The first is the design process of castings. When designing, in addition to determining the geometry and size of the casting according to the working conditions and the properties of the metal material, the rationality of the design must also be considered from the perspective of the casting alloy and casting process characteristics, that is, the obvious size effect and solidification and shrinkage. , Stress and other problems to avoid or reduce the occurrence of defects such as segregation, deformation, and cracking of castings.
Second, there must be a reasonable casting process. That is, according to the casting structure, weight and size, casting alloy characteristics and production conditions, select the appropriate parting surface and shape, core making method, and reasonably set the casting rib, cold iron, riser and gating system. To ensure high-quality castings.
The third is the quality of raw materials for casting. The quality of metal charge, refractory materials, fuels, fluxes, modifiers and foundry sand, sand binders, coatings and other materials are substandard, which will cause castings to produce pores, pinholes, slag inclusions, sand sticking and other defects, which will affect the appearance quality of the castings And internal quality, if serious, the casting will be scrapped. The fourth is process operation. It is necessary to formulate reasonable process operation procedures to improve the technical level of workers so that the process regulations can be implemented correctly.
The company is a medium-sized private enterprise integrating casting and machining.
The company is located in Dikeng Village, Dongguan City, Guangdong Province, and was founded in the late 1990s. Through years of technological innovation and reform, as well as the continuous accumulation of talents in casting and processing, we now have a complete machinery manufacturing organization and strong financial strength.
The company’s existing plant area is more than 18,000 square meters, fixed assets of 20 million yuan, hundreds of professional and technical personnel, 4 foundry workshops (lost foam, large parts, machine die, copper and aluminum casting), and 4 processing workshops (CNC, Oil pressure, follow-up, spray painting), sand-finishing products and processed parts can be separated. Externally, from 2009 to 10 years, the annual casting output exceeded 8,000 tons, the processing output exceeded 6,500 tons, and the tax revenue was 10,000 yuan.
