Advanced PVC Window and Door Profile Extrusion Line

Advanced PVC Window and Door Profile Extrusion Line

Engineered for high-throughput and precision, this PVC window and door profile extrusion line integrates smart compounding, optimized melt processing, rapid cooling, synchronized haul-off, and clean cutting. It delivers consistent geometry, excellent weatherability, and scalable capacity for modern manufacturers seeking competitive uPVC profile production.

Product Features

Distinct Advantages

• Optimized melt homogeneity via advanced screw design and balanced die flow for stable extrusion of uPVC window and door profiles.
• Smart controls with recipe management, auto start/stop sequences, and fault diagnostics to reduce downtime and scrap.
• Quick-change calibration blocks and tooling, shortening product switchovers and improving OEE.
• Low vibration, low-noise drivetrain with energy-saving inverters to minimize operating costs.

Material Properties

• Supports uPVC formulations with lead-free stabilizers, impact modifiers, UV absorbers, and anti-aging packages for exterior durability.
• High dimensional stability, corrosion resistance, and flame-retardant characteristics aligned with building standards.
• Optional co-extrusion layers for sealing carriers, color trim, or wear-resistant surfaces.

Production Workflow

• Metered feeding and dry blend → hot/cold mixing and homogenization → twin-screw melt processing → vacuum calibration and multi-stage cooling → dual-belt haul-off → precision length cutting → inline inspection and stacking.

Application Areas
