What Is Metal Forging?
Metal Forging is the process of shaping a piece of metal using continuous pressure, often used to tool steel or iron. The extreme pressure may require rolling, pressing, or hammering the workpiece to shape it into the desired part. Common examples of forged parts include rolled steel bars and beams.
Press forging is one of the most popular processes of metal forging. Instead of hammering or rolling the material, a press is used to shape the part. To compress the material, the press generates significant force. Some presses may use 50,000 tons of pressure.
After forging the part, the new shape has a denser structure, making it stronger and more resilient. Many types of forging exist. The press forging methods are often categorized based on the temperature at which the parts are forged. The main categories include cold forging, warm forging, and hot forging.
Hot Forging vs. Cold Forging
A wide range of metalworking processes is available to forge parts. The type of forging depends on the specifications of the part and the requirements for the production run. Most metal forging involves the use of extreme heat to soften the metal. With hot forging, the metal may be heated up to 2100 degrees Fahrenheit. As the metal is more pliable, less pressure is needed to form the metal.
After pressing the material, it cools and hardens. The finished part is often much stronger compared to its original form. However, hot forging provides less precise tolerances compared to cold forging.
With cold heading manufacturing, the metal is not heated. It is formed near room temperature, which makes it better suited for working with softer metals. The main benefits of cold forging include faster production rates and increased interchangeability.
When deciding between hot forging vs cold forging, it’s essential to consider factors like material properties, desired finish, and production speed to ensure the best results for your project.
