What Approved Sheet Metal does
Approved Sheet Metal is a U.S.-based, privately held precision sheet metal fabrication job shop founded in 2020 and headquartered in a 25,000+ sq. ft. facility in Hudson, New Hampshire. The company manufactures custom prototype and low-volume production parts (quantities from 1 to 5,000) using laser cutting, CNC punching, CNC forming and bending, welding, hardware insertion, finishing (powder coating, anodizing, plating), and assembly operations. It serves product developers, mechanical engineers, and OEM customers across medical devices, aerospace and defense, electronics and instrumentation, robotics, semiconductor equipment, and automotive, with named enterprise customers including Medtronic, Honeywell, Lockheed Martin, Parker, and Ametek.
The business runs on a custom ERP with real-time material inventory and job scheduling, supports CAD file intake in DXF, STEP, IGES, and SLDPRT formats, and operates a digital front door with an online RFQ system returning quotes within hours, same-day shipping for flat laser-cut parts ordered by 10 a.m. EST, and a content-marketing engine built around a SOLIDWORKS tutorial library, CAD tooling library, DFM eBook, and bend-gain charts. It holds ITAR registration (Cage Code 0PPQ6) and ISO 9001:2015 certification, the former enabling defense work and the latter supporting quality-sensitive customers.
Revenue is generated through project-based, quote-driven unit pricing with pay-as-you-go billing across prototype, low-volume production, and assembly service lines. Growth has been primarily inorganic: in 2023 the company acquired Technical Machine Components (relaunched as sister brand Approved Machining offering CNC precision machining) and Nashua Fabrication (sheet metal capacity expansion). Distribution is direct via inside sales and field account management serving all 50 U.S. states from a single facility.
