The casting alloy is not stable and entrained in gas; The density of aluminum castings is lower than that of cast iron and cast steel, but the specific strength is higher. Casting crack: nonferrous casting parts Manufactures It is a crack formed at a higher temperature. Do not mix organic impurities in the molding sand to reduce the amount of air generated by the modeling materials; Heat exchange equipment used in chemical production, as well as parts that require excellent thermal conductivity on power machinery, such as cylinder heads and pistons of internal combustion engines, are also suitable for aluminum alloys.

After this plan, I combined the theory learned with production practice, trained myself to analyze and solve problems, and laid a solid foundation for future homework and study. If [...]

If there is no oil leakage from the shock absorber, check the bushing Electric vehicle parts Manufactures for damage, desoldering, cracking or falling off. Repair or replacement parts should be carried out. If the car jumps 2 or 3 times, it means that the shock absorber is working well. Otherwise, the shock absorber has failed. Guangxi Auto Parts \u0026mdash;\u0026mdash; Shock absorbers are vulnerable parts in the process of car use.

After determining that the shock absorber is faulty or invalid, first check whether the shock absorber is leaking or has traces of old oil leakage. At this time, you can add appropriate lubricating oil and perform the test again. When the resistance frequency is 100 \u0026 plusmn; 1mm, the resistance of the extension stroke and compression stroke should meet the [...]

Therefore, it is very necessary to improve the design level of work station equipment to make the application of work station equipment in the production process more reasonable and applicable. Prevent parts from knocking, bumping, hurting, dirty and messy in the assembly logistics process, so as to achieve the purpose of ensuring product quality.In the production site management, whether the design of the station equipment is reasonable and applicable to a large extent affects the production site operating environment and the normal logistics of the enterprise. Create conditions for the application of scientific management methods and means.

It is convenient for the assembly workers to take the parts, and the parts do not fall Casting Automotive Mould to the ground during storage, which reduces the invalid labor of the workers [...]

Automobile fuel tank is a container (the country does not manage it as a measuring instrument). The marked volume of the fuel tank is not the actual maximum volume, but the maximum reasonable volume. To fill up the fuel, just add it to the natural jump gun. Therefore, try not to exceed the safety capacity marked on the car manual when refueling, so as not to cause Security risks. In summer, it is easy to expand due to the high temperature.

According to the requirements of relevant national mandatory standards, the rated capacity of automobile fuel tanks should be controlled within The maximum safe capacity of the fuel tank is 95%. Second, it cannot be judged by the fuel gauge on the car dashboard. Most automobile fuel gauges drive electronic sensors [...]
