Induction Forging

How Does Induction Forging Work?

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

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.

Heating an area around elliptical hole in steel tube prior to forming; the client had been using a torch for this application.

image: Hot Heading Steel Wire: Create ScrewsHot 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.

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

image: Forming a Magnetic Steel PartForming 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

image: Forging a magnetic steel rodForging 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.

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

image: Induction forging rods of various materials and dimensionsInduction 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.

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.

image: Preheating a billet with induction for forgingPreheating a billet with induction 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.

The client targeted an aggressive cycle time, which Ambrell was able to achieve thanks to its process design and the efficiency of induction heating

image: Preheating for forging of steel pinsPreheating 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

Forging with induction provides increased production rates, repeatable, reliable & consistent heat without flame and hands free heating that involves no operator skill for manufacturing

image: Pre Heating Mold Release Push Rod For ForgingPre 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.
