What are the factors that affect the quality of motor housing castings?

With the development of society and technology, the demand for motor housings in the foundry market is increasing, which makes us, as a manufacturer, need to have higher requirements for the quality of motor housings in order to meet customer needs. Next, we will briefly understand which factors affect the quality of the casting of the motor housing. Production practice has proved that the quality of the motor housing mainly includes appearance quality, external quality and application quality. Appearance quality refers to the surface finish, lack of appearance, size deviation, pattern deviation, and weight deviation of the casting; external quality mainly refers to the chemical composition, physical properties, mechanical properties, metallographic organization of the casting, and the holes, cracks, and doping existing in the casting , Segregation and other things; the use of quality refers to the long-term experience of castings under different conditions, covering wear resistance, corrosion resistance, shock resistance to cold and heat, fatigue, shock absorption and other properties, as well as grindability, weldability and other processes performance. 1. Preset craftsmanship of castings. When implementing the preset, in addition to confirming the geometry, size and volume of the casting according to the office conditions and the properties of the metal material, it is also necessary to consider the rationality of the preset from the perspective of the casting alloy and the special properties of the casting process, that is, the surface size Effects and problems such as condensation, shrinkage, stress, etc., to prevent or reduce the initiation of deficiencies such as component segregation, deformation, and cracks in the casting. 2. There must be a reasonable casting process. That is, according to the structure, weight, size and volume of the casting, the special properties of the casting alloy and the production conditions, select the appropriate parting surface and shape, and the core making method, and reasonably set the casting rib, cold iron, riser and gating system. In order to guarantee the acquisition of motor shell castings. 3. The quality of raw materials for casting. The quality of metal charge, refractory materials, combustion materials, fluxes, modifiers, foundry sand, sand binder, paint flakes and other materials does not meet the standards, which will cause the castings to lack vitality holes, pinholes, slag inclusions, and sand sticking. Affect the appearance quality and inner quality of castings, and serious special circumstances make castings discarded. 4. For process operation, it is necessary to formulate reasonable process operating procedures, increase the technical level of workers, and enable accurate implementation of process procedures. The above is the analysis of the factors that affect the quality of the motor housing. I hope you can gain something. Precise, all kinds of motor shells, motor connectors, stretch shells, etc. can be customized, please email us for inquiries.
