Aluminum die casting parts have different names, such as aluminum die-casting parts, die-casting aluminum parts, die casting aluminum, die casting aluminum, aluminum die casting parts, aluminum die-casting parts and so on. Because the metal aluminium and aluminium alloy has good liquidity and plasticity, and casting processing is in pressure die casting machine casting, aluminum die casting can make all kinds of complicated shape, can also make a higher precision and smooth finish, thus greatly reduced the mechanical processing capacity of the casting and metal of aluminum or aluminum alloy casting allowance, Not only save electricity, metal materials, but also greatly save labor costs; Aluminum and aluminum alloy have excellent thermal conductivity, small specific gravity and high machinability; Thus aluminum die casting is widely used in automobile manufacturing, internal combustion engine production, motorcycle manufacturing, motor manufacturing, oil pump manufacturing, transmission machinery manufacturing, precision instruments, landscaping, electric power construction, architectural decoration and other industries.
China die casting production began in the late 1940s. After decades of development, it has become one of the great countries of production and consumption of die casting in the world. From the perspective of the variety composition of die castings, aluminum alloy die castings and magnesium alloy die castings developed rapidly, with an average annual growth rate of 11.95% and 35.45% respectively from 1995 to 2003. There are nearly 6,000 die casting factories (workshops) of all kinds in China, among which the annual output of more than 1,000 tons accounts for about 12%. Most die casting enterprises are below the annual output of 1,000 tons, and their equipment and technical level are relatively backward. Light alloy die castings such as aluminum alloy are widely used in modern industry, especially in automobiles and motorcycles, communication infrastructure equipment, power tools and other fields. The low-end die casting is in a state of perfect competition, and the competition degree of high-end products such as precision die casting is much smaller than that of low-end products.
With the development of modern industry, various industries have higher and higher requirements on the quality of die castings. The market demand for large, thin-wall and thick-wall die castings which are difficult to produce is also expanding, which promotes the continuous generation of new production technologies, such as vacuum die casting, high-vacuum die casting, ultra-high-speed die casting, ultra-low-speed die casting and so on.
Another important sign of modern industry is the level of automation. International advanced die casting manufacturers can realize automatic production, high production efficiency, stable quality. Most domestic die casting manufacturers have a low level of automation, and a large number of processes need to be processed manually, resulting in poor quality stability. With the market's increasingly high requirements for product quality, some larger domestic manufacturers are gradually improving their automation level, reduce manual operation process, and the gap with the international advanced level is gradually narrowing.
High regional distribution and concentration of china casting enterprises is a major feature of china die casting company . One of the famous is China Beilun die casting, accounting for about 68% of the total number of enterprises. East China, South China, Southwest and Northeast China are the four key regions supporting the development of China die casting manufacturer industry. Their industrial structure is complete, the upstream and downstream markets are unobstructed, the industrial chain is improved, and the industrial scale is developing in the direction of cluster.
Aluminum die-casting parts are widely used, especially in the automotive industry, the demand of aluminum alloy die-casting parts is very considerable, throughout the development of our aluminum alloy die-casting parts, in recent years, the production capacity of aluminum alloy die-casting parts is increasing. According to the statistics of Die Casting Branch of China Casting Association, during the 12th Five-Year Plan period, the production capacity of China's aluminum die casting industry has maintained a growth rate of more than 10%.
In the 12th Five-Year Plan, it has been clearly proposed that China's die casting industry will enter the world mold power in 2020, and win the favor of the world automobile manufacturers with the die casting mold products with high quality, high precision and high life. In light of the goal and the direction of the lead, the die casting industry continuous optimization and upgrading of industrial structure, the adjustment of product structure, mould industry, in particular, more with large, sophisticated, complex, long-life represented by the fastest mold product development of high technical content, beyond the development of the industry's overall speed, occupy about 35% of the total mould, at the same time, The die casting industry is also developing in the direction of information, green manufacturing and sustainable. The branding and internationalization awareness of enterprises are also increasing. The die casting manufacturing industry in China is stepping step by step towards the powerful country of die casting in the world.
