Comrise Machinery Co., Ltd.’s PVC Window Profile Machine uses a conical twin-screw extruder, vacuum calibration system, water-cooled shaping platform, haul-off unit, and automatic cutting unit. The line is configured to maintain consistent profile dimensions and surface quality during continuous PVC extrusion. Different line configurations can be selected according to profile design, production requirements, and installation conditions.
1. Conical Twin-Screw Extruder
The conical twin-screw extruder is designed for processing rigid PVC powder and provides stable material plastication and extrusion.
Conical Screw Design: Provides a suitable compression ratio for rigid PVC processing.
High-Torque Gearbox: Supports stable power transmission during continuous extrusion.
2. Calibration Mold Performance
Multi-Block Vacuum Calibration: 2–4 split calibrator blocks with independent vacuum zones help maintain complex chamber shapes during profile forming.
Efficient Cooling Layout: Contour-following cooling channels combined with spray and vacuum cooling help control profile temperature and reduce deformation during shaping.
Stainless Steel Body: Resistant to corrosion from common PVC processing environments and suitable for routine cleaning and maintenance.
3. Water-Cooled Shaping Platform
The water-cooled shaping platform further cools and stabilizes the PVC profile before it enters the downstream equipment.
Extended Length Design: 4 m, 6 m, and 8 m options can be selected according to line configuration and cooling requirements.
Independent Water Circulation Zones: Allow separate control of cooling conditions along the shaping section.
Lifting Mechanism: Facilitates cleaning and routine maintenance.
4. Haul-Off Unit
The haul-off unit pulls the profile at a controlled speed after calibration and cooling.
Pneumatic Pressure Adjustment: Allows the gripping force to be adjusted according to profile thickness and section design.
5. Automatic Cutting Unit
The automatic cutting unit cuts profiles to the required length for downstream fabrication.
Cut Length Accuracy: Helps maintain consistent finished profile lengths.

FAQ
Q1: What types of window profiles can this machine produce?
A: The line can produce frame profiles, sash profiles, casement profiles, T-sections, glazing beads, and accessory trims. Different profile designs require corresponding molds and calibration configurations.
Q2: Can this machine process recycled PVC material?
A: Recycled PVC can be considered when the material is properly processed and matched to the extrusion formulation and equipment configuration. The suitable recycled content should be confirmed according to the material characteristics, profile requirements, and process conditions.
Q3: What information is needed before selecting a PVC Window Profile Machine?
A: The main information includes profile drawings or dimensions, material formulation, required output, target line speed, profile structure, available power supply, and installation conditions. This information helps determine the extruder, mold, calibration, cooling, haul-off, and cutting configuration.
Q4: Do you provide on-site installation and training?
A: Installation and commissioning support can be arranged according to the project requirements. Operator training can cover startup procedures, basic adjustments, routine cleaning, and equipment maintenance. Remote technical support can also be provided where applicable.
Q5: What warranty do you offer?
A: Warranty coverage can be confirmed according to the final equipment configuration and sales agreement. The applicable warranty scope, service terms, and spare parts arrangements should be confirmed before order placement.
Customer Testimonial
"We evaluated three different suppliers before choosing Comrise machinery. Their PVC Window Profile Machine produces the straightest, most consistent window profiles we have ever seen. Commissioning took only 5 days, and our operators were fully trained within a week. The energy savings alone paid for the servo upgrade in under a year."
