Hardware tells you the three considerations of preventing damage to precision metal stamping parts

The three main considerations for preventing the damage of precision metal stamping parts are as follows: 1. Open when the light is closed every day to prevent hard closing of the hard disk and cause damage. In terms of noiselessness, there are now nylon wheels. It not only pushes and pulls up without noise, and is more smooth, very light, and the service life is not shorter than the above various pulleys. 2. The selection of hardware models, specifications and functions should conform to the current national standards and related establishments, and match the selection of PVC doors and windows. Installation hardware with fastening screws must be equipped with a metal lining, and the thickness of the lining should be twice larger than the fastener pitch. It should not be fastened in plastic profiles or non-metal lining plates. 3. Beware of maintenance after installation of precision metal stamping parts to prevent corrosion of steel bars. Metal parts should be installed with door and window locks, handles, etc. should be assembled into the frame door and window to ensure accurate position and flexibility. The width of the sliding window exceeds 1 meter, or double-glazed doors and windows should be equipped with double pulleys, or choose to move pulleys. The sliding hinge should not be made of aluminum alloy and stainless steel materials should be used.
