I. Product description

This PVC window profile production line is a fully automated complete set of equipment that integrates mixing, extrusion, calibration, traction, cutting, and stacking. It is specifically designed and manufactured for the production of various types of rigid PVC door and window profiles. The production line adopts a modular design, with full automation control from raw material pretreatment to finished profile output. It can accommodate the production of PVC window profiles with various structures such as casement, sliding, and bridge-cutoff, meeting the customized needs of different building door and window systems.

The core components include a high-speed mixing unit, a conical twin-screw extruder, a vacuum setting table, a crawler-type haul-off machine, a fixed-length cutter, and an automatic stacking rack. The equipment is equipped with a PLC intelligent control system, which enables precise parameter setting, real-time monitoring of the production process, and automatic fault alarming, ensuring stable and efficient operation of the production line.

II. Application Fields

Building door and window manufacturing: Production of bridge-cutoff insulated PVC window profiles, and ordinary sliding/casement PVC window profiles, suitable for residential, office buildings, shopping malls, and other civil and commercial buildings.

Customized door and window processing: Meet customers' personalized needs for profile section size, color, and wall thickness, adapting to the high-end customized door and window market.

Old house renovation project: The produced PVC window profiles exhibit excellent thermal and sound insulation properties, making them suitable for renovation projects of doors and windows in old residential areas.

III. Core Advantages

High efficiency and energy saving, leading in production

The conical twin-screw extruder adopts a special screw design, ensuring uniform and thorough plasticization, with an extrusion efficiency that is 15% to 20% higher than similar equipment. Coupled with a variable frequency speed regulation system, energy consumption is reduced by more than 10%, effectively lowering production costs.

High precision and stable quality of profiles

The vacuum sizing table adopts a multi-stage vacuum adsorption + cooling system, achieving a sizing accuracy of ±0.1mm, ensuring precise profile section dimensions and good straightness. The tractor is driven by a servo system, providing stable traction force to avoid profile deformation, with a finished product rate of over 99%.

Highly intelligent and easy to operate

The entire line is controlled by a centralized PLC system, equipped with a human-machine interface that allows for one-click setting of parameters such as extrusion speed, temperature, and cutting length. It features a fault self-diagnosis function, reducing downtime for maintenance and lowering the skill requirements for operators.

Green and environmentally friendly, meeting standards

The equipment adopts a sealed design to reduce dust and noise pollution; there is no wastewater discharge during the production process, and it is compatible with recycled PVC raw materials, meeting the requirements of national environmental protection and circular economy policies.

Competitive Advantage:

The competitive advantage of the PVC door and window profile production line lies primarily in its comprehensive capabilities, including efficient plasticization and precision molding, intelligent control and stability, low energy consumption, adaptability to recycled materials, and environmental friendliness, as well as custom flexibility and full lifecycle services. These capabilities directly translate into cost advantages, quality advantages, and market responsiveness for customers. The following discussion will focus on five dimensions, highlighting quantifiable values and differentiated barriers.

I. Efficient plasticization and precision molding: leading in both quality and productivity

Core Extrusion System: Utilizing a conical twin screw + barrier/pin mixing section composite screw, the system enhances plasticization uniformity by 20%+ and improves exhaust efficiency by 30%. It effectively removes volatiles and moisture, ensuring stable profile compactness and mechanical properties. Coupled with multi-stage melt filtration (100–150μm) and weight loss metering feeding, the rPVC blending ratio can reach over 40% with a performance retention rate of ≥92%, significantly reducing raw material costs.

Setting and traction accuracy: Multi-segment vacuum adsorption + spray cooling setting table, setting accuracy ±0.1mm, straightness ≤0.3mm/m; servo-driven crawler traction, traction force fluctuation ≤±2%, avoiding profile deformation, yield rate ≥99%.

Capacity and Efficiency: Extrusion output of 120–180kg/h, 15%–20% higher than conventional equipment; adjustable traction speed of 0.5–5m/min, supporting multi-head cutting and continuous production, with a single-line daily capacity increase of 25%+.

II. Intelligent Control and Low-Consumption Stability: Dual Guarantee for Cost Reduction and Operation and Maintenance

Full-process intelligent control: PLC + human-machine interface centralized control, one-click parameter setting, real-time monitoring, fault self-diagnosis and alarm, reducing downtime for maintenance by 30%, and lowering the skill requirements for operators.

Energy-saving design: Optimization of the screw and heating system, achieving a melt conveying efficiency of 92%–95%, with energy consumption reduced by 15%–20% compared to non-standard equipment; variable frequency speed regulation adapts to different formulations and cross-sections, further saving 10%+ in energy.

High reliability and low maintenance: Nitriding on the screw surface / HV900–1100 tungsten carbide coating, increasing wear resistance and service life by 3–5 times; modular design, easy replacement of wear parts, reducing failure rate by 25%–30%.

III. Green Environmental Protection and Renewable Adaptation: Policy and Sustainable Dual Compliance

Environmentally friendly production: The sealed design reduces dust and noise, with no wastewater discharge, meeting the GB/T 19001 and GB/T 24001 systems; it supports efficient processing of recycled PVC raw materials, aligning with circular economy policies.

Low VOC and high quality: Multi-stage exhaust and filtration reduce volatile substances in profiles, meeting EU REACH and domestic green building material standards, and enhancing the added value of end products.

IV. Flexible customization and multi-scenario adaptation: dual flexibility in market and delivery

Multi-type compatibility: Modular configuration allows for quick switching between flat-opening, sliding, bridge-cutoff and other profiles, with a width of ≤200mm and a height of ≤150mm, adapting to different door and window systems.

Customization capability: Supports multi-layer co-extrusion (such as UPVC+PVDF), enhancing strength by 15%, surface hardness by 190%, and anti-aging performance by 230%, meeting the demands of high-end narrow frames.

Rapid delivery and switching: mold change time ≤ 30 minutes, one-click access to recipe parameters, and a 40%+ increase in production efficiency for small batches and multiple batches.
