What are the specifications for precision casting processing

What are the precision casting processing standards
Precision casting processing has excellent forging characteristics. The suitable aluminum alloy and suitable forging method can be determined according to the application purpose, the appearance of the parts, the standard precision, the total number, the product quality standard, the physical performance and other standards and economic benefits. Precision casting is suitable for forging diesel engine cylinder blocks, clutch covers, rear axle housings, steering shaft covers, gearboxes, valve trains, high-pressure oil pumps, centrifugal water pumps, arm covers, car wheels, diesel engine structures, brake calipers , Hydraulic cylinders and brake system discs and other non-diesel engine prefabricated components.
Because there will be a relatively large crystal distribution in the operation process of precision casting, and it has a relatively long period of time to heat and temper this crystal distribution during the forging period, so as to ensure that the production is produced. The finished tea is more ideal, but because the average temperature during the period of melting and proper treatment is closer to the melting point of the low melting point crystallization, therefore, the average temperature must be more convenient to maintain during the period of precision casting processing heating and proper treatment. The heat treatment furnace and related surfaces can be used to detect the average temperature and perform proper conditioning. Only in that way can the actual effect of precision casting parts processing be stronger.
Precision casting processing
Precision casting processing is usually all made of metal casting. According to the different parts, there will be a different total number of sand cores, and the simple features can eliminate the need for sand cores. Precision casting processing is divided into aluminum alloy gravity casting low pressure casting aluminum die casting (high pressure). The sand cores are usually aluminum alloy gravity casting and low pressure casting. High-pressure aluminum die-casting does not allow sand cores. Injection molding has problems in precision casting, and is generally suitable for plastic parts.
Because the compressive strength of the products processed by precision casting is more intimate than the compressive strength of other forging methods. Therefore, its parts will be lighter under the same specifications, and because of this For this reason, its popularity in the sales market at this stage is very high. However, in the selection of castings, it must be determined whether it meets the relevant production standards. There are some defects. If it is fully automatic, then , Such castings must be repaired in the future to be able to invest funds in the production of goods, otherwise it may reduce the service life of all personnel of the goods.
