Precision casting and sand casting are two methods in the casting industry, each with its own advantages and disadvantages. The differences between precision casting and sand casting are introduced b…
Operating procedures for sand molding, a common method used in metal casting to create molds for casting various metal objects, involve a series of steps. These steps are designed to ensure the prope…
Aluminum alloy die-casting is a kind of pressure-casting parts. The correct use of aluminum alloy die-casting molds can not only extend the life of aluminum alloy die-casting molds, but also improve …
When it comes to aluminum castings, the quality of aluminum alloy materials and the casting process can affect the appearance of a casting. Aluminum castings do not come down from the production line…
Electroplating is the process of plating a thin layer of other metals or alloys on the surface of aluminum castings using the principle of electrolysis. It is the process of using electrolysis to att…
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…
