Induction forging and induction hot forming

Induction forging and induction hot forming refer to the use of an induction heating machine to pre-heat metals prior to deformation using a press or hammer. Typically metals are heated to between 1,100 and 1,200 °C (2,010 and 2,190 °F) to increase their malleability and aid flow in the forging die. Metal induction forging and induction hot forming are excellent induction heating applications. Industrial forging and hot forming processes involve bending or shaping a metal billet or bloom after it has been heated to a temperature at which its resistance to deformation is weak. Blocks of non-ferrous materials can also be used. Induction heating machines or conventional furnaces are used for the initial heating process. Billets can be transported through the inductor via a pneumatic or hydraulic pusher; pinch roller drive; tractor drive; or walking beam. Non-contact pyrometers are used to measure the billet temperature. Other machines such as mechanical impact presses, bending machines, and hydraulic extrusion presses are used to bend or shape the metal. The approximate hot forming temperatures of the most commonly used industrial materials are: • Steel 1200º C • Brass 750º C • Aluminium 550º C

Total Forming Applications

Induction heating machines are commonly used to heat steel billets, bars, brass blocks, and titanium blocks to the proper temperature for forging and hot forming.

Partial Forming Applications

Induction heating is also used to heat parts such as pipe ends, axle ends, automotive parts, and bar ends for partial forming and forging processes.

The Induction Heating Advantage

When compared to conventional furnaces, induction heating machines for forging offer significant process and quality advantages:

• Much shorter heating times, minimizing scaling and oxidation
• Easy and accurate temperature temperature control. Parts at temperatures outside specifications can be detected and removed
• No time lost waiting for the furnace to ramp up to the required temperature
• Automated induction heating machines require minimal manual labor
• Heat can be directed to one specific point, which is highly important for parts with only one forming area.
• Greater thermal efficiency - heat is generated in the part itself and does not need to be heated in a large chamber.
• Better working conditions. The only heat present in the air is that of the parts themselves. The working conditions are much more pleasant than with a fuel furnace.

Induction Hot forming and Forging Process

Induction Hot forming is a process in the manufacture of industrial fasteners such as bolts, screws and rivets. Heat is used to soften the metal which is usually a sheet, bar, tube or wire and then pressure is used to alter the shape of the metal by performing any of the following operations: hot heading, blanking, punching, slotting, perforating, trimming, shearing or bending. Besides, billet heating is also a process best performed with induction hot forming. SAMSUNG DIGITAL CAMERAModern induction heating provides many advantages over other heating methods and is commonly used for bonding applications. Heating through induction provides reliable, repeatable, non-contact and energy-efficient heat in a minimal amount of time. Induction heating is also ideal for in-line production processes because of its ability to produce repeatable, rapid and accurate heating cycles. Hot Forming and Forging, hot stamping and extrusion consist of forming a part that has been previously heated to a temperature at which its resistance to deformation is weak. The approximate hot forming temperatures of the most commonly used industrial materials are:

• Steel from 1100 to 1250 ºC
• Brass 750 ºC
• Aluminium 550ºC

After heating up the material, the hot forming operation is done on different types of machines: mechanical impact presses, bending machines, hydraulic extrusion presses, etc. The starting material used in forging is presented in the form of rounded studs, squares (billet) or bar materials. Conventional furnaces (gas, fuel) are used to heat the parts but also induction can be used.

Induction heating advantages:

• Material and energy saving plus flexibility
• Greater quality
• Process control
• Much shorter heating times
• Less oxidise and the production of scale is very low
• Easy and accurate adjustment of the temperature to be applied
• No time needed for the furnace pre and maintenance heating (for example after or during the weekend when it takes more time)
• Automation and reduction of the labour required
• Heat can be directed to one specific point, which is highly important for parts with only one forming area
• Greater thermal efficiency
• Better working conditions as the only heat present in the air is that of the parts themselves

The process of forging and hot forming is a common process in the manufacture of many industrial sectors such as automotive, railway, aerospace, oil and gas, chains and forging. https://dw-inductionheater.com/induction-hot-forming-and-forging-process.html?feed_id=235154&_unique_id=65de7a7b05846

• Less oxidise and the production of scale is very low


• Easy and accurate adjustment of the temperature to be applied


• No time needed for the furnace pre and maintenance heating (for example after or during the weekend when it takes more time)


• Automation and reduction of the labour required


• Heat can be directed to one specific point, which is highly important for parts with only one forming area


• Greater thermal efficiency


• Better working conditions as the only heat present in the air is that of the parts themselves

The process of forging and hot forming is a common process in the manufacture of many industrial sectors such as automotive, railway, aerospace, oil and gas, chains and forging.
