Qingdao Yongke Machinery Co., Ltd., a professional manufacturer since 2010, proudly presents our PVC Pipe Extrusion Line Double Screw Extruder – a complete solution for producing high-quality plastic water supply and drainage pipes. This system integrates advanced twin-screw extrusion technology with robust downstream equipment, ensuring stable production, energy efficiency, and consistent pipe dimensions. Whether you need pipes for municipal water supply, underground drainage, or industrial fluid transport, this machine delivers reliable performance with minimal maintenance.
Our double screw extruder is designed specifically for PVC materials, featuring a co-rotating intermeshing screw configuration that provides excellent mixing, plasticizing, and conveying efficiency. The entire line includes a conical twin-screw extruder, vacuum calibration tank, haul-off unit, cutter, and automatic stacker – all tailored to your specific pipe diameter and wall thickness requirements. Backed by our 10,000–30,000 sqm factory and ISO9001/ISO14000/OHSAS18001 certified processes, you can trust this equipment for long-term profitability.
Key Features & Technical Specifications
Double Screw Extruder: Co-rotating twin screws with hardened alloy steel, high wear resistance, and precise temperature control (±1°C).
Pipe Size Range: 20mm to 630mm outer diameter, with wall thickness from 1.5mm to 30mm (customizable upon request).
Output Capacity: From 100 kg/h to 600 kg/h, depending on screw diameter and motor power configuration.
Motor & Drive: Siemens or ABB brand AC motor with frequency inverter for energy saving and smooth speed adjustment.
Vacuum Calibration Tank: Stainless steel construction with multi-stage vacuum pumps for accurate sizing and roundness.
Haul-off Unit: Caterpillar type with servo motor, synchronous belt drive, and automatic tension control to prevent pipe deformation.
Cutting Machine: Hydraulic or planetary cutter for clean, burr-free cuts; length can be preset and automatically adjusted.
Control System: PLC with touch screen (Siemens S7-1200 or equivalent) monitoring all parameters: temperature, pressure, speed, production count.
