Automatic Argon Gas Filling Machine for Insulating Glass Units
This Argon Gas Filling Machine for Insulating Glass Units is a professional, intelligent and portable solution for IGU factory production and on site construction. It injects high purity argon into double and multi layer insulating glass to enhance thermal insulation, sound insulation and anti fog performance. Equipped with high precision control modules and multi dimensional safety protection, it enables four unit simultaneous inflation, separate parameter setting and automatic running. It overcomes flaws of conventional inflation tools including low efficiency, imprecise gas supply, gas waste and complicated operation, suiting both large scale factory manufacturing and flexible mobile working scenarios.
High-Precision CNC Arbitrary Angle Welding Machine for PVC
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.
Three Head UPVC Seamless Welding Machine for PVC Window and Door
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.
CNC Double-Head Precision Cutting Saw for 45° & 90°
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.
