Cutting Edge Welding Technology
Weather Seal utilizes German made and engineered Stürtz 4-point fusion welder. Stürtz is the leader in providing full system solutions for vinyl window production.
Our Stürtz advanced welding technology allows for sash and frame to be simultaneously fusion welded creating a monolithic box, therefore allowing for a perfect fit between sash and frame.
Since our vinyl window frames are fusion welded, seams never fail, meaning that windows will maintain great energy efficiency for a lifetime.
Glass Cutting Machinery Imported From Europe
Weather Seal uses Italian made Forel “High Tech” IG line evolved from the best of Forel’s latest equipment, mainly dedicated to the production of double and triple insulating glass units for both residential and commercial architecture.
The glass unit manufacturing process is as follows:
The glass sheet enters at first in the Vertical Washing Machine, a special solution with four different processing zones for pre-washing, washing, flushing, drying. The washer is enriched with special sensors to detect the thickness of the glass and the presence of Low-E coating: the independent brushes can adapt the washing to the specific glass thickness and features.
Once washed, the glass sheet arrives to the Inspection and frame positioning Station. This solution allows the operator to easily locate the imperfections, through a special LED light configuration plus movable sliding bars.
The next station is the Coupling Flat Press with Gas Filling, enriched with a patented retractable extra suction cups on the rear side of press. Thanks to this feature, it can flatten also bowed or warped glass, while also improving gas filling and reducing gas waste. The coupling press has a double circuit for argon gas.
The Sealing Robot is the last station of the process: the Sealing Robot offers high productivity thanks to its self-learning technology, the exclusive continuous sealing system and the automatic dosing unit change. Indeed, it can also manage easily non-planar panes, thanks to the nozzle automatic centring.
