Yongte, a leading professional manufacturer of PPR pipe machine based in China, specializes in high-performance, heavy-duty machine—core equipment for modern plastic pipe manufacturing. Our machines leverage advanced extrusion technology to precisely integrate PPR materials with distinct functional properties, yielding finished pipes with superior mechanical performance, enhanced durability, and diversified application capabilities.
The PPR pipe production line is structurally composed of several key systems: the raw material processing system, extrusion system, mold system, cooling and sizing system, traction system, cutting system, and electrical control system. The raw material processing system is tasked with the pretreatment of various PPR raw materials, such as drying and mixing, to guarantee consistent quality. The extrusion system comprises multiple extruders, each of which is responsible for heating, melting, and extruding a specific type of raw material. The mold system is crucial for co-extrusion, with its runner design dictating the composite effect of the three-layer structure and the shape of the pipe's cross-section. The cooling and sizing system employs a sizing sleeve and cooling water tank to rapidly cool and shape the pipe blank, thereby ensuring dimensional precision and surface quality. The traction system draws the pipe from the mold at a steady speed, controlling both wall thickness and length. The cutting system slices the pipes to predetermined lengths. Lastly, the electrical control system finely tunes temperature, pressure, speed, and other parameters across the entire production line to maintain a stable operation.
The core of Yongte’s PPR pipe machine lies in its synchronized extrusion process: multiple extruders simultaneously melt and plasticize PPR raw materials formulated for different layer functions (inner, middle, outer). These tailored molten materials are then fed into a custom-engineered co-extrusion mold, where they are uniformly compounded to form a three-layer pipe blank. The blank proceeds through a streamlined post-processing workflow—including precision sizing, rapid cooling, constant-speed traction, and automated fixed-length cutting—to produce the final PPR pipe with consistent quality and dimensional accuracy.
1. Raw Material Processing System: Handles pretreatment (drying, mixing, homogenization) of diverse PPR raw materials to eliminate moisture and ensure uniform material consistency—laying the foundation for defect-free pipe production.
2. Extrusion System: The system for multi layer PPR pipe production comprises three extruders, along with their feeding and control systems. One extruder is for the middle layer of PPR plastic pipes, the second for the inner and outer layers, and the third for the pipe's marking line.
3. Electrical Control System: Equip with ABB inverter, Innovance servo motor, Omron temperature controller, Siemens contractors and other high quality electric parts, the control system precisely regulates temperature, pressure, extrusion speed, and traction rate across the entire line. This real-time monitoring and adjustment ensures 24/7 stable operation and minimizes production downtime.
4. PPR Pipe Mold: The custom-designed die head features precision-engineered flow channels that dictate the bonding quality of the three-layer structure and the exact cross-sectional shape of the pipe. Its tailored design guarantees tight layer adhesion and uniform thickness distribution across the pipe wall.
5. Vacuum calibration and Cooling System: Combines a vacuum sizing sleeve and high-efficiency cooling water tank to rapidly cool and shape the pipe blank. This step locks in dimensional accuracy (±0.1mm tolerance) and delivers a smooth, blemish-free surface finish.
5. Meter Counting Encoder: This device works in tandem with the cutting machine to achieve automatic fixed-length cutting of pipes.
6. Traction Machine: We configure caterpillar units according to pipe diameter (e.g., double-caterpillar, triple-caterpillar, four-caterpillar, and fixed-caterpillar types).Pulls the formed pipe from the mold at a constant speed to precisely control wall thickness and overall length—critical for meeting strict industry size standards.
7. Automatic Cutting Machine: Equipped with touch screen programmable control, this dust-free and chip-free cutting machine ensures clean and precise cuts.Automatically cuts pipes to preset lengths (adjustable via touchscreen) with clean, burr-free edges, eliminating post-processing needs.
7. High-Quality PPR Pipes (End Products): Pipes produced by this machine feature smooth inner/outer walls, uniform thickness, and excellent mechanical performance.
In practical production, Yongte’s PPR pipe machine fully leverages the benefits of co-extrusion technology. Our R&D team customizes raw material formulations for different extruders based on market demands, and precisely controls the temperature, pressure and extrusion speed of each extruder to achieve perfect compounding of the three-layer PPR materials in the mold. Factory testing verifies that the produced pipes not only exhibit outstanding physical properties but also reach industry-leading levels in appearance and dimensional accuracy. The mature application of three-layer PPR pipe co-extrusion technology in our production lines provides valuable reference for other manufacturers in the industry.
PPR pipes produced by Yongte’s coextrusion machine boast exquisite appearance and high brand recognition, helping our clients enhance product competitiveness and expand market share.With advanyages of environmentally friendly, durable,non-toxic and odorless composition, high-temperature resistance, corrosion resistance, excellent thermal insulation properties, and easy-to-install, PPR pipes are widely replaced traditional galvanized pipes and copper pipes in global water supply, drainage, heating, and industrial fluid transportation fields.
