The Arbitrary Angle Welding Machine for PVC / UPVC Windows is a specialized single-head corner welding solution designed for non-90° and arch window fabrication. It supports continuous angle adjustment from 30° to 180°, enabling precise welding of special-shaped vinyl window and door frames. Equipped with a PLC control system, pneumatic clamping, and an intuitive touch screen interface, it delivers ±0.2mm welding accuracy with stable, repeatable results. Ideal for UPVC manufacturers producing curved, angled, or custom-profile frames beyond standard right-angle joints.
The 3-Head Seamless Welding Machine for PVC / UPVC Doors and Windows is designed for one-cycle welding of three corners (e.g. "┌┬┐" shape) on vinyl window and door frames. Each head integrates heating, pressing, fixing and automatic seam-cutting, so the welded corner is smooth on both surfaces without secondary cleaning—especially suited for co-extruded colored profiles. Three heads can work independently or in combination; one head supports variable-angle (30°–180°) welding for arch windows. Controlled by PLC with touch screen for heating/pressing/cooling time setting, pneumatic clamping ensures repeatable ±0.2mm seam accuracy.
Precision CNC Aluminum Spacer Bending Machine is a high-accuracy automatic equipment designed for bending aluminum spacer bars (6–27mm) into seamless frames for insulating glass units (IGU). Featuring servo-driven feeding, PLC control, and a user-friendly touch screen, it delivers ±0.1mm bending accuracy and supports continuous production of rectangles, triangles, and arches. Ideal for double glazing and IG glass manufacturers seeking efficiency and quality
Designed for precision and reliability, this 2-meter vertical IG washer dryer delivers crystal-clear glass cleaning for insulating glass production. The machine combines three pairs of soft brushes, a stainless steel washing chamber, and an intelligent temperature-controlled drying system. Compatible with Low-E and tempered glass, it integrates seamlessly into any automatic insulating glass line.
This 2m insulating glass washing and assembly line is designed for high-efficiency IGU (Insulating Glass Unit) manufacturing with a maximum processing width of 2000mm. It integrates automatic glass washing, spacer frame placement, and assembly pressing into one continuous production flow. Compatible with Low-E glass and optional argon gas filling, this line delivers reliable performance for double and triple glazing production.
This CNC double-head precision cutting saw is designed for simultaneous 45° mitre and 90° square cutting of aluminum profiles, thermal break aluminum windows, and UPVC/PVC profiles. Equipped with two independent CNC-controlled saw heads, it cuts both ends in one cycle — doubling throughput while ensuring perfect angle matching for corner joints. Features servo-driven length positioning (±0.02 mm repeatability), Ø500–550 mm carbide blades, pneumatic clamping, and a user-friendly 7" touchscreen. Heavy-duty steel frame ensures long-term cutting stability. Ideal for high-volume window, door, and curtain wall fabrication. CE certified, 12-month warranty, global technical support.
