What are the specifications for precision casting processing

What are the standards for precision casting production and processing
Precision casting production and 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 production and processing 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, and brakes Non-diesel engine prefabricated components such as calipers, hydraulic cylinders and brake system discs.
Because there will be a relatively large crystal distribution in the operation process of precision casting production and processing, and it has a relatively long time during the forging period to heat and temper this crystal distribution, so as to ensure the production and manufacturing. The finished tea is more ideal. However, because the average temperature during the period of melting and proper processing is closer to the melting point of the low melting point crystallization, therefore, the period of precision casting production and processing heating and proper treatment must be selected for more convenient conditioning. The average temperature of 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 production and processing
Precision casting production and processing are 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 production and 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 production and processing, and is generally suitable for plastic parts.
Because the compressive strength of the products produced 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 one 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.
