What Tube Processing Corporation does

Tube Processing Corporation is a private, family-owned precision metal components manufacturer and repair station founded in 1939 and headquartered in Indianapolis, Indiana. The company operates through two divisions — Aerofab, a Tier 1 supplier of manufactured components, and TPC Repair Station, an FAA/EASA/UK CAA-certified maintenance, repair, and overhaul (MRO) operation — serving the aviation engine, diesel engine, and industrial gas turbine engine industries. Its customer base centers on global aerospace and energy OEMs including Rolls-Royce, Siemens, GE Aviation, and Pratt & Whitney, with component manufacturing and repair activities embedded into engine programs such as CFM56-7, PW1500/PW1900, PW2000, V2500, and F117.

Aerofab provides full-spectrum, in-house metal processing including titanium hot forming (a stated industry-leadership capability), cold pressing up to 500 tons, vacuum and open-air heat treating, seven-laser multi-axis laser drilling and cutting with EDM, plasma/HVOF/TBC and abradable coatings, CNC milling and turning, NADCAP-certified welding (GTAW, orbital, resistance seam, stud), tube bending up to 3 inches, spin forming up to 38 inches, and NADCAP-accredited non-destructive testing (FPI, digital X-ray, pressure/flow testing). The Aerofab manufacturing stack holds six NADCAP accreditations, AS9100D / ISO9001 certification, and individual OEM quality system approvals (Rolls-Royce Corporate, SABRe, Civil & Defense; Siemens Certificate of Approval). TPC Repair Station delivers inspection, weld repair, coating repair, dent removal, flange and fitting replacement, and full overhaul of heat shields, ducts, manifolds, brackets, cases, coolers, and tube assemblies.

TPC generates revenue through three streams: direct component manufacturing sales to aerospace and energy OEMs (one-time/contract sales), recurring component repair and overhaul services through TPC Repair Station (professional services), and an à la carte Quick-turn Services line offering expedited access to individual manufacturing processes. Pricing is quote-based and not publicly disclosed. The go-to-market motion is B2B enterprise field sales targeting aerospace and energy buyers, supported by a vendor/supplier program, direct RFQ channels via division-specific email addresses, and credibility-driven marketing through publicly listed OEM and regulatory certifications. The company is privately held with no venture capital, private equity, or institutional investor ownership disclosed.
