The direct shortcomings of aluminum castings are generally caused by incorrect mold and die-casting plans; or unreasonable structural planning of Lian castings, incorrect operation methods, and incorrect casting process conditions; unskilled operators, etc. We should be careful not to purchase defective aluminum castings when purchasing them. Overheating of the mold part will cause cracks. Therefore, the selection of aluminum castings under the same load conditions can reduce the weight of the structure.
In addition, the shock absorber will have noise failure in actual use, which is mainly due to the shock absorber colliding with the leaf spring, the frame or the axle, the rubber pad is damaged or falling off, and the shock absorber dust tube is deformed, and the oil Insufficiency and other reasons should be found out and repaired. is damaged, desoldered, cracked or dropped off.It may be that the oil seal and sealing gasket are damaged and invalid.

Auto Parts-Inspection In order to quickly attenuate the vibration of the frame and the body, and improve the ride comfort and comfort of the car, the car suspension system is generally equipped with shock absorbers, and the two-way-acting...
Frequent use of braking will reduce the braking efficiency of the brake drum, and in severe cases, it will cause brake failure and cause accidents. occur. Fourth, cooling the brake drum For a moving car, as the temperature of the brake drum increases, the braking efficiency will decrease significantly. It is recommended to use premium* brake fluid with high boiling point and not easily deteriorated to greatly improve the driving safety factor.
Therefore, it is an important work for the improvement of the production site to design a good workstation and improve the unsuitable workstation. Conditions, the necessary material conditions will inevitably bring a good working environment to bring higher-quality products and higher profits to the enterprise. The design and improvement of workstation equipment is the requirement of enterprise reform and development. Aluminum alloy machining A good work site cannot be separated from good workstation equipment.
