If the magnetic product will cause failure after the completion of the CNC die-casting process, many details should be paid attention to during the processing of the CNC die-casting process to avoid the magnetic properties of the CNC die-casting casting shape.

How to solve the magnetic problem of CNC die casting and casting

As we all know, the production of CNC die-casting CNC die-casting processing should not be magnetic, but some products are made of magnetic. Some manufacturers think that the material is the cause, but after the spectral test, the material is not abnormal, many people can't find us. To solve this problem, after discussing the new discovery, we can access a large amount of information and related technicians. CNC die-casting and magnetic cooling are formed because of the internal molding process of CNC die-casting during the cooling process. The structure changes, part of the CNC die-casting process becomes martensite, and the body structure of the CNC die-casting process is magnetic. So why is the CNC die-casting structure transformed into a martensitic structure?

CNC die-casting can be divided into martensitic CNC die-casting and ferritic CNC die-casting according to the structure. CNC die-casting is the largest CNC die-casting process. The CNC die-casting structure is theoretically non-magnetic, but the CNC die-casting process will produce magnetism after cold working. According to some domestic and foreign research, CNC die-casting processing is performed when the CNC die-casting process is heated to the CNC during processing. After the transformation temperature of the die-casting process is higher than the transformation temperature of the CNC die-casting process, the CNC die-casting process is converted into CNC die-casting processing, and then the CNC die-casting process requires cooling and cooling. In this process, when the CNC die-casting process is cooled to the martensite transformation temperature. The tissue begins to become martensite and the transition will not stop until the temperature is below the martensite transformation temperature. In the production of CNC die-casting processing, the stability of CNC die-casting processing, CNC die-casting processing deformation, CNC die-casting processing methods may affect its transformation.

Therefore, according to the cause of the martensite CNC die-casting process and its influencing factors, in order to avoid the production of magnetic materials for CNC die-casting processing, it is necessary to purchase high-CNC die-casting CNC die-casting processing elements when purchasing raw materials. Solid hot melt processing can also be used to eliminate magnetic and work hardening phenomena. Recently, there has been a "demagnetization agent" that can eliminate the magnetic properties of CNC die casting. It can transform the iron element in CNC die-casting into CNC die-casting to achieve degaussing. At the same time, after adding the alloy degaussing agent, the corrosion, salt spray test and the like are good.
