Casting technology has a long history in our country. The overall cost of the workpiece is very low, mainly by smelting the metal into a liquid, and then pouring the liquid into a specific forming mold. After the liquid metal is cooled, a shaped casting is formed. The casting technology is to burn some steel material in a charcoal fire, and then quickly pull the red steel out and put it into an air hydraulic hammer for forging.
