Because the temperature of the mold is required in the process of gravity casting, this result will be achieved. Its cooling includes natural cooling and forced cooling. It can also be selected according to different conditions and requirements. of. There are two methods of forced cooling in gravity casting cooling, which should be compressed air cooling and water cooling. If compressed air is used for cooling, the air should also be evenly blown on the surface of the mold. There must be no missing places, otherwise it will affect the service life of the mold, or some other problems such as cracks, deformation, etc. will appear.
The reason for the formation of the porosity of the gravity casting is that the casting is obtained by gravity casting. If there is a problem of porosity, then there may be several reasons: 1. The casting shrinks during the casting process, but there is no Replenish molten metal in time. 2. The cross-section size of the mold or the incorrect position of the inner runner will cause some problems such as local overheating.
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.
