often hear the word "casting" in life, but it is not clear what is casting and casting. Foundry casting is a type of casting, using sand as raw material. The foundry casting is mostly aluminum alloy, and Hongcheng is also an aluminum foundry factory in Hangzhou.

    the steps of aluminum alloy casting and casting are: prepare the drawing of the product first, make the mold according to the mold, the cost of the mold is generally high, the mold should make the good point, otherwise the product will have a lot of burrs.

    first, make part of the mould, apply the lubricating powder to the surface of the mold, and fill the sand into the mold with a shovel, and step on the mold with force, so that the sand is tread flat and sturdy. And then take part of the mold to make, after finishing, the two molds into one, so that it becomes a complete mold.

    then melt the metal, copper and aluminum into the sand sample.

    when the aluminum water is dry, the sand sample will be opened and the sand around the casting will be removed, so that the appearance of the product will come out. The product that is injected into the metal by sand and mold and other raw materials is called foundry casting.
