Casting is one of the main methods for producing rough parts, especially for some brittle metals or alloy materials (such as various cast iron parts, non-ferrous alloy castings, etc.), casting is almost the only processing method. Compared with other processing methods, the casting process has the following characteristics:

Castings are not limited by metal materials, size, and weight. Casting materials can be various cast iron, cast steel, aluminum alloy, copper alloy, magnesium alloy, titanium alloy, zinc alloy, and various special alloy materials; Castings can be as small as a few grams and as large as hundreds of tons; The wall thickness of castings can range from 0.5 millimeters to about 1 meter; The length of castings can range from a few millimeters to over ten meters.

Casting can produce various complex shaped blanks, especially suitable for producing parts with complex inner cavities, such as various boxes, cylinder bodies, blades, impellers, etc.

The shape and size of castings can be very close to the parts, saving both metal materials and cutting time.

4. Castings generally use a wide range of raw materials and have low casting costs.

5. The casting process is flexible, with high productivity, and can be produced manually or mechanically.
