Uniform Wall Thickness, Uncompromising Quality — Insights into PVC Pipe Extrusion Line

Ningbo Fangli Technology Co., Ltd. is a mechanical equipment manufacturer with over 30 years’ experiences of plastic pipe extrusion equipment, new environmental protection and new materials equipment. Since its establishment Fangli has been developed based on user’s demands. Through continuous improvement, independent R&D on the core technology and digestion & absorption of advanced technology and other means, we have developed PVC pipe extrusion line, PP-R pipe extrusion line, PE water supply / gas pipe extrusion line, which was recommended by the Chinese Ministry of Construction to replace imported products. We have gained the title of “First-class Brand in Zhejiang Province”.

In the world of plastic pipe manufacturing, efficiency and quality are never a trade-off. As market demands grow and standards tighten, only smarter, more stable, and more energy-efficient production systems can give you the competitive edge you need.

Fangli's PVC pipe extrusion line is built around a PLC intelligent control system, enabling full-line automation with ease of operation and low maintenance. The result? Significantly reduced labor intensity and a marked leap in productivity.

Engineered for Excellence — Core Advantages at a Glance

· Superior Plasticization, Lower Energy Use: Featuring a large L/D ratio parallel twin-screw extruder with a scientifically optimized screw design, our system delivers high output with exceptional plasticization quality — all while keeping energy consumption remarkably low. High productivity and energy savings, now in perfect harmony.

· Precision Tooling for Reliable Forming: Our professionally engineered PVC extrusion dies ensure smooth, balanced melt flow for rapid pipe shaping and consistently high yield rates. Every meter of pipe meets your quality standards.

· Quieter Operation, Greener Performance: With intelligent vacuum pump speed control, noise levels are significantly reduced and energy use is optimized — creating a more comfortable working environment while cutting operating costs.

· Stable Traction, Minimal Scrap: The variable-frequency traction drive offers a wide, stable speed range, effectively minimizing scrap generation and ensuring smooth, uninterrupted production.

· Flexible Upgrades for Future Needs: Optional online belling machines and other automated accessories can be integrated to accommodate various pipe diameters, giving your line the versatility to grow with your business.

· High-Speed Sizing, No Compromises: The sizing sleeve features a pre-cooling design at the inlet, specifically tailored for high-speed extrusion — because speed should never come at the cost of quality.

· Clean Cutting, Hassle-Free Operation: Our fully automatic chip-free cutting system ensures precise, stable cuts, eliminating dust and cleaning concerns for a cleaner, safer workshop.

· Superior Finished Products, Broad Applications: The pipes produced boast uniform wall thickness, smooth inner and outer surfaces, light weight, and outstanding tensile, compressive, and corrosion resistance — quality you can count on.
