Metal forming is commonly performed by applying force to materials such as steel, aluminium, copper, and other metal alloys. Depending on the manufacturing process, metal can be bent, pressed, rolled, drawn, forged, or stamped into a required shape.

Metal forming machinery is used in industries such as automotive manufacturing, construction, aerospace, electronics, agricultural equipment, and general engineering.

For example, vehicle body panels are produced using metal stamping machinery, while structural metal components may be shaped using hydraulic presses and industrial bending equipment.

How Does Metal Forming Technology Work?

Metal forming technology changes a material's shape by applying controlled force. The material generally remains solid during the process, although its dimensions and mechanical properties may change.

The main working principles include:

• Compression: Force is applied to reduce thickness or reshape a metal workpiece.

• Bending: Metal is shaped around a particular angle or curve.

• Tension: Pulling forces stretch metal into a required shape.

• Shearing: Metal sheets or sections are separated through cutting force.

• Drawing: Metal is pulled through a die or into a die cavity to create a specific profile or shape.

The appropriate process depends on material properties, product dimensions, required accuracy, production volume, and the intended application.
