Induction Heat Treating

What Induction Heat Treating does

Induction Heat Treating Corporation (IHT), founded in 1990 and headquartered in a 35,000 sq ft facility in Crystal Lake, Illinois, is a privately held commercial heat treater serving automotive, heavy equipment, and industrial customers from three Midwest plants — Crystal Lake, IL; Waukesha, WI; and Seymour, IN. The company provides induction heat treating services including hardening, case hardening, tempering, and annealing, supported by in-house coil and tooling design and value-added offerings such as glass bead blasting and magnetic particle inspection. Its technical platform spans induction power supplies from 15 kW to 400 kW and frequencies from 1 kHz to 450 kHz, with zero-gravity hoist handling, Fanuc multi-axis robotic work cells developed in partnership with Induction Systems, Inc., and sensor-controlled automation that includes pocket depth sensing, energy monitoring, auto accept/reject sorting, and self-controlled cooling.

IHT operates an asset-heavy, capacity-utilization-driven business model: customers ship parts to IHT's plants where revenue is generated per processed part, with profitability tied to capital utilization across three shifts, five days per week, and to the maintenance of OEM-specific tooling, process windows, and certifications (ISO 9001:2015, CQI-9). The customer mix spans small job-shop volumes through Fortune 500 OEMs including Ford, Caterpillar, Chrysler, John Deere, TRW, Case New Holland, Regal Beloit, and General Dynamics. Commercial heat treating is a qualification-intensive business in which switching costs are created by part-specific tooling, validated process parameters, and PPAP-level documentation, locking customers in once a part is qualified.

Technically, IHT differentiates through the depth of its metallurgical bench — including Richard E. Haimbaugh, author of the industry reference "Practical Induction Heat Treating" — and its recognition as a two-time "Commercial Heat Treater of the Year" awardee. The company supplements core induction processing with an expanded Quality Lab (480 sq ft, 1000x microscopy) for failure analysis, metallography, and customer-facing documentation required by automotive and aerospace supply chains. Multi-site Midwest positioning is a deliberate logistics play: it shortens freight lanes to the Detroit Three, the Midwest heavy-truck and agricultural-equipment cluster, and defense primes, supporting just-in-time delivery for high-mix, low-volume runs that smaller job shops cannot economically serve.

Functional benefit

Products and services

• Induction Hardening Selective heat treating process that hardens specific areas of metal components using electromagnetic induction, suited for industrial manufacturers requiring wear resistance on targeted part surfaces.
• Induction Case Hardening Surface hardening service that creates a hardened outer case on steel components while maintaining a tougher core, used for gears, shafts, and other wear-critical parts.
• Induction Tempering Post-hardening heat treatment performed at lower temperatures to reduce brittleness and achieve desired hardness and toughness balance in metal parts.
• Induction Annealing Heat treating process that softens metals, relieves internal stresses, and improves machinability or formability of components.
• Custom Coils and Tooling In-house design and fabrication of custom induction coils and tooling fixtures tailored to specific customer part geometries, enabling precise and repeatable heat treatment.
• Glass Bead Blasting Value-added surface finishing service using glass bead media to clean, finish, or prepare parts before or after heat treatment.
• Magnetic Particle Inspection Non-destructive testing service that detects surface and near-surface cracks and defects in ferromagnetic parts, used for quality verification after heat treatment.
• Metallurgical Support Technical consulting on metallurgy, including material selection, process specification, and failure analysis to support customer engineering teams.
