Aluminum die casting is a kind of pressure casting parts. It uses the die casting machine with the casting mold installed. The aluminum or aluminum alloy heated to liquid state is poured into the feeding port of the die casting machine. The aluminum parts or aluminum alloy parts with the shape and size limited by the mold are cast by the die casting machine. Such parts are usually called aluminum die casting. Aluminum die casting has different names in different places, such as aluminum die-casting parts, die-casting aluminum parts, die-casting aluminum parts, aluminum die-casting, aluminum alloy die-casting parts, etc. Due to the good fluidity and plasticity of metal aluminum and aluminum alloy, and the casting process is cast in a pressure die casting machine, aluminum die casting can make a variety of more complex shapes, also can make higher precision and finish, so as to greatly reduce the mechanical processing amount of casting and the casting allowance of metal aluminum or aluminum alloy, which not only saves power and metal materials Aluminum and aluminum alloy have excellent thermal conductivity, small proportion and high machinability; therefore, 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, power construction, architectural decoration and other industries. Aluminum die casting can be manufactured as aluminum die-casting automobile parts, aluminum die-casting automobile engine pipe fittings, aluminum die-casting engine cylinder cylinder, aluminum die-casting gasoline engine cylinder head, aluminum die-casting valve rocker arm, aluminum die-casting valve support, aluminum die-casting power accessories, aluminum die-casting motor end cover, aluminum die-casting housing, aluminum die-casting pump housing, aluminum die-casting building accessories, aluminum die-casting decorative accessories, aluminum die-casting guardrail accessories Aluminum die casting aluminum wheel and other parts. Zhejiang five star power Manufacturing Co., Ltd. was founded in 1997. It is located in the North Industrial Park of Jinhua City, which is located in Shuanglong cave, Jinhua national scenic spot. The traffic is very convenient. The following by the five-star power to introduce the aluminum die-casting process. The four basic processes of die casting aluminum industry are annealing, normalizing, quenching and tempering. These four processes are called "four fires" in die casting. In the process of die casting, the relationship between quenching and tempering is very close, and one of them is indispensable. According to Zhejiang five star power Manufacturing Co., Ltd., annealing is to heat the workpiece. When heated to the appropriate temperature, according to the different materials selected, the die casting parts are slowly cooled, and the internal structure of the metal is close to the balance. Normalizing is to heat the workpiece to a suitable temperature and then cool it in the air. It is mainly used to improve the cutting function of the material, and can also be used for the end die casting of some parts with low demand. Quenching is the rapid cooling in water, or other inorganic salt solution and other quenching media after heating and heat preservation. After this process, the produced steel parts will become hard and brittle at the same time. In order to reduce the brittleness of steel parts, the quenched steel parts can be placed at a temperature below 650 ℃ higher than normal temperature for a long time, and then cooled, which is called tempering. The application of aluminum die casting aluminum material and aluminum alloy have good fluidity and plasticity, so it can make various kinds of complex shape and difficult die casting parts. The casting made of aluminum alloy and metal aluminum has high precision and surface finish, which greatly reduces the machining amount of casting, greatly reduces the labor intensity, and saves power and metal materials 。 Because of its high internal and external quality, aluminum die casting is widely used in automobile manufacturing, internal combustion engine production, motorcycle manufacturing, motor manufacturing, transmission machinery manufacturing, precision instruments, landscaping, power construction, and other industries, becoming a new favorite of die casting industry.

The effects of accelerant, fluoride, Mn2 +, Ni2 +, Zn2 +, PO4; and Fe2 + on the phosphating process of aluminum were studied by means of SEM, XRD, potential time curve and film weight change. The results show that when the concentration of Zn2 + and Zn2 + is low, the film can form dense film; The content of PO4 has a great influence on the weight of phosphating film, which increases PO4. The weight of phosphating film increases with the content of phosphate film. The alkaline electrolytic polishing process of aluminum was studied. The effects of corrosion inhibitor and viscosity agent on the polishing effect were compared. The alkaline solution system with good polishing effect was successfully obtained. The additives which can reduce the operating temperature, prolong the service life of the solution and improve the polishing effect are obtained for the first time. The experimental results show that adding appropriate additives into NaOH solution can produce good polishing effect. The exploratory experiment also found that the reflectivity of aluminum surface can reach 90% after DC constant voltage electrolytic polishing with glucose NaOH solution under certain conditions. However, due to the unstable factors in the experiment, further research is needed. The feasibility of DC pulse electropolishing in alkaline condition is explored. The results show that the leveling effect of DC constant voltage electrolytic polishing can be achieved, but the leveling speed is slow. Environmental friendly chemical polishing of aluminum and aluminum alloy determined to develop a new environmental friendly chemical polishing technology based on phosphoric acid sulfuric acid. The technology should achieve zero emission of NOx and overcome the quality defects of previous similar technologies. The key of the new technology is to add some compounds with special functions in the base solution to replace nitric acid. Therefore, it is necessary to analyze the three acid chemical polishing process of aluminum, especially the role of nitric acid. The main function of nitric acid in aluminum chemical polishing is to inhibit pitting corrosion and improve polishing brightness. Combined with the chemical polishing test in phosphoric acid - sulfuric acid, it is considered that the special material added in phosphoric acid - sulfuric acid should be able to inhibit the point corrosion and slow down the overall corrosion, at the same time, it must have good leveling and bright effect. The process, properties, morphology, composition and structure of ceramic like amorphous composite conversion coating formed by anodic oxidation deposition of aluminum and its alloy in neutral system were studied.

Generally speaking, using aluminum die casting production method, we can be used to manufacture some high-quality auto parts, automobile engine pipe fittings, engine cylinders, or some gasoline engine cylinder head production with aluminum die casting, as well as some valve rocker arm products, valve support products or some electric parts products. And with the development of science and technology, we can use aluminum die casting technology to produce more and more mechanical parts, and ensure the quality of these products is very superior. Do you know what are the main production features of aluminum die casting? If not, I will introduce it in detail. First of all, with the help of aluminum die casting production technology, we can produce some structural shapes The metal parts with complex and clear contour have very thin wall and deep cavity, because if aluminum die casting is used for metal parts production, we need to produce metal parts The raw materials are melted, and then in the working environment to ensure that the molten metal can be under high pressure and high speed, it is possible to produce some special metal parts that can not be produced by other production processes. The die-casting precision of T13 is very small, and some of them can be produced with very small die-casting accuracy and even the surface roughness of T19 can reach very high level.

What is aluminum die casting, as the name implies, is the pressure casting parts. Why is it made of aluminum? It is aluminum that is irrigated at a certain degree. In fact, it is in a certain shape of mold, casting pressure machinery in the use of liquid aluminum or steel pouring, such a process mold is aluminum die casting. Aluminum die casting is widely used in the field of practical engineering, for example, it can become an important part in any complex machinery, and simple mechanical splicing is a common component in a certain range.
