PVC pipe extrusion line


Ningbo Fangli Technology Co., Ltd. is a mechanical equipment manufacturer with nearly 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”.



One of the main series of products produced by our company: PVC pipe extrusion line, including four-layer pipe extrusion line, double-layer pipe extrusion line and large-diameter pipe extrusion line. Our company will also provide the basic formula for PVC pipe production, which can be easily adjusted by customers according to the formula. We manufacture machines for producing different PVC pipes, including U-PVC, C-PVC, M-PVC, PVC-O pipes, etc.


Our PVC pipe extrusion line can produce single or multi-layer sizes from a minimum of 16mm to 1000mm.


PVC pipe extrusion line is mainly used to produce pipes for agriculture, building pipes, cable laying and so on. PVC pipe extruder and haul-off unit adopt imported AC frequency conversion speed regulating device, and vacuum pump and traction motor adopt high-quality brands.


Let's understand the components of the extruder production line together. This machine is mainly composed of screw, barrel, heating and cooling, transmission system, head, electrical control box and other parts.


1. Main Machine--Extruder

Targeted screw design: make the plasticization and mixing of materials more ideal, greatly reduce the formulation cost. For the production of high filling formula, the screws imported from Germany are required to be used together with the special treatment of alloy lining to make the equipment more durable.


2. Vaccum Tank

Double pipe design is adopted: it has the function of fast cooling, and will not stop due to accidental pipe blockage during use. Hidden electrical circuit is adopted, which will not cause circuit accidents due to production environment factors. It can also be equipped with a frequency conversion automatic adjustment vacuum system to make the vacuum tank quiet and energy-saving to achieve the purpose of digital control.


3. Haul-off

Haul-off with multi-caterpiller structure: it can make the pipes bear uniform force, not easy to deform, and the traction is stable and reliable. It can achieve stable traction of 20-1000mm pipes. Each traction crawler can be independently controlled and switched to meet the production needs of different pipe diameters. According to different requirements of traction speed, servo click control can be used to make all sides of the pipe receive uniform traction when multiple crawlers work at the same time.


4. Pipe Cutting Machine

Intelligent control cutting machine is adopted: the blade adopts a chip free circular cutting method, which is suitable for cutting small and medium-sized plastic pipes. The cut section is flat and smooth, which can meet the requirements of high-speed cutting. It has the characteristics of long life, low cutting noise and beautiful appearance.
