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…
Low-pressure casting refers to a method in which liquid metal is filled into a mold under a relatively low pressure (0.02 to 0.06 MPa) and crystallized under pressure to form a casting.Centrifugal ca…
Metal casting methods are customarily divided into:Sand casting, die casting, permanent mold casting or gravity casting or Low pressure casting, investment casting or lost wax casting, Centrifugal ca…
The ability of molding sand to resist external force damage is called strength. The molding sand must have high enough strength to not cause collapse during molding, handling, and box closing, and it…
In the process of automobile manufacturing, there are many parts made of cast iron, accounting for about 60% of the whole vehicle weight, such as cylinder block, transmission case, steering gear c…
In our daily life, a lot of parts and articles are directly obtained by casting. In the process of production, gravity casting will effectively have different casting processes according to its diffe…
Sand casting is mainly used to model and core various raw materials when it is used, such as its foundry raw sand, molding sand binder and other auxiliary materials, as well as molding sand, core san…
Casting can also be divided into gravity casting and pressure casting according to the pouring process of molten metal. Gravity casting refers to the process of injecting molten metal into the mold u…
