High-Output HDPE Heat Shrink Sleeve Extrusion Line for Pipeline Anti-Corrosion
The plastic sheet production line is an efficient and energy-saving unit independently developed by our company. It has low energy consumption, high output, and easy operation, and can produce various specifications of PE PP plastic sheets—its core advantages make it worth buying, with key highlights as follows:
Extruder head:
Hanger style flow channel structure, nitriding polishing treatment, special design for easy and precise thickness adjustment operation, ensuring uniform sheet thickness.

Three roll calender:
Precision Roller System Design The roller system features a flexible structural design—vertical for standard widths and oblique for wider applications—ensuring optimal performance across various production requirements. Key Technical Highlights:
Optimized Inner Flow Channel The specially engineered internal flow structure within the rollers enables precise temperature control, ensuring consistent thermal distribution and superior surface brightness of the finished plastic sheet.
High-Precision Mirror Finish Advanced mirror-finished rollers guarantee uniform thickness across a wide range of sheet sizes, minimizing tolerance variations and enhancing product quality.
Durable Hard Chrome Plating The roller surface is coated with hard chromium, providing exceptional wear resistance, high mechanical strength, and extended service life even under continuous operation. Accurate Mold Temperature Control System Integrated with a precision temperature control unit, the system maintains stable processing conditions, delivering consistent high-quality output for demanding production environments.
