Induction heat-treating techniques are used extensively in the automotive industry. For 60 years, induction heating has enhanced the manufacturing process for many systems, automotive OEM manufacturers, and Tier 1 suppliers, enabling components to improve.
The process is used for the thermal treatment of parts in assemblies, bearings, brakes, powertrains, gears, joints, and shafts. Induction smelting systems heat wide-range diameter bars and billets for a range of manual and extractive tools, including ubiquitous tools like hammers, wrenches, knives, chisels, drill bits, screwdrivers, and more such as saw blades, shovels, and gears.
Induction heating devices infuse metals, which allows better shaping for engineering parts like automotive axles and shafts. In addition, induction heating coils allow for precise and efficient welding of joints, die hardening, annealing metal surfaces for added flexibility and strength, etc. Face-heating coils can be used for general heating and various brazing applications.
Induction hardening allows parts to be processed on demand and in a manner that does not take hours to complete, unlike alternative thermochemical heat treatment methods.
From a competitive perspective, it makes sense to enable more significant advantages by utilizing the heat-treating technique to improve the metal parts produced.
Many, if not all, suppliers of powertrain parts are doing a portion of their heat-treating in-house, with a mixture of ovens and induction machines used to treat components.
