Do you know the difference between gravity casting and sand casting?

      Gravity casting and sand casting are both widely used casting methods in the foundry industry. These two casting methods are used in many industries when producing castings. Although many manufacturers use these two methods to produce castings, many people do not know the difference between gravity casting and sand casting used by gravity casting machines to produce castings.

 

       The castings produced by the Gravity Casting Machine have uniform wall thickness, high tissue density, smooth internal and external surfaces, consistent external dimensions, and fast finishing speed. Castings produced by sand casting are prone to slag inclusions, blisters, looseness, rough internal and external surfaces, inconsistent external dimensions, and slow and inaccurate finishing. In terms of yield, the product qualification rate of gravity casting machines is also higher.

 

       The gravity Casting Machine adopts the gravity casting method, which requires low pouring temperature, low pollution and low noise. However, the coal furnace and oil furnace used in sand casting to produce castings produce smoke during the smelting process, which causes high pollution and high noise. Moreover, the operation of the gravity casting machine is simple, and you can learn to operate it. The technology of sand casting requires proficiency to operate, and the cost is also higher than that of gravity casting.
