FPM Heat Treating

What FPM Heat Treating does

FPM Heat Treating is a privately held commercial heat treating company founded in 1979 and headquartered in Elk Grove Village, Illinois. It operates two integrated manufacturing facilities in Illinois — the original Elk Grove Village site and a second plant in Cherry Valley — and serves more than 3,000 customers across the Greater Midwest. Its end markets span OEM manufacturers, military and aerospace, automotive, construction and agricultural equipment, appliances and consumer products, machinery components, and tooling. The company positions itself as "the only Commercial Heat Treat Licensee in North America for Nitrotec™ processing," a patented nitriding, oxidizing, and protection surface treatment licensed exclusively to FPM.

FPM's service portfolio covers a complete spectrum of thermal processing: Batch I/Q furnaces (carbon-controlled, up to 4,000 lb loads), Continuous Belt furnaces (over 4,000 lbs/hour throughput), Vacuum furnaces (10 bar rapid quenching, up to 5,000 lb loads and 48"×48"×72" work envelope), Salt Bath lines for austempering and marquenching, Nitrotec™ furnaces, Thermal Hydraulic Flattening (300°F–1,300°F), and ancillary processes including induction hardening, straightening, blast cleaning, and cryogenic treatment. Every location houses an in-house metallurgical laboratory staffed by licensed, degreed metallurgists and material scientists providing Knoop/Vickers/Rockwell hardness testing, optical microscopy, alloy identification (OES, spark testing, carbon analysis), and liquid dye penetrant non-destructive testing. The technology base is industrial process equipment with computer-controlled automation and metallurgical verification, gated by ISO 9001:2015 (BSI), NADCAP heat treating and AC7004 AQS certifications, and ANAB accreditation that enable access to military, aerospace, and OEM-grade work.

Commercially, FPM operates a job-shop / toll-processing model. Customers submit parts and specifications; FPM processes them through thermal treatment on a per-job or per-pound basis. The go-to-market is sales-led, with direct phone (847-228-2525) and email ([email protected]) contact supplemented by an industry-segmented website quote form covering ten verticals (Tool and Die, Machinery, Aerospace and Defense, Automotive, Agriculture, Construction, Heavy Truck, Medical, Consumer, Industrial). All pricing is custom-quoted; no public price list exists. Revenue mix is diversified across these verticals and the 3,000+ customer base, though no revenue figures, top-customer concentration, contract terms, ownership structure beyond "independently held," or third-party financial validation are publicly disclosed.
