Window frame and door frame profile extrusion lines are specialized production equipment designed for manufacturing high-quality PVC profiles used in windows and doors. These lines support various profile types, including single-cavity, double-cavity, triple-cavity, and multi-cavity profiles, and can incorporate steel reinforcement to enhance structural strength. High-performance multi-cavity profiles provide superior thermal insulation, wind resistance, and soundproofing, making them ideal for high-rise buildings, cold climates, and noise-prone environments.
These extrusion lines are engineered for efficient production, consistent profile quality, and flexibility, accommodating different profile sizes and complex designs to meet modern architectural requirements.
Window frame extrusion lines include:
1. SJZ series conical twin-screw extruder
2. YF series vacuum calibration table
3. YF series haul-off unit with film wrapping device
4. YF series cutting machine
5. YF series tilting stacker
6. Profile laminating machine (optional)
Note: Door frame profile extrusion lines are similar to window frame lines but often use PVC wood-plastic foam to reduce weight. Screw designs and molds for door frames differ slightly from those used for window frames.
