced Downtime
  – Quick-change design or continuous operation (in dual-piston models) minimizes production interruptions.
• System Protection
  – Prevents clogging and wear in sensitive downstream components like the die head and calibration units.
• Enhanced Material Flexibility
  – Enables the use of lower-cost or recycled materials while preserving end-product integrity.
• Pressure Monitoring
  – Compatible with pressure sensors for advanced process control and safety alerts.
• Easy Integration
  – Compact and adaptable with optional feed adaptors to suit different extruder/die setups.
