1. Material Mixing & Feeding
* PVC resin, stabilizers, and additives are precisely weighed and blended in a high-speed mixer for uniform consistency.
* The mixture is automatically fed into the extruder hopper.
2. Extrusion & Shaping
* The twin-screw extruder melts and compresses the PVC material under controlled temperature.
* Molten PVC is forced through a custom-designed die to form the desired window profile shape.
3. Vacuum Calibration
* Profiles pass through a vacuum calibration tank to ensure precise dimensional accuracy and smooth surfaces.
4. Cooling & Solidification
* A multi-stage water-cooling system rapidly cools the profiles to lock in structural integrity.
5. Pulling & Cutting
* A high-speed puller steadily draws profiles forward.
* An automatic cutting saw trims profiles to preset lengths with ±0.5mm precision.
6. Stacking & Packaging
* Finished profiles are automatically stacked and packaged for storage or shipping.
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.
Stainless steel vacuum table
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.
Haul-off machine.
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.
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.
stacker
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.
