The working principles of automatic forming machines can vary significantly based on the specific industry and application. Here are some common methods and principles employed in automatic forming machines:

Pressing and Stamping: In industries like metalworking and automotive manufacturing, automatic forming machines use hydraulic or mechanical force to press, punch, or stamp materials into desired shapes. For example, sheet metal can be formed into car body parts using hydraulic presses.

Injection Molding: In the plastic and polymer industries, injection molding machines use a combination of heat and pressure to form intricate parts and components. These machines inject molten material into molds to create products like plastic containers, automotive parts, and consumer electronics.

Extrusion: Extrusion machines heat and force materials, typically plastic or rubber, through a die to create continuous shapes such as pipes, tubing, and profiles used in construction and manufacturing.

Thermoforming: This process is widely used in the packaging and food industry. It involves heating a thermoplastic sheet and forming it into a specific shape using a mold. This is how items like blister packaging and disposable cups are produced.

Rotary Forming: In applications like pharmaceuticals and confectionery, rotary forming machines use a rotating drum or mold to shape materials into tablets, candies, or other similar products.
