Aluminum Die Casting Process
Aluminum die casting is a kind of pressure casting parts, is the use of casting mold casting pressure casting machine die-casting machine, will be heated to liquid aluminum or aluminum alloy pouring into the die-casting machine inlet, die-casting machine die-casting, casting mold limit The shape and size of aluminum parts or aluminum parts, such parts are usually called aluminum die casting.
Aluminum die casting in different places have different names, such as aluminum die casting parts, die-casting aluminum parts, die-casting aluminum, die-casting aluminum, aluminum die casting, aluminum die casting parts.As the aluminum and aluminum alloy has good flow and plasticity, and casting is casting in a pressure die casting machine, aluminum die casting can make a variety of more complex shapes, but also can make a high degree of accuracy and smoothness , Thus greatly reducing the amount of machined castings and metal aluminum or aluminum alloy casting margin, not only saves electricity, metal materials, but also greatly saves labor costs; and aluminum and aluminum alloy has excellent thermal conductivity, And the high proportionality and high workability; so 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, building decoration and other industry.Here we are introduced to the plant under the aluminum die casting process. Die casting aluminum industry, four kinds of foundation technology are annealing, normalizing, quenching and tempering, the four processes known as die-casting in the "four fire", in the die-casting process, quenching and tempering relationship is very close , Both are indispensable. It is understood that the annealing is to warm the workpiece, when heated to the appropriate temperature, according to the choice of different materials, the die casting slow cooling, has reached the internal structure of metal close to the balance. Normalizing the workpiece is heated to the appropriate temperature and then cooled in the air, mainly used to improve the cutting function of the material, can also be used for some of the need for high parts as the end of die casting. Quenching is to build heat and heat insulation, in the water, or by other inorganic salt solution and other quenching medium in the rapid cooling, after this process, the production of steel will be hardened, but also make steel parts become brittle. In order to reduce the brittleness of steel, the quenched steel can be placed at 650 degrees Celsius below a certain temperature above room temperature for a long time insulation, and then cooling, which is called tempering.The application of aluminum die casting aluminum and aluminum alloy has good flow and plasticity, it can make a variety of complex shapes, the difficulty of die casting, aluminum and metal aluminum casting castings with high accuracy and surface finish , Which greatly reduces the machining of castings, greatly reducing the labor intensity, while saving electricity, metal materials. Because of its high intrinsic quality 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, solar energy and other industries , The new darling of the die-casting industry.
