Casting refers to a process in which a molten alloy is filled in a mold cavity under high-speed and high-pressure conditions, and a casting having a predetermined shape, size, and performance is obtained by cooling and solidifying and finely processing.
As an advanced non-ferrous alloy precision parts forming technology, castings produced by die-casting usually have many advantages such as precision, light weight, beautiful appearance, energy saving, high efficiency, low consumption, etc., which are suitable for precision, light weight and energy saving in modern manufacturing. Requirements for greening and greening. Therefore, die castings are widely used in many industries such as automobiles, home appliances, electronics, and machinery.
Aluminum alloy die-casting multi-field application is about to break out
Die casting products can be divided into aluminum alloy casting, magnesium alloy casting, zinc alloy casting, copper alloy casting and the like. Among them, aluminum alloy is widely used in household appliances, automobiles, electronic appliances, office equipment, machinery and other accessories because of its light weight, strong wear resistance, high mechanical strength, good heat transfer and electrical conductivity, and high temperature resistance.
Industry barrier
(1) Scale and financial barriers
As a capital-intensive industry, the die-casting industry has a large amount of fixed assets investment, a long construction period, and a long payback period for the initial construction, which requires high investment costs. This requires enterprises to have higher financial strength and invest a large amount of money for building factories and purchasing equipment. In the fierce market competition in the die-casting industry, only companies with strong cost control capabilities, technological R&D capabilities and scale advantages can survive.
(2) Technical and quality barriers
As a technology-intensive industry, the die-casting industry has very strict requirements for molds, die-casting equipment, process and finishing processes in the production of casting products, and downstream customers (such as cleaning appliances and automobile manufacturers) The requirements of material properties, shape, processing precision and weight are also getting higher and higher. This requires that the die-casting enterprise has certain basic material research capabilities, mature casting technology, high mold development and manufacturing level, and can timely target the products. The difference is an effective improvement in the casting process and machining technology.
(3) Market entry barriers
The traditional die-casting industry has disorderly competition, and there are many different small-scale die-casting enterprises on the market. In order to prevent enterprises from blindly building, avoiding disorderly competition in the industry, and curbing the small-scale enterprises entering the industry disorderly, in May 2013, the Ministry of Industry and Information Technology introduced the “Entry Conditions for Foundry Industry”, which was constructed and laid out from the enterprise. The production industry, production equipment, enterprise scale, product quality, energy consumption, environmental protection, occupational health and safety, labor protection, personnel quality and other aspects have established the access conditions for the foundry industry.
Industry extensions
(1) Automotive industry
As the world's largest automobile consumer market, China's car sales are growing steadily while the trend of car lightweighting is also advancing.
On the one hand, as the world's energy problems have become more and more serious in the past 20 years, the fuel consumption of 100 kilometers has become an important reference indicator for the general public to select cars. Reducing the weight of the vehicle body to reduce the reactive power loss has become the consensus of major automobile manufacturers. On the other hand, the battery life of new energy vehicles is one of the main reasons that plague its promotion. Reducing the weight of the vehicle and increasing the cruising range is an important part of enhancing the user experience of new energy vehicles.
Due to its low density and high performance specific gravity, aluminum alloys have significantly reduced the weight of the car body, while at the same time providing outstanding safety performance, which has become a new material for car manufacturers. The proportion of aluminum alloy used in the body is showing a sharp upward trend.
Engine system die casting: engine block, cylinder head, intake pipe, water pump casing, engine casing, starting casing, filter base, engine bracket, engine bracket, distributor base, carburetor, timing sprocket cover, oil Bottom shell.
Transmission system die casting: gearbox housing, clutch housing, connecting filter plate, shift fork, gearbox shift end cover.
Chassis walking system die-casting parts: beam, upper and lower wall, steering casing, brake sub-pump shell, brake caliper, wheel, steering fork, etc.Die castings for other system components: clutch pedals, steering wheel, brake pedal, steering knuckle, engine frame, ABS system components.
At present, in terms of automobile aluminizing rate, China's technology is still relatively backward. At present, the use of aluminum in automobiles in developed countries has reached 180kg, and the aluminizing rate has reached 15%. However, the use of aluminum in China's automobiles is very different from that in foreign countries. The average aluminum consumption is only 60kg, and the aluminumation rate is less than 5%. Therefore, the development prospect of China's automotive aluminum alloy market is very broad.
(2) LED industry
In recent years, China has advocated environmental protection and energy conservation, and has successively issued a series of policies and regulations to support the development of environmental protection industry. Among them, China is actively promoting LED lighting for the LED industry. In 2009, China launched the Ten Cities and Ten Thousand Plans, and later expanded to 50 million in 50 cities.
With the continuous maturity of LED lighting technology, and benefiting from the government's key project procurement, LED streetlight construction continues to promote large-scale and other favorable factors, the demand for LED street lamps continues to rise, greatly stimulating the LED street lighting market.
Usually LED street lights will use suitable die-casting light boxes according to their own size. The die-casting parts used by single LED lamps range from tens of yuan to several hundred yuan. With the continuous promotion of LED street lamps, LED street lamps produced by aluminum alloy die-casting methods are used. Light boxes have great potential for market demand.
(3) Cleaning the electrical industry
With the rapid growth of China's economy, the improvement of people's living standards and the change of young people's clean habits, the demand for the vacuum cleaner market has also increased rapidly, and the overall market has broad prospects for development.
According to statistics, there are about 1 billion people in developed countries and regions around the world. In these countries and regions, an average of 20 horizontal or vertical large vacuum cleaners are purchased every 20 people. The annual average sales volume is about 50 million units. Under the background of the transfer of manufacturing to China, the production of international vacuum cleaners is highly dependent on Chinese companies. It is mainly produced by domestic vacuum cleaners through the OEM/ODM model. China has become a big country in the manufacture and export of vacuum cleaners.
With the development of the entire cleaning electrical industry, vacuum cleaners are constantly optimized and upgraded. At present, in the markets of developed countries and regions such as Europe and the United States, steam cleaners are gradually replacing traditional vacuum cleaners due to their advantages in high-temperature dry steam anti-virus and deep cleaning. As a core component of steam cleaners, there is a strong demand for steam heaters in aluminum alloy die-casting products.
In summary, the aluminum alloy die-casting industry will usher in new development opportunities in the downstream application fields of aluminum alloy die-casting parts to the background of automobiles, LED street lamps and cleaning appliances.
