Three considerations for preventing damage to precision metal stamping parts

The three main considerations for preventing the damage of precision 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. To make a normal (door) window. For smooth operation, select high-quality pulleys for the (door) window. On the surface, the inferior pulleys of hardware stamping processing work are rough, not smooth, inflexible in sliding, small and light. 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 at least twice larger than the fastener pitch. It should not be fastened in plastic profiles or using non-metal lining plates. 3. Beware of maintenance after installing metal stamping parts to prevent corrosion of steel bars. The metal parts should be installed at the end, door and window locks, handles and so on should be assembled into the frame door and window to ensure accurate position and flexibility. The width of the sliding window is more than 1 meter, or double-glazed doors and windows should be equipped with double pulleys, or choose to move the pulleys. The sliding hinge should not be made of aluminum alloy and stainless steel materials should be used.
