PVC Window and Door Profile Extrusion Line

PVC Window and Door Profile Extrusion Line

A high-efficiency, precision-engineered PVC window and door profile extrusion solution designed for modern manufacturing. This system integrates advanced compounding, twin-screw extrusion, vacuum calibration, haul-off, and cutting to deliver stable output, consistent dimensions, and superior surface finish—optimized for scalability, energy efficiency, and low total cost of ownership.

Product Features

Unique Advantages

• High output stability and dimensional accuracy powered by a conical twin-screw extruder (SJSZ65/132) with optimized screw geometry and multi-zone temperature control.
• Consistent material plastication via SRL300/600 high-speed hot-cold mixer, enabling uniform dispersion of additives and colorants.
• Rapid vacuum calibration with hot/cold water separation, delivering faster shaping, reduced shrinkage, and smooth surface finish.
• Intelligent frequency control for main and auxiliary drives (Yaskawa), ensuring precise speed synchronization across feeding, extrusion, haul-off, and cutting.
• Robust PLC + HMI control with modular electrical cabinets for intuitive operation, quick diagnostics, and safer maintenance.

Material Characteristics

• Supports rigid PVC (uPVC) formulations with stabilizers, impact modifiers (e.g., CPE/ASA), and UV/weathering packages.
• Excellent thermal stability, corrosion resistance, and flame retardancy suited for exterior applications.
• Compatible with co-extrusion for gaskets or surface layers; optional embossing/film lamination modules available.

Production Process

• Automated feeding and compounding → twin-screw extrusion and melt homogenization → vacuum calibration and water cooling → synchronized haul-off → precision lift-saw cutting → stack and inspection.
• Closed-loop process control minimizes variation and ensures repeatable quality across batches.

Application Areas

Building & Construction

• Window frames, door frames, mullions, sashes, and glazing beads for residential and commercial facades.
• Exterior trim, cladding profiles, shutters, and decking accessories.
