Castings Are Three Key Elements In Casting Production

The die-casting process is a special process. The quality of the die-casting parts cannot be actually controlled during the die-casting process. All process parameters are only indirect measurements of external control. The true quality of the die-casting parts can only be verified by post-mortem inspection. The quality of the die-casting parts has been formed, and the inspection results cannot change the quality of the die-casting parts. Therefore, in order to ensure the quality of the die-cast products, it is necessary to take the necessary control measures for the die-casting process, such as strictly controlling the stability of the process parameters and the consistency of personnel operations during the die-casting process. However, whether unqualified die castings can be found in time to reduce the loss of waste products as much as possible is particularly important in the production process.

Die-casting parts are three key elements in casting production. The right side of the mold structure is the prerequisite for die-casting production can be carried out smoothly, ensuring the quality of the casting (flat) plays an important role. Due to the characteristics of the die-casting process, the correct selection of process parameters is the decisive factor. In order to obtain the castings and molds, it can correctly select and adjust the process parameters and mold design. In essence, it is a comprehensive reflection and prediction of various factors in die-casting production. If the design of the die-casting parts is reasonable, the problems in the actual production will reduce the high pass rate of the casting plate. On the contrary, the mold design is unreasonable. In the case of a casting design, the dynamic setting mode is at the same wrapping force. Most of them are in the mold pouring system, which cannot be filled in and the perforation is produced in the die casting machine. The normal production cannot be produced. Although the fixed model cavity is very light, because the cavity is deep, it stays in the fixed mold. Therefore, in the mold design, you must fully analyze the structure of the casting, be familiar with the operation process of the die-casting machine, understand the possibility of the die-casting machine, and adjust the technical parameters. The main packaging features under different circumstances, consider the mold processing method, drilling and fixed form , Design a practical mold that meets production requirements. Liquid metal has indicated that the filling time is very short, and the pressure and speed of the liquid metal are very high. This harsh working environment, coupled with the impact of the hot alternating stress of the cold die die, affects the service life of the die.

The mechanical strength and elongation of die-casting alloys are lower than the required standards. The chemical composition of the alloy does not meet the standard. There are air holes, shrink holes and slag inclusions inside the casting. The sample processing methods are not equal. The casting structure is unreasonable, which restricts the casting to reach the standard. Improper smelting process. Exclusion measures The melting of ingredients must strictly control the chemical composition and impurity content. Strictly follow the smelting process. Samples are made as required, and castings are regularly tested in production. Strictly control the melting temperature and pouring temperature of the alloy, and try to eliminate various factors that form the oxide of the alloy. With the continuous improvement of the development level of the domestic manufacturing equipment industry, the equipment level of the die-casting machine has also been significantly improved, the types of parts that can be manufactured are also continuously expanded, and the precision and complexity of the parts that are die-casted have also been greatly improved , I believe that in the near future, die castings will serve our production and life well.
