Casting Used in Industry


We can make all kinds of impeller according to your requirments.


Sand casting is the simplest and most versatile of all casting processes used to produce castings. This process uses wooden or metal patterns that are then placed in the split moulding frame. The frame is then filled with sand and packed around the pattern. The mould is then separated and the pattern removed. Once the mould halves are reassembled, the resulting cavity is filled with the selected molten alloy. There are a variety of types of sand casting, including chemically bonded, clay bonded and oil bonded. The type of sand casting process used is dependent upon production speed requirements, the size of the casting, environmental concerns and cost considerations.
