Stamping parts: The most used in hardware processing refers to the molds for steel/non-ferrous metals and other plates at room temperature, which are formed into a specified shape by the pressure required for processing by a press. Automobile shock absorbers are mainly used to suppress the shock of the spring and the impact from the road surface when the spring rebounds after shock absorption. When passing on uneven roads, although the shock-absorbing spring can filter the vibration of the road, the spring itself will reciprocate, and the car shock absorber is used to suppress the jump of this spring. If the shock absorber is too soft, the body will jump up and down. If the shock absorber is too hard, it will bring too much resistance and prevent the spring from working properly. In the process of modifying the suspension system, the hard shock absorber should be matched with the hard spring, and the hardness of the spring is closely related to the weight of the car. Therefore, heavier cars generally use harder automotive shock absorber stamping parts.

Among them, Donghua Engineering & Technology Co., Ltd., China Chengda Engineering Co., Ltd., Daqing Oilfield Engineering Co., Ltd., Hualu Engineering Technology Co., Ltd., China Tianchen Chemical Engineering Company, Wuhuan Technology Co., Ltd., and Sinopec Shanghai Engineering Co., Ltd. The nine companies of the company, China Chemical Engineering Nanjing Geotechnical Engineering Corporation and Sinopec Ningbo Engineering Co., Ltd. obtained a 3A credit rating; two units of Fuzhou Geological Engineering Exploration Institute of the Ministry of Chemical Industry and Changsha Design and Research Institute of the Ministry of Chemical Industry obtained a 2A credit rating.
According to reports, in the second half of last year, the China Petroleum and Chemicals Survey and Design Association formulated the "Administrative Measures and Implementation Rules for Industry Credit Evaluation," and jointly developed a "Credit Evaluation Index System" in cooperation with China Export Credit Insurance Corporation. The credit rating is divided into three. Grades 5, namely Grade A (3A, 2A, A), Grade B, Grade C; certificates and signs are uniformly designed by the National Regulation Office and the State-owned Assets Supervision and Administration Commission of the State Council, and are uniformly numbered and issued by the China Petroleum and Chemical Survey and Design Association.
Petrochemical survey and design industry announced the first batch of corporate credit rating
Recently, the China Petroleum and Chemical Survey and Design Association announced the industry's first 11 corporate credit ratings. The results of the current credit evaluation have been reported to the National Rectification Office and the State-owned Assets Supervision and Administration Commission of the State Council for the record and published on the China Anti-Commercial Fraud Online.
