How to make low-carbon steel castings produced by lost foam?
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…
Ten major defects of aluminum die castings and prevention...
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…
The new repair technology of casting aluminum parts is to use atomic diffusion between the base metal and the filling material to stick them together.
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…
