      CNC bending machine why use forging?

        With the development of society, China's steel-making technology has reached a certain level. At present, the common processing methods are mainly forging and casting, and the cost of casting is lower than that of forging.CNC bending machine mold is used in the way of forging, many people will wonder why not cast, this article to briefly describe the reasons.CNC bending machineCasting technology in our country has a long history, the overall cost of the workpiece is very low, mainly through the metal smelting into a liquid, and then the liquid poured into a specific mold li, until the liquid metal cooling will form a shaped casting.The casting technique involves burning some steel over a charcoal fire and then rapidly pulling the red-hot steel out into an air-hydraulic hammer for forging.Bending machine blade mouldCNC bending machine die forging rather than casting because casting generally requires the steel mill to produce rolling blank, and the steel mill in the case of a lot of standard parts will be willing to produce, but CNC bending machine die standard parts are generally not a lot, the use of casting is not very cost-effective. CNC bending machine mold for the strength of the requirements is also very high, casting in the production process is easy to produce bubbles lead to the strength is not as good as the forging pieces, forging pieces due to the air hammer forging, internal will be more rigorous, strength will be greater, so CNC bending machine mold generally choose forging rather than casting.
