Machine Advantages & Client Benefits

Feature	Technical Advantage	Direct Benefit to You
High-Efficiency Extruder	Delivers larger output with stable, consistent performance.	Maximizes productivity and ROI through higher yield and reliable uptime.
Precision Sizing & Control	Produces a pipe wall that is uniform, smooth, and precisely controlled. Thickness is easily adjustable.	Reduces raw material waste and ensures a consistent, high-quality product that meets exact specifications.
Advanced Die Design	No trim edge, once the forming process.	Simplifies operation, eliminates a finishing step, and contributes to material savings.
Integrated Automation	High degree of automation throughout the line.	Saves significantly on labor, as just one operator can efficiently manage costs for the entire line.

High-Efficiency Single Screw Extruder: Features a barrier & mixing head screw combined with a new-model slotted barrel. This advanced design ensures excellent material plasticization, high output, and exceptionally stable performance.

Precision Die-Head: Constructed from polished, chrome-plated components for smooth material flow and corrosion resistance. Features adjustable bolts for uniform wall thickness control and an integrated copper calibrating sleeve for simultaneous pipe cooling and outer diameter sizing.

Vacuum Calibration Tank: A stainless steel tank integrating a vacuum system and multi-directional spray cooling. It creates negative pressure to size the pipe's outer diameter against the calibrating sleeve and rapidly quenches the pipe with water spray for immediate dimensional stabilization.
