16-50mm Double Cavity PVC Pipe Making Machine

The Yongte factory's durable 16-50mm Double Cavity PVC Pipe Making Machine is a high-performance production apparatus engineered to concurrently fabricate two PVC pipes with superior productivity. It incorporates a conical twin-screw extruder with an enhanced screw configuration, which guarantees consistent plasticization of PVC resin (SG-5, UPVC, CPVC) and various additives. The production rate for 16-50mm double cavity PVC pipes can attain 12-15 meters per minute. The machine exhibits core strengths such as advanced automation, elevated efficiency, exceptional quality, ergonomic mechanical architecture, conservation of energy, and user-friendly operation.

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.

PVC Pipe Applications

Yongte Machine Advantages - humanized mechanical design and durable quality

After years of innovation and quality focus, we use high-strength, wear-resistant materials for plastic pipe machinery. Precision forging and rigorous tests ensure resistance to high-frequency wear and harsh environment erosion.

High torque durable Gearbox	high - efficiency Servo Motor
High-quality vertically direct-connected gearbox: High transmission efficiency, robust load capacity, stable production, space-saving installation, leak-proof sealing, excellent heat dissipation, easy maintenance.	We use Innovance servo motors that save 15-20% power. They provide precise speed and torque control, quick response, low noise and vibration, long life, low maintenance, and intelligent control for stable operation in all conditions.
High automatic operation system	Advanced quality electricity control system
Complete16-50mm Double Cavity PVC Pipe Making Machine: High automation (auto feeding, temperature control, cutting, stacking). Optional automatic material mixing/dosing system for full automation. Servo motor + PLC control (optional speed sync/automatic adjustment).	Equipped with ABB frequency converters, Siemens/Schneider contactors, Omron temperature controllers, and Siemens PLC control system. Cables/connections are well-arranged and clearly marked. Advanced intelligent electrical cabinet enables easy operation, precise parameter adjustment, and custom working modes to boost efficiency.
Strong machine basic made by solid steel plate	Screw barrel are made by wearing material
Machine basic structure: Solid steel plates (CNC-cut/polished for precision/balance, 20+ year durability). 304 stainless steel for rust-proof material/water contact parts.	Bimetallic screws and SKD barrels boost wear resistance and service life, enabling processing of high-abrasiveness materials. Optimized screw geometry enhances melting/mixing efficiency for uniform, high-quality products.
Powder coating for surface finishing treatment	Professional Trial and Installation Service
Post-manufacturing powder coating enhances appearance, anti-rust protection, and color consistency. Electrostatically sprayed thermosetting powder cures at high temperatures to form a dense, scratch-resistant layer. Available in various RAL colors for factory aesthetic matching and long-term durability in harsh industrial environments.	We provide professional trial and installation services to ensure that the machine operates at peak performance. Our experienced technicians conduct on-site trials, adjusting parameters to optimize production efficiency. They also offer comprehensive installation guidance, ensuring seamless integration into your production line.
