● aluminum alloy die casting classification and process

Aluminum alloy die casting classification

Aluminum die-casting can be manufactured as aluminum die-casting auto parts, aluminum die-casting automotive engine parts, aluminum die-casting engine cylinder, aluminum die-casting gasoline engine cylinder cylinder head, aluminum die-casting valve rocker, aluminum die-casting valve bearings, aluminum die-casting power fittings, End die, aluminum die-casting shell, aluminum die-casting pump shell, aluminum die-casting construction accessories, aluminum die-casting decorative parts, aluminum die-casting rails accessories, aluminum die-casting aluminum wheel, and so on.

Stainless steel balls are widely used in non-ferrous metal die casting, casting, aluminum, auto parts, machinery manufacturing, hardware, valve industry, surface treatment. Mainly focused on the product surface oxide scale, the edge of the surface burr, surface roughening, sub-suburban fruit, flattening, rust treatment. Stainless steel shot commonly known as stainless steel wire cut pills, using drawing, cutting, throwing round and other processes refined, the appearance of light without rust, bead-like (cut pill, cylindrical). Stainless steel pills moderate hardness, pure ingredients, large coverage, because there is no general cast steel pills pores, shaped and other shortcomings, its life is longer, the product performance can replace imported products, and the price is significantly lower than the import Products for customers to save costs. After treatment with stainless steel pills, the surface of the casting is not rusty, no need for pickling and other post-treatment, is conducive to environmental protection. You can choose to pre-cast the round cut pills and not pre-cast cut pills, two different shapes of the product.

Process flow

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 heat the workpiece after heating, 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, and other industries , Become the new darling of the die-casting industry
