After the metal stamping parts are installed, pay attention to maintenance to prevent rust corrosion. In daily use, it should be lightly opened to prevent hard opening and damage. Without noise, there is now a nylon wheel. Not only does it push and pull without noise, but it is smoother and lighter, and its service life is not shorter than the above various pulleys. To make the (door) window run normally and smoothly, we must choose a high-quality pulley for the (door) window. The inferior pulley looks rough on the surface. Not smooth. Sliding is inflexible and light.
　　Hardware springs are attributed to metal stampings and electronic hardware data. The use of stainless steel or manganese material after heat treatment is a primary component of the switch. By virtue of the continuity of the metal shrapnel, it acts as an excellent switch between the operator and the product. Together, we use the stable resilience of the pottery sheet (automatically returning after pressing) and the long life time to provide the operator with excellent tactile feedback.
　　In the production of metal stamping parts, various types of presses are used in order to meet the needs of different stamping jobs. Many types of presses, according to the different transmission methods, can be divided into two major categories of mechanical pressure and hydraulic presses. Among them, mechanical presses are most widely used in stamping production. With the development of modern stamping technology, high-speed presses, numerically-controlled rotary head presses and the like have also been increasingly used.
