"August 5" by the original casting machinery manufacturing electromechanical department attaches great importance to investment since the founding of the biggest technological transformation projects and research expenses copper loans to support the development and evolution of foundry machinery industry products. "Large Abrator manufacturing", "vertical parting flaskless shoot squeeze molding machine", "water glass sand sand reclamation equipment development", "metal-casting equipment," and so are successively development applications. Bronze pieces "during the" casting machinery industry and commitment to establish completion of the "efficient car castings refined styling and clean-up technology and complete sets of equipment," the mission car copper pieces, "block the development of efficient continuous blasting lines and clean up Development "is also the success of the processing of copper, and in 1999 successfully completed the national key high level of air impact molding line item. "Fifteen" period, average annual growth of foundry machinery industry of major economic indicators are more than 30 percent, higher than the machine tool industry average growth rate, especially faster profit growth, with an average annual profit growth of 46%, while also keeping higher market levels. In addition, the resin sand molding equipment, could meet the domestic market demand, changes in the past, mainly rely on imports; been able to produce a higher level of casting automatic production line, to be part of the import substitution levels, solve the car engine parts situation cylinder block and head castings have imported rough; a high level automatic core making machines, automatic casting cleaning machines, automatic sand processor, large automatic die-casting machines and casting equipment, casting machinery, basically all domestic manufacturing . It should be said, "fifteen" level during casting machinery industry products has been greatly improved, and lay a good foundation for the future development of Chinese foundry machinery industry further. Is made more economical methods of rough shape, the shape of complex parts can show its economy. Such as automotive engine blocks and heads, ship propellers and exquisite works of art. Somewhat difficult to cut parts, such as gas turbine parts nickel-based alloy can not be formed without casting method. For casting engineers and mechanical design engineers, heat treatment is a very meaningful, but a very high value for ways to improve the material quality, by the heat treatment can alter or affect the organization and the nature of cast iron, and can get higher strength, hardness, and to improve the wear resistance and the like. Since the purpose is different, very much the type of heat treatment, can be mainly divided into two basic categories, the first category is the organizational structure will not change and does not change through the heat treatment or should happen, the second is the basic organizational structure changes by . The first heat treatment procedures, mainly used to eliminate stress, and this stress is due to the different conditions and conditions caused by cooling in the casting process. Organization, strength and other mechanical properties, which does not change significantly due to the heat treatment.
