16-50mm PVC Double Pipe Production Line

The Yongte factory's 16-50mm PVC Double Pipe Production Line is a state-of-the-art, high-performance manufacturing system specifically engineered for the simultaneous and continuous extrusion of two PVC pipes in a single operation, significantly enhancing overall production efficiency and output consistency. This advanced production line incorporates a specially designed conical twin-screw extruder, which is equipped with an optimized screw geometry and enhanced mixing capabilities to ensure thorough and uniform plasticization of various PVC resin types—such as SG-5, UPVC, and CPVC—along with other necessary additives. As a result, it achieves an impressive production speed of 12 to 15 meters per minute for double-cavity PVC pipes within the 16-50mm diameter range. Key advantages of this system include a high degree of automation, exceptional operational efficiency, superior product quality, an ergonomic mechanical structure, notable energy-saving performance, and an intuitive, user-friendly control interface.

Technical Specifications

Product Details and Features

• High-Efficiency Extrusion System	▪ Equipped with a conical twin-screw extruder featuring an optimized screw design, our PVC pipe making machine ensures uniform plasticization of PVC resin (SG-5, UPVC, CPVC) and additives. The screw and barrel are made of high-quality bimetallic alloy and SKD-coated, offering exceptional wear and corrosion resistance.
• Double Cavity PVC Pipe Mold	▪ A specialized extrusion tool designed to produce two PVC pipes simultaneously in a single production line. It features two identical channels (cavities) that allow molten PVC to flow through and form two pipes at the same time.
• Precision Calibrating & Cooling Tank	▪ Integrates a multi-zone vacuum sizing tank and spray cooling system to ensure pipe dimensional accuracy. The tank is fully made of 304 stainless steel.
• Double Cavity PVC Pipe Traction Machine	▪ Equipped with two independent traction cavities (double tracks), the machine pulls two PVC pipes simultaneously with speed synchronization. Each track features an adjustable clamping mechanism (pneumatic/hydraulic options) to apply uniform pressure, preventing pipe slippage, deformation, or length discrepancy between the two pipes.
• Double Cavity Auto PVC Pipe Cutting Machine	▪ Equipped with two independent, synchronized cutting units (one per pipe cavity), the machine executes simultaneous cuts with ultra-high synchronization accuracy. Each unit features a precision-engineered circular saw blade optimized for PVC material to deliver burr-free, flat cuts. The synchronized design guarantees identical pipe lengths (tolerance ±2mm) for both cavities, eliminating waste from mismatched dual pipes and ensuring compliance with ISO/ASTM/GB dimensional standards.
• Electric Control System	▪ Our electrical components utilize internationally renowned high-quality brands, including ABB frequency converters, Siemens or Schneider contactors, Omron temperature controllers, Siemens PLC control system, and Innovance servo motors.
