Aluminum stretch forming: thermally broken aluminum windows and doors are the most commonly used aluminum materials, with insulation, thermal insulation, energy-saving and other advantages that are not available in other materials. However, because of its complicated cross-sectional shape, they are prone to wrinkle in the processing of cold bending, thus are likely to affect the appearance of windows and doors.

Beijing Shengda Weiye Bending Company, with more than ten years of work experience, in-depth studies, and continuously explores, has finally successfully solved the problems above. We are able to reach the minimum bending radius of the arc bridge aluminum to R = 260mm, and by cold stretch forming, we are able to bend into an arc shape with straight line segments on the sides, so that the doors and windows look neat, smooth and beautiful.
