According to the different temperature, we have cold forging, warm forging and hot forging, just as we have Forging Vs Casting Vs Machining, and SCZY can provide One-stop Forging Service. But now as we talk about the difference between the three types of forgings. OK. Just let us to have a detailed explanation to them. Cold forging is also called cold volume forming. It is a manufacturing process and a processing method. It is basically the same as the cold stamping process. The cold forging process is also composed of three elements: materials, molds, and equipment. It is just that the material in the stamping process is mainly plate, while the material in the cold forging process is mainly a disc or wire. Its Features: high dimensional accuracy, good surface roughness, good working conditions, high production efficiency.

Then here comes to the warm forging: Warm forging refers to forging Steel Forgings below the crystallization temperature and above normal temperature. The purpose of the warm forging process is to obtain precision forgings, and the purpose of warm forging is to improve the precision and quality of the forgings without having the large forming force as cold forging. The application of the warm forging process is closely related to the forging material, the size of the forging, and the complexity of the forging. Its Features: The deformation temperature is strictly controlled, and heating equipment is required. Because the resistance of warm forging is greater than that of hot ballast.
Finally, for the hot forging, it refers to the forging process performed above the metal recrystallization temperature. Its Features: Reduce the deformation resistance of the metal, change the as-cast structure of the steel ingot, and improve the plasticity of the steel. This is particularly important for some high-alloy steels that are brittle and difficult to forge at low temperatures.
