Product Description

Twin-screw PVC window profile extruder

 Our advanced Twin-screw PVC window profile extruder is designed for high-efficiency production of durable and precision-engineered PVC window profiles. The fully automated system integrates cutting-edge technology to ensure consistent quality, energy efficiency, and minimal downtime.

conical twin-screw extruder 

Mould

conical twin-screw extruder is a specialized type of extrusion machinery widely used in polymer processing, compounding, and other industries requiring precise mixing, melting, and shaping of materials. Unlike parallel twin-screw extruders, its screws are designed in a conical (tapered) configuration, with the screw diameter decreasing from the feed zone to the discharge end. 

High Torque Capacity: The conical root diameter provides robust mechanical strength, enabling high torque transmission for processing viscous or filled materials.
Energy Efficiency: Gradual compression reduces peak energy demands compared to parallel screws.
Versatility: Suitable for heat-sensitive materials (e.g., PVC), high-filler composites, and reactive processes (e.g., devolatilization).
Compact Footprint: The tapered design allows for a shorter machine length while maintaining processing capacity.

Die Plate (Die Head):

The core component that shapes the molten PVC into the desired cross-sectional profile.
Made from high-grade tool steel (e.g., H13 or DIN 1.2343) for wear resistance and thermal stability.

Calibration System:

A vacuum calibration unit that cools and solidifies the extruded profile while maintaining dimensional accuracy.
Runner System:

Distributes molten PVC evenly into the die cavity to ensure uniform flow and prevent defects like warping or voids.

The vacuum calibration platform (or vacuum sizing table) is a critical component in PVC window profile extrusion lines, designed to ensure precise dimensional accuracy, surface quality, and structural integrity of extruded PVC profiles.

Dimensional Stabilization:

After exiting the extruder die, the hot, soft PVC profile is pulled into the vacuum calibration platform, where it is rapidly cooled and shaped to its final dimensions.

Vacuum suction forces the molten PVC against the calibration molds, ensuring conformity to tight tolerances (typically ±0.1 mm).

Cooling and Solidification:

Integrated cooling channels (using water or air) solidify the PVC profile, locking in its shape and preventingdeformation.

The haul-off unit (or puller) is a vital component in PVC window profile extrusion lines, responsible for continuously and precisely pulling the extruded and cooled profiles from the die through the calibration and cooling systems. It ensures consistent speed, tension, and alignment, directly impacting the dimensional accuracy, surface quality, and overall productivity of the finished PVC window profiles.

Controlled Pulling Speed:

Maintains synchronization with the extruder's output speed to prevent stretching, compression, or distortion of the profile.
Adjustable speed settings (typically 0.5-6 m/min) accommodate different profile sizes and production requirements.

Tension Management:

Applies uniform tension to the profile to avoid warping, twisting, or surface marks.

Cutter machine

The cutting machine (or sawing unit) is a critical component in PVC window profile extrusion lines, responsible for accurately cutting extruded profiles into predetermined lengths. It ensures precise, clean, and burr-free cuts while maintaining high-speed synchronization with the upstream extrusion and haul-off processes.

This equipment directly impacts production efficiency, material utilization, and final product quality.

Precision Cutting:

Cuts profiles to specified lengths (e.g., standard window frame dimensions) with tight tolerances (typically ±0.5-1 mm).
Ensures squareness and smooth edges for seamless assembly of window systems.
Synchronization:

Operates in tandem with the haul-off unit and extrusion speed to maintain continuous production flow.
Adjusts cutting frequency based on line speed to minimize waste.

The material unloading rack (or discharge table) is an essential component in PVC window profile extrusion lines, designed to efficiently collect, align, and store extruded profiles after they are cut to length. This system ensures orderly stacking of finished profiles, minimizes handling damage, and streamlines downstream processes such as packaging, storage, or transportation.

Orderly Stacking:

Automatically arranges cut PVC profiles into neat stacks, preventing tangling or deformation.
Maintains consistent alignment for ease of handling and subsequent processing.

Buffer Storage:

Acts as a temporary storage buffer between the cutting machine and packaging stations, ensuring continuous production flow.
