Induction forging is a process where a precisely controlled magnetic field is used to heat metal to be formed into shape using pressure applied by an impact hammer or press. Induction generates an electromagnetic field in a work coil that induces currents in the conductive material of a workpiece placed within or near the coil. Friction from these currents elevates the temperature of the workpiece prior to forging. Can we help? ## Benefits of Forging with Induction A superior and flame-free alternative to furnace heating, induction heating provides faster, more efficient heat in forging applications. The process relies on electrical currents to produce heat within the part that remains confined to precisely targeted areas. High power density means extremely rapid heating, with exacting control over the heated area. ## forging Application Notes Select from our collection of forging notes, developed over 40 years supporting our customers. Read how we helped to solve their process heating challenges! ##### Select an option below: Pre Heating Steel For Forging Tools Heat customer supplied steel bars for a preheat application for forging. Forging a steel rod to stamp saw blade handles The customer-supplied rods were used to design the induction heating coils to deliver energy efficiently using the EKOHEAT system. Hot Heading Steel Wire: Create Screws Preheating steel wire before hot heading to create a screw; they wanted to switch from cold heading to extend tool life. Forming a Large Steel Tube Heating an area around elliptical hole in steel tube prior to forming; the client had been using a torch for this application. Heating Cutting Tools for Forging An infrared pyrometer was used to monitor the temperature of the part during the heating cycle. Two parts were tested. Flattening/Bending Steel Tubes Induction forging elevates the temperature much more rapidly than an oven, targeting the precise portion of the part that requires heating every time, presenting a significant advantage over an oven Forming a Magnetic Steel Part Induction heating drove the part to forming temperature more rapidly than a torch. Induction heating targets the precise portion of the part that requires heating every time Forging a magnetic steel rod Testing determined that the magnetic steel rod heated to required temperature within 1.5 seconds with an EASYHEAT LI induction heating system. Forging silver bars to create collectible coins The client had been using an oven, and forging with induction can present some speed advantages. Unlike an oven, induction heating offers instant on/instant off heating Forging rods of various materials and dimensions Each of the rods were placed into the induction forging coil and heated. They achieved the targeted temperature in 30-40 seconds. The coil was designed for a 5 (127 mm) heat zone. Preheating a brass rod for forging The client wanted to cut the cycle time it was getting from a torch in half, and the Ambrell induction process was able to meet that goal. Preheating a billet for forging The client needed to improve the cycle time of their gas furnace, and by preheating it prior to insertion into the furnace, time was saved and the client didn't have to invest in doubling the size of their furnace. Preheating a brass assembly for forging blanks The client was using a competitor's system, and it was heating the assembly at a slower rate. They needed to increase their production rate, which this solution was able to achieve. Preheating steel rods for forging 1 The client targeted an aggressive cycle time, which Ambrell was able to achieve thanks to its process design and the efficiency of induction heating Preheating for forging of steel pins Fast, precise heating of the pin - 2 minutes and 36 seconds were saved on heating all of the rim's pins when compared to using a torch Preheating titanium rods for forging turbine blades Forging with induction provides increased production rates, repeatable, reliable & consistent heat without flame and hands free heating that involves no operator skill for manufacturing Pre Heating Mold Release Push Rod For Forging To heat the ends of steel rods to 1800 °F using induction prior to a forging operation. Processing of the rods includes heating, pressing in a two part die to forge the push rod end, and a final induction heating in a channel coil to temper the rods and relieve the forging stresses. Pre Heating Steel For Forging Horse Shoes Induction forging provides for hands-free heating that involves no operator skill for manufacturing, improved production rates with minimal defects, low pressure and minimal residual part stress with even distribution of heating Heating Inconel Billets for Forging A four-turn helical coil is used to deliver uniform heat to the inconel billets. Both size billets heat to 2050 °F (1121.1  °C) within 12 seconds. ## forging FAQs You can read our blog post 'Induction Heating for Forging'. Applications where material failure occurs because of cracking would benefit from hot forging. Reduction in press forces are also beneficial using hot forging. Consistent thruput, efficiency of the process and reduced scale formation are a few benefits of induction forging. The induction forging process produces heat within the part, but the heat is generated near the outside surface and will take time to conduct to the center of the part. Typically, bar-ends up to 20 mm in diameter through-heat in less than 10 seconds, whereas a 75 mm diameter bar will take 150 seconds to heat to the center. Hot forging is when a part is heated above the material recrystallization temperature before forging, typically 1100 °C (2012°F). Hot forging allows a part to be formed with less pressure, creating finished parts with reduced residual stress that are easier to machine or heat treat. ## forging Resources * Forging Note Volume Offer * Featured Video * Other Resources ## 18-page induction forging packet We have combined our 'Induction Heating for Forging' brochure and 5 popular application notes to help you understand the many ways induction heating can improve your forging processes.
