Hirschler Manufucturing

What Hirschler Manufucturing does

Hirschler Manufacturing Inc. is a privately held aerospace precision machining company founded in 1966 by Karl Hirschler and headquartered in Kirkland, Washington. The company specializes in producing complex, close-tolerance components from high-strength, difficult-to-machine materials including hardened steel, titanium, and nickel alloys, using modern CNC machining, gundrilling, broaching, EDM, grinding, honing, and CMM inspection in temperature-controlled environments. Its product portfolio spans chrome pins and shafts, internal and external splined parts, hydraulic swivel components and assemblies (production and spares), bulkhead and union fittings, aircraft hardpoints, titanium door components, and flight-critical assemblies such as 777 horizontal stabilizer components and 737 tail skid assemblies.

Hirschler sells exclusively through a direct B2B enterprise field-sales motion to a small set of major aerospace customers, including Boeing, Mitsubishi Heavy Industries, Kawasaki, Spirit AeroSystems, Magellan Aerospace, and Southeastern Technology Inc. Pricing is quote-based with no published tiers, and revenue is generated through custom prototype runs, continuous-flow high-production runs, and aftermarket spares. The company has held AS9100 aerospace quality management certification continuously since 2007, was named Boeing's Small Business Supplier of the Year, and claims the lowest rejection rates in the industry with documented multi-year streaks of zero-rejection production on tens of thousands of parts.

The firm operates as a single-site manufacturer under the 'Hirschler by Mecadaq' branding, with a lean organizational structure in which customers engage directly with senior management. It has no disclosed institutional funding, no acquisitions, no geographic expansion beyond the Pacific Northwest, and no AI/ML or software product surface. The business model is fundamentally that of a qualified, reputation-driven tier-2/tier-3 aerospace supplier whose revenue predictability is anchored by long-tenured OEM and tier-1 relationships but exposed to single-customer and program-level concentration risk.
