Forged aluminum alloys are aluminum alloys mainly used for forging processing. Cast aluminum alloy belongs to casting aluminum process, such as die cast aluminum process, sand cast aluminum process, …
To a certain extent, it can improve the planning of the internal gate, so that the flow interval of molten metal in the cavity can be shortened or the cross-sectional area of the gate can be enlarged…
The hot and wet tensile strength of the mold is much lower than that of the wet sand mold. The surface of the mold expands when heated, and the stress concentration and cracks appear in the high wate…
The surface of the casting presents strip-shaped scratch marks along the opening direction, with a certain depth, and it is one-sided when severe. The other is that the liquid metal and the mold weld…
Due to the metal copper, zinc, aluminum and aluminum alloy fittings, now people like to have a little sense of metal, and the die casting has the characteristics of metal, but the process is relative…
In order to reduce the internal cracks of the slab, the mold cooling and secondary cooling section can not be forced cooling, so the optimization of mold water quantity and secondary cooling water ra…
There are many kinds of cast aluminum parts, so it is not necessary to choose silicon aluminum alloy. Even if Si Al alloy is selected, anodizing is not impossible. Generally speaking, the alloy alumi…
In order to improve the surface quality of castings, a coating is often applied on the surface of sand mold and core. The main components of the coating are powder materials and binders with high fir…
Metal casting is to inject molten metal into a hollow mold made of high-temperature resistant materials and condense it to obtain a product of the desired shape. This is casting process. The resul…
Aluminum castings have a series of excellent characteristics such as low density, high specific strength, and corrosion resistance, and will be more widely used in aviation, aerospace, automotive, ma…
In gravity casting, the aluminum alloy gravity casting is believed to be familiar to everyone, because you can learn and master related knowledge through related articles on the website to familiariz…
Aluminum alloy casting is to fill the mold with molten metal to obtain various shapes of aluminum alloy parts. Aluminum alloy casting has the advantages of low density, high specific strength, good c…
The operation of gravity casting is mainly a traditional casting process with sand as the main molding material. Most of its lifting sand molds are made by gravity casting. If there are special requi…
Sand casting mainly refers to the production casting method in the process of operation. Its steel, iron and most nonferrous alloy castings can be obtained by sand casting method. Because the molding…
Gravity casting refers to the process of pouring molten metal into a mold under the action of the gravity of the earth, also known as gravity casting. In the broad sense, gravity casting includes san…
Why sand cast aluminum turn black or white spots?Aluminum alloys are widely used in the foundry industry. Aluminum alloys have good fluidity and plasticity, but they tend to become black or white spo…
