About Martinic Engineering
Martinic pairs advanced machining technology with experienced personnel and disciplined process oversight. The result is precision-machined aerospace components engineered for dimensional stability, material integrity, and long-term system performance.
History & Experience
Founded in 1978, Martinic Engineering has built a reputation for precision machining excellence in the aerospace industry. Acquired by PennAero Aerospace in 2013, Martinic operates as a Center of Excellence focused on highly engineered, tight-tolerance machined components for commercial and defense platforms.
From its 55,000 sq. ft. facility in Tolleson, Arizona, Martinic supports global aerospace primes and Tier 1 suppliers with complex machined parts and integrated assemblies designed for demanding operating environments.
Our Process Capabilities
Martinic combines advanced CNC programming expertise with disciplined manufacturing controls to produce components with tolerances as tight as ±.0002”. Engineering teams support new product development, build-to-print programs, and production transition strategies, ensuring manufacturability and dimensional control from prototype through sustained output.
Machining envelopes reach up to 25” × 25” × 20”, supporting complex geometries and large structural components. Parts are produced from solids, castings, and forgings using aerospace-approved materials.
Access to national and international standards, rigorous drawing control, and process documentation ensures conformance to specification across all product lines.
