As the demand for automobiles continues to increase, the automobile industry is developing by leaps and bounds. Of course, this demand has also promoted the development of the powder metallurgy auto parts industry. Due to the superior performance and relatively low cost of powder metallurgy, powder metallurgy materials are used more and more widely in auto parts.

Application of powder metallurgy parts in automobiles:

Tail door accessories: Whether the car tailgate is manual or electric, the shaft sleeve mainly uses powder metallurgy parts. The shaft sleeve is a cylindrical mechanical part mounted on the rotating shaft and an important part of the sliding bearing. The material must not only have the hardness of the base material, but also require unique cutting and forming. The powder metallurgy parts are stamped and formed at one time without additional cutting to meet the requirements of the ring.

Wiper parts and chassis parts: If the car wiper parts are directly made of plastic and metal materials, they are easy to age in the outdoor environment, while the powder metallurgy parts have good temperature and temperature characteristics , Can be used outdoors. Connecting rods, pendulum connecting rods, bearings, wipers, etc. All wipers are made of powder metallurgy. As a wearing part, the wiper blade must be replaced at the cost of powder metallurgy. Powder metallurgy parts are more suitable. The various sealing covers of the automobile chassis are made of high-strength plastic plates, and the connecting parts of the plastic plates are made of powder metallurgy parts. This is mainly because these parts have a certain degree of hardness. At the same time, due to their relatively high density, they are also affected by external forces. There will be a certain buffering effect.

Interior accessories: Automotive interior accessories use plastic plates and leather. Powder metallurgy parts are mainly used to fix seats and various central control panels. Many powder metallurgy parts have been found in car interiors. High interchangeability, making it invisible in every room.

Compressor parts: In automobile compressors, powder metallurgy parts are used instead of castings. The main reason is that powder metallurgy parts can be mass produced. In terms of dimensional control, the precision is higher, casting can be used at the same time, saving a lot of costs, and the stability of the workpiece is better during use. In compressors, powder metallurgy parts can be used for cylinders, valves, connecting rods, piston rods, crankshafts, etc.
