Die casting refers to the process of filling the cavity with molten alloy at high speed and high pressure, cooling, solidification and fine machining, in order to obtain castings of predetermined shape, size and performance.
Aluminum alloy die casting manufacturer tell you, as an advanced non-ferrous alloy precision parts forming technology, die casting production castings usually have high precision, light weight, beautiful appearance, energy saving, high efficiency, low consumption and other advantages, applicable to precision, lightweight. Modern manufacturing products energy saving. Greening and greening requirements. Therefore, die casting is widely used in automotive, home appliances, electronics, machinery and many other industries.
Aluminum alloy die casting multi-field application is about to explode
Different raw materials used in die casting. Die casting products can be divided into aluminum alloy castings, magnesium alloy castings, zinc alloy castings, copper alloy castings and other categories. Among them, aluminum alloy is widely used in home appliances, automobiles, electronic appliances, office equipment, machinery and other accessories because of its lightweight material, wear resistance, high mechanical strength, good heat and electrical conductivity, high temperature resistance and other characteristics.
Industry barriers
(1) scale and capital barriers
Die casting industry as a capital-intensive industry, large fixed asset investment, long construction period, the initial construction of a long recovery period, high investment costs. This requires companies to have a high capital strength, in the construction of factories, purchasing equipment to invest a lot of money. In the die-casting industry in the fierce market competition, only have strong cost control ability, technology research and development ability and scale advantage of the enterprise can survive.
(2) Technology and quality barriers
Die casting industry as a technology-intensive industry, in the production process of die casting products on the mold, die casting equipment and process, finishing process have very strict requirements. The material properties, shape, processing accuracy, weight and other requirements are also more and more high, which requires die-casting enterprises have certain basic material research capabilities, mature casting process, high level of mold development and manufacturing, and can target products in a timely manner. This difference effectively improve the casting process and machining technology.
(C) market access barriers
Traditional die-casting industry disorderly competition, good and bad, there are a large number of small die-casting enterprises in the market. In order to prevent blind construction of enterprises, avoid disorderly competition in the industry, curb small enterprises disorderly entry into the industry, in May 2013, the ministry of industry and information technology issued "casting enterprise access conditions" industry ", this is a document from the enterprise construction and layout. , production technology, production equipment, enterprise scale, product quality, energy consumption, environmental protection, occupational health and safety and labor protection, personnel quality and other aspects of the casting industry access conditions.
Extension of the industry's downstream applications
(I) automobile industry
China as the world's largest automobile consumer market, automobile sales are growing steadily, and the trend of automobile lightweight is also advancing.
On the one hand, the global energy problem has become increasingly serious in the past 20 years, the 100 km fuel consumption has become an important reference index of the common candidate car, reduce the body weight to reduce reactive power loss has become the consensus of major automobile manufacturers. On the other hand, the battery range of new energy vehicles is one of the main reasons for its promotion. Reducing body weight and increasing range is an important part of improving the user experience of new energy vehicles.
Aluminum alloy has become a new type of body material promoted by automakers recently due to its low density and high quality performance ratio, which can greatly reduce the weight of the body and at the same time has outstanding safety performance. Aluminum alloy in the body of the proportion of applications in a clear upward trend.
Engine system die castings: engine block, cylinder head, intake pipe, water pump shell, engine shell, starter shell, filter base, engine bracket, engine bracket, distributor seat, carburetor, timing sprocket cover, oil sump.
Transmission system die casting: gearbox shell, clutch shell, connecting filter plate, shift fork, gearbox shift end cover.
