• Conical Twin-Screw Extruder: Equipped with forced fixed-quantity material feeding system, automatic temperature control, vacuum exhaust system, and automatic speed control. Ensures precise material temperature control, plasticization stability, and high production speed. Main motor options include direct converter or frequency converter.
• PVC Extruding Molds: Constructed from high-quality 40Cr material with polished and chrome-plated surfaces. Features multiple head spiral structure for low melt pressure and maintains low temperature even during high-quantity extrusion.
• Vacuum Calibrating Water Tank: Made from high-hardness stainless steel board with high-pressure and corrosion resistance. Two-stage design for large diameter pipes. Features electric water temperature control, ABS engineering plastic nozzles, and three-dimensional adjustable frame with cycloid reducer drive.
• Water Spray Cooling Tank: Stainless steel body with transparent soft PVC curtain. Includes stainless steel float for water level adjustment, electric water temperature control, and ABS engineering plastic nozzles.
• Haul-off Machine: Utilizes frequency conversion approach with chain-driven traction frames for synchronized movement. Features pneumatic flexibility clamping system.
• Cutting Machine: Planetary cutting system for large diameters with rotation and revolution cutting mechanisms. Includes angle cutting structure, pneumatic aluminum half clamping, and cleaning device.
• Control System: Available with Siemens PLC intelligent controlling system or ordinary control system using Siemens electrical parts and Omron temperature controllers. Simple operation interface.
