The machine finds extensive application in residential water supply and drainage systems, municipal infrastructure projects, and large-scale agricultural irrigation networks. It employs high-efficiency single-screw extrusion technology coupled with an optimized screw design, ensuring the stable production of PPR pipes with diameters ranging from 75 to 160mm. This equipment features full automation capabilities, operates with energy efficiency, and consistently delivers superior product quality.

Process Flow

PPR resin + color masterbatch → mixing → vacuum feeding → drying → extruder plasticizing (180-210℃) → mold forming → vacuum calibrating → multi-stage spray cooling → laser printing → pull off traction → fixed-length cutting → finished product stacking

Product Parameter

Core components

1. Material Feeding and Drying System	PPR raw materials are automatically conveyed to the extruder's drying hopper via a vacuum feeder to remove moisture, ensuring the moisture content is maintained below 0.1%. This process effectively eliminates bubble defects and guarantees stable product quality to support smooth extrusion operations.
2. PPR Pipe Extruder	Equipped with an SJ75/33 high-efficiency single-screw extruder, the system integrates a 75KW energy-saving servo motor (achieving approximately 20% power consumption reduction), a direct-drive gearbox, a wear-resistant screw barrel made of 38CrMoALA alloy steel (undergoing precision nitriding treatment), an infrared heating coil, and an Omron high-precision temperature control system. These configurations collectively ensure stable material melting, uniform extrusion pressure, and consistent product quality.
3. Marking Line Extruder	An SJ25 extruder is adopted for pipe marking, enabling the configuration of single or multiple marking lines as required by customers.
4. Specialized PPR Pipe Mold	A basket-type or spiral-type die head is employed to realize uniform material extrusion, ensuring consistent pipe wall thickness and structural integrity.
5. Vacuum Calibration Tank	Extruded pipe blanks are subjected to precise calibration through vacuum adsorption (vacuum level 0.06–0.08 MPa). The tank features a food-grade stainless steel structure, equipped with a multi-zone vacuum control system and an efficient water cooling system. It ensures pipe roundness, smooth surface finish, and compliance with dimensional accuracy requirements during high-speed production.
6. Spray Cooling Tank	Adopting multi-stage spray cooling technology, the tank maintains the water temperature below 20°C to achieve rapid and uniform cooling of pipes. Constructed from stainless steel, it possesses excellent corrosion resistance and ensures long-term stable operation.
7. Pull-off Traction Machine	The traction speed ranges from 3 to 15 m/min. Equipped with a precision control system, it maintains stable tension during the traction process, effectively preventing pipe deformation and ensuring dimensional accuracy and uniform length of finished products.
8. Planetary Cutter	It realizes automatic fixed-length and chip-free cutting for small-to-medium-diameter PPR pipes, ensuring smooth and burr-free cutting edges, precise length accuracy, and minimal material waste during production.
9. Laser Printing Machine	It utilizes laser technology for real-time printing of product specifications and batch information, requiring no consumables and ensuring clear and durable marking results.
10. Stacking Rack	It automatically stacks finished pipes in an orderly manner, with adjustable stacking height and layer count. Featuring a robust anti-slip structure, it optimizes storage efficiency and facilitates convenient handling of finished products.
11. Electric Control System	Equipped with high-end electrical components, including ABB frequency converters, Siemens contactors, Omron temperature controllers, and Inovance servo drivers. Optional configurations include a PLC touch screen control system, combined with an intelligent temperature control system and an alarm protection system, ensuring reliable and safe operation of the entire production line..

Product Application

The 75-125mm PPR (random copolymer polypropylene) pipe, an environmentally benign and resilient alternative to traditional galvanized and copper pipes, has achieved widespread adoption. Its core attributes, which encompass a non-toxic and odorless composition, resistance to high temperatures, corrosion, and superior thermal insulation, have propelled it to the forefront as the preferred option in global water supply, drainage, heating systems, and industrial fluid transport sectors.
