How does Dongguan metal stamping parts prevent product damage?

Since the metal stamping parts are damaged to different degrees when the metal stamping parts are produced, what are the good suggestions for preventing or reducing the damage of the metal stamping parts? The following Xiaoshuo summarized a few points: 1) The models, specifications and functions of the selected hardware accessories should conform to the current national standards and relevant regulations, and match the selection of plastic steel doors and windows. 2) Use fastening screws to install hardware. Metal lining plates must be installed inside. The thickness of the lining plates should be at least twice the pitch of the fasteners. It must not be fastened to plastic profiles, and non-metallic linings must not be used. 3) Pay attention to timely maintenance of metal stamping parts after installation to prevent rust and corrosion. 4) The hardware fittings should be installed last, and the door and window locks and handles should be assembled after the window and door leaves are put into the frame to ensure accurate position and flexible opening and closing. 5) For sliding windows with a width of more than 1 meter, or double-glazed doors and windows, double pulleys should be installed, or movable elastic pulleys should be used. 6) The sliding hinge shall not be made of aluminum alloy, but shall be of stainless steel.
