The uPVC Profiles window has strong technological performance, and in the molten state, the plastic has high fluidity. Therefore, according to the mold shell, a precise cross-sectional structure can be produced to meet the functional requirements of the dialog box. It can also create a segmented inner cavity to improve the thermal insulation, sound insulation and noise reduction of the window and the function of the drainage pipe, and prevent the corrosion of the steel channel steel of the building.
