There are various techniques for metal forming, each suitable for different types of metals and end products. Some of the most common types of methods include:
Forging
Metal forging is a manufacturing process that involves shaping metal by applying pressure through controlled heating and hammering or pressing, creating a high strength and structurally secure product. Forging includes hot forging, cold forging, closed die forging, open die forging, and more.
Casting
Ideal for complex parts and large volumes, metal casting involves pouring molten metal or liquid metal into a die to obtain the desired shape. Once cooled and solidified, the metal takes the form of the mold. Casting processes include die casting, investment casting, sand casting, and more.
Rolling
Also called roll forming, this metal forming process utilizes rollers to form sheet metal by passing the metal between two rollers. The process typically occurs at elevated temperatures (hot rolling) or room temperature (cold rolling), each offering distinct advantages based on the material properties and intended outcome.
Common Types of Metal Forming Processes
Drawing
Pulling metal through a die to reduce its diameter or change its shape. It involves elongating the metal piece by forcing it through a constricted or shaped orifice, resulting in a thinner and elongated final product. The deep drawing method is often used in making wires, tubes, and other long, slender forms.
Extrusion
Forces metal through a shaped die to produce long pieces with a consistent cross-section. Metal extrusion is commonly used in creating rods, bars, complex structural shapes, and hollow shapes. The Federal Group specializes in aluminum and brass extrusion to satisfy your desired cross section.
Pressing
This metal forming process involves applying pressure to a metal workpiece to form it into a specific shape using mechanical or hydraulic presses. Ideal for smaller runs, metal pressing includes metal bending which uses a machine called a press brake to form sheet metal.
