As the brake pads of auto parts are consumables, the brake pads wear more with more driving kilometers. When the wear reaches the critical point, it must be replaced. Generally speaking, under normal driving conditions, we should check the brake pads every 5000 km. In addition to checking the residual thickness, we also need to check the surface wear condition, such as whether there is a difference in the wear degree between the left and right sides, and whether the return is free.

When choosing a seat cushion for auto parts, the first problem is the price. When you buy a seat cushion, you should always have a price in mind and choose to buy it according to your consumption ability. Then there is the problem of style. The car seat cushion you bought should match the style of your favorite car. If the best car seat cushion looks nondescript in the car, it would be better not to put it; The other thing is that the style should not be too fancy. It should be simple and generous to match your car. The second is the specifications of the seat cushions. Now there are many seat cushions in the market that are universal in all seasons. If your car chair is not too small or too large, the universal ones in the market can be used. However, there are also some companies that are producing special car seat cushions, and you can also choose the special ones for your own car.

Valuable technical improvement and technical improvement are mainly reflected in the automatic transportation and automatic transmission device of automobile stamping parts, as well as in the automation of stamping equipment loading and the product oriented stamping production process. The conceptual distinction between traditional stamping and automation is a prerequisite for flexibility of stamping production process and product oriented stamping equipment configuration. The stamping equipment can be distinguished according to the transmission system in the stamping equipment, such as the comparison between the traditional cam driven mechanical transmission and the advanced swing arm transmission. In the traditional cam driven stamping equipment, the control cam of the stamping stroke is designed according to the stamping requirements of the workpiece. No matter how complex the workpiece is, the stamping machine moves according to the specified stroke of the cam, which ultimately leads to the same man hours spent in stamping simple workpieces as in stamping complex workpieces.

60%-70% of metal parts in automobile manufacturing need to be plastically formed. Stamping is an important means to complete metal plastic forming. It is one of the basic, traditional and important metal processing methods. Such as various covers on the body, interior supports, structural reinforcements, and a large number of auto parts, such as engine exhaust elbows and mufflers, hollow camshafts, oil pans, engine brackets, frame structures , transverse beams, etc., are all developed by stamping technology in the direction of precision, multi-functional, high-efficiency, energy-saving, safe and clean production. The manufacturing process level and quality of stamping workpieces have a large impact on the quality and cost of automobile manufacturing. have a direct impact.

The technical requirements of modern automotive stamping parts are developing in the direction of complex structure, increased block size, more components on related sides, increased bearing capacity and strict internal stress restrictions. This requires and promotes the development of special stamping forming technologies such as hydroforming, precision forming, explosive forming, spin forming, dieless forming, laser forming and electromagnetic forming.

Although the welding seam, welding point and repaired steel plate surface of automobile sheet metal parts have been polished and cleaned, there are still numerous minimally invasive and irregular small bumps that are invisible to the naked eye, which are mixed with countless oxides, impurities, water vapor, etc. . Ordinary putty or anti-rust paint has anti-rust function, but it can only prevent the intrusion of external rust and play a temporary sealing role. As long as it is exposed to moisture and other harsh environments, defects will appear quickly. Such as epoxy primer can play an effective protective role.
