The production of iron castings reduces the machining allowance and reduces the cost of mechanical production; it is easy to complete the mechanized automatic assembly line production, and the production line is flexible. Different alloys, different shapes, The production of iron castings of different sizes; the slope of the mold can be extracted; the service life of the applied metal mold can reach more than 100,000 times, which reduces the maintenance cost of the mold. The smoke and noise pollution is reduced, and the labor intensity of the forging workers is reduced; the shape of the parts is not limited by the traditional forging process, so that the mechanical designer can freely design the ideal shape of the cast iron according to the performance of the parts; it can reduce the cost of the cast iron. Net weight, reduce the price of iron castings; the iron casting process is widely used, not only can cast steel and pig iron, but also can cast copper and aluminum. It is suitable for cast copper, cast aluminum, etc.; the cast iron process is not only suitable for cast iron with simple geometry, but also for cast iron with multiple open edges, multiple cores and complex geometry that cannot be started by general forging; Pouring under the vibration state to form a standard alloy composition, which is beneficial to improve the inherent quality of the cast iron.
