Metal stamping manufacturers explain to you, the service life of metal molds and mold structure design, mold steel selection, heat treatment, surface treatment, mechanical processing and grinding, wire cutting technology, stamping equipment, stamping materials and processes, mold lubrication, poor maintenance and maintenance, etc. Many factors. Among the various factors that cause mold failure, unfair mold structure, improper material selection accounts for about 25%, improper heat treatment accounts for about 45%, process problems account for about 10%; equipment problems, lubrication problems and other factors account for about 20%. After the installation of the gold stamping parts, we must pay attention to maintenance to prevent rust and corrosion. In daily use, we should gently close and lightly open to prevent hard opening and hard opening, causing damage. The following is an introduction to how to prevent damage to metal stamping parts:
1. The models, specifications and functions of the hardware fittings should conform to the current national standards and relevant demarcations, and be matched with the selection of plastic steel doors and windows.
2. For sliding windows with a width of more than 1 meter, or double-glazed doors and windows, double pulleys should be installed, or dynamic elastic pulleys should be selected.
3. The aluminum alloy material should not be used for the sliding support hinge, and the stainless steel material should be used.
4. The metal stamping manufacturer will explain to you that if you install hardware with fastening screws, a metal lining board must be installed. The thickness of the lining board should be at least greater than twice the pitch of the fastener. It shall not be fastened on plastic profiles, nor shall it be non-metallic lining.
5. The hardware fitting gold should be installed last, and the door and window locks, handles, etc. should be assembled after the window and door fans are in the frame, to ensure accurate position and flexible switch.
6. After installing the metal stamping parts, pay attention to maintenance. The metal stamping manufacturer will explain to you to prevent rust corrosion. In daily use, it is necessary to close and open gently to prevent hard opening and hard opening, causing damage. There is no noise, there is now the nylon wheel. It is not only no noise when pushing and pulling, but also smoother, lighter, and the service life is not shorter than the above various pulleys. To make the (door) window normal. ) Choose a high-quality pulley for the window. The poor-quality pulley looks rough on the surface. It is not smooth. It does not slide smoothly. It is small and light.
