The difference between forgings and castings

The characteristics of castings are that it is easy to obtain workpieces with complex shapes.The cost of castings is low; precision castings can be obtained by special technology, and the surface has an ideal finish without processing; the forming of castings is simple. Defects and non-dense areas are prone to appear in castings.

Forgings are formed by forging bars using forging equipment. Generally, it is impossible to forge more complex workpieces and require a large amount of processing. However, forgings have a relatively dense structure and are not prone to internal defects, so they are widely used in demanding Component processing, such as valve seat, valve core, valve stem, etc., in high pressure and strong corrosion alloy valves, forged valve bodies are also widely used.
