Induction forging Benefits
Meets tight production tolerances with precise localized heat to small areas creating pinpoint accuracy
Increases production rates with faster heating cycles
Reduces defect rates with repeatable, reliable heat
Eliminates variability from operator-to-operator, shift-to-shift
Maintains metallurgical characteristics of the individual metals
Heating an area around elliptical hole in steel tube prior to forming; the client had been using a torch for this application.
Preheating steel wire before hot heading to create a screw; they wanted to switch from cold heading to extend tool life.
An infrared pyrometer was used to monitor the temperature of the part during the heating cycle. Two parts were tested.
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
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
Testing determined that the magnetic steel rod heated to required temperature within 1.5 seconds with an EASYHEAT LI induction heating system.
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
The client targeted an aggressive cycle time, achieve thanks to our process design and the efficiency of induction heating; fast heating means greater manufacturing throughput
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.
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.
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.
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.
The client targeted an aggressive cycle time, which Ambrell was able to achieve thanks to its process design and the efficiency of induction heating
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
Forging with induction provides increased production rates, repeatable, reliable & consistent heat without flame and hands free heating that involves no operator skill for manufacturing
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.
A four-turn helical coil is used to deliver uniform heat to the inconel billets. Both size billets heat to 2050°F (1121.1ºC) within 12 seconds.
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
