Our Advantages
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.
3-Roll calender:
Vertical and oblique structures are adopted according to different widths; the specially designed roller inner flow channel structure ensures precise temperature control of the roller and guarantees the surface brightness of the plastic sheet; High precision mirror rollers keep plastic sheet thickness within a wide range with minimal errors; The surface is plated with hard chromium, featuring high strength and long service life, while the precise mold temperature control system provides high-quality assurance for production.
1. Advanced Technology & Stable Operation: Adopt international advanced extrusion and coating technology, with reasonable structure design, ensuring stable equipment operation and a low failure rate.
2. High Automation & Cost Saving: Full-process intelligent operation, greatly reducing manual labor input, saving labor costs, and improving production efficiency.
3. High Anti-Corrosion Quality: Produced heat shrinkable sleeves meet international anti-corrosion standards (ISO, API), with excellent shrinkage rate, tensile strength, and peel strength.
4. One-Stop Turnkey Solution: Provide full-service, including customized design, on-site installation, commissioning, operator training, and solving all production worries for clients.
5. Rich Industry Experience: Share 389+ sets of global project experience, with 9 professional senior engineers and a high-end plastic machinery expert workstation in China.
6. Patented Design & Certified Quality: Own independent patents for equipment design, passed ISO9001, ISO14001, and ISO45001 certifications, ensuring product quality and reliability.
