Mitre and bevel cutting

Our Two Component Sealant Applicator for Insulating Glass is a high-performance sealing machine designed specifically for the insulating glass and double glazing industry. It is capable of processing two-part sealants including silicone and polysulfide with precise mixing ratios and uniform dispensing pressure. The machine features a static mixing system that eliminates air bubbles, ensuring a strong and durable seal on every IG unit. With PLC-based controls, operators can easily set parameters, monitor performance, and switch between sealant types with minimal downtime. Its modular design allows for straightforward maintenance, while the heavy-duty frame ensures stability during high-speed operation. Whether you are producing standard double glazing units or large-format insulating glass panels, this applicator delivers the accuracy, efficiency, and reliability your production line needs.

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.

This 5-Axis CNC Compound Mitre Saw​ delivers high-precision compound angle cutting for aluminum and UPVC profiles. With CNC servo control and automatic positioning, it ensures ±0.1mm accuracy, smooth cuts, and higher productivity for window, door, and curtain wall production.
