Attention should be paid to maintenance of metal stamping parts after installation to prevent rusting and corrosion. In daily use, it is necessary to close and open gently to prevent damage caused by hard closing and hard opening. There is no noise, there are now nylon wheels. It not only has no noise when pushing and pulling, but also is more smooth and light, and its service life is not shorter than the above various pulleys. To make (door) window normal and smooth operation, it is necessary to select a high-quality pulley for (door) window. Poor quality pulley from the surface, the workmanship is relatively rough. It’s not smooth. It is not flexible to slide, small and light.
Hardware spring piece belongs to the category of hardware stamping parts and electronic hardware data. Selection of stainless steel or manganese material after heat treatment is a primary component of the switch, with the help of the conductivity of metal shrapnel, it plays an excellent switch role between the operator and the commodity. Together, the safe resilience (automatic return after pressing) and super long life span of the pot are used to provide excellent tactile response for operators.
In the production of metal stamping parts, in order to meet the needs of different stamping work, different types of presses are used. There are many types of press, which can be divided into mechanical pressure and hydraulic press according to different transmission modes. Among them, mechanical press is the most widely used in stamping production. With the development of modern stamping technology, high-speed press and CNC rotary head press are widely used.
