Pipe Extrusion Making Machine Two Three Layers PPR Automatic Huge Sj65 Water Expanding Tube Extruder Line
Introduction:
Two/Three-Layer PPR Automatic Pipe Extrusion Line – SJ65 Water Expanding Tube Extruder
Our SJ65 Two/Three-Layer PPR Automatic Pipe Extrusion Line is a high-performance, industrial-grade solution designed for manufacturing high-quality multi-layer PPR (Polypropylene Random Copolymer) pipes with precision and efficiency. This advanced extrusion line is specially engineered for producing large-diameter water supply pipes using water expansion technology, ensuring superior strength, durability, and leak-proof performance.
Equipped with automated controls, this extrusion line features twin-screw extruders for stable material processing, a multi-layer co-extrusion system for enhanced pipe structure, and a vacuum calibration & cooling system for dimensional accuracy. The SJ65 model is ideal for producing PPR pipes used in hot/cold water supply, HVAC systems, and industrial fluid transportation, meeting international quality standards.
Extrusion line details:
Raw material + additive → mixing → vacuum feeding machine → hopper dryer → single screw extruder → color code extruder → mould and calibrator → vacuum forming machine → cooling tank → haul off machine → cutting machine → stacker
1. The main machine adopts screws specially used for polyolefin. Equipped with auto vacuum charger and auto constant temperature dryer hopper, it possesses features of high production, good plasticization and stable extruding.
2. Die heads of helical type and basket type are perfect for polyolefin, and can help to produce sound melting pressure, and improve the plasticization capacity. Meanwhile, stable material-flow and pressure grade can be guaranteed.
3. Advanced vacuum calibrating method improves the cleanliness and hardness of surface. Reasonable high-speed sprinkling cooling water tank guarantees the pipe quality and high speed stable extruding.
4. Caterpiller of the hauling machine adopts anti abrassion alloy material, which realizes stable traction, wide frequency adjustment range and long lifespan.
