As we all know, copper bar is a solid core copper bar made by extrusion or welding heat treatment. In fact, there are many types of copper bars, such as purple copper bars, brass rods, white copper bars and bronze rods. copper bar molding process can also be regarded as copper bar production and manufacturing process. And different types of copper bar, there will be different forming process. Then the metal forming process is divided into several kinds?

1, metal solidification forming, commonly known as casting.

Forging is a process in which molten metal is poured, shot or sucked into the casting cavity, and the workpiece with certain shape and characteristics is obtained after it condenses.

2, metal plastic deformation forming is the use of metal raw materials have plastic deformation working ability, under the action of the external force to make metal raw materials caused by the expected plastic deformation to get a certain appearance, specifications and physical properties of the parts or blank room production. The process can be divided into free forging, free forging, sheet stamping die, extrusion, suppression and so on.

3. Metal welding forming process.

Electric welding is based on heating or pressure or both and use, and with or without the need to supplement raw materials, so that the metal raw materials do molecular combination of a forming method. The general classification is arc welding, arc welding, fiber welding.

The classification of copper bars can be roughly divided into the above three types according to the molding process of the rods. In addition, there are also very detailed classifications. Due to the wide application scenarios of copper bars, they are also classified according to the application scenarios. The above is about the classification of copper bar, I hope it will be helpful to you.
