Precision casting processing

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 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, 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 flow of precision castings, and it has a relatively long time during the forging period to heat and temper this crystal distribution, so as to ensure that the production is produced. The finished tea is more ideal. However, because the average temperature during the period of melting and proper treatment is closer to the melting point of the low melting point, it is necessary to choose the average temperature that is easier to maintain during the period of precision casting processing and heating. The heat treatment furnace and the related surface can be used to detect the average temperature and proper conditioning. Only in that way can the actual effect of precision casting parts processing be stronger.
Precision castings are usually all made of metal casting. According to the different parts, there will be a different total number of sand cores. 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 the processing of precision castings, and is generally suitable for plastic parts.
Because the compressive strength of products processed by precision castings is more intimate than those forged by other forging methods. Therefore, its products 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.
