What JoVal Machine does

JoVal Machine Company, Inc. is a family-owned custom manufacturer founded in 1965 and headquartered in Yalesville, Connecticut, specializing in custom heat shield solutions and precision machined components. The company designs and manufactures heat shields, foil shields, and thermal blankets using stainless steel, nickel alloy steel, foil-gauge metals, encapsulated fiberglass, high-performance quartz fabric, and fiberglass insulation. Following its 2018 merger with Lab Threads & Gear Works (originally founded in 1952), JoVal expanded into custom gear cutting — spur and helical gears from 0.25 to 48 inches diameter, splines up to 9 inches — and thread milling for special form threads, spirals, trapezoidal screws, and lead screws up to 144 inches long. Production combines CNC machining (lathe and mill) with traditional processes including hobbing, shaping, broaching, and honing.

The company's primary customer base is aerospace, supplying heat shields to PRIMES such as Pratt & Whitney and Parts Manufacturer Approval (PMA) certified first-tier suppliers under FAA guidelines; its products feed engine platforms including the JT8D, V2500, PW4000, and PW1000GTF and ultimately reach Boeing, Airbus, McDonnell Douglas, and Mitsubishi regional jet programs. Secondary verticals include marine, power generation, medical testing, and antique auto restoration. JoVal holds ISO 9001 and AS9100C certifications, MIL-I-45208 inspection compliance, and DDTC Manufacturer Registration, and represents itself as a U.S.-made operation using domestically sourced materials.

The business model is a custom job shop operating on quote-based, project-driven pricing with no public pricing or subscription structure; revenue is generated from one-off custom parts and short production runs priced by complexity, material, and specification. Go-to-market is sales-led and consultative — direct phone, email, and contact-form engagement, supplemented by a website with downloadable product catalog, a Facebook page, and NTMA trade association membership. The company is privately held with no institutional investors, no funding rounds, and no public revenue disclosures; leadership consists of co-founder Gerald Chase (President) and his son Jeff Chase (Vice President).
