Swannanoa, North Carolina · AS9100D & ISO 9001:2015
Precision machining, specialty tooling and subcontract manufacturing for aerospace, energy and defence customers — built on 30 years of family-run craftsmanship and certified quality systems with zero audit deficiencies.
We machine complex components in low-volume high-mix and high-volume low-mix environments. Materials range from steel and aluminium alloys through titanium and Inconel. Our customers include government-contracted high-tech programmes and commercial production alike.
Finished part envelopes run from the size of a screw up to Ø40″ turning and 96″ length on our large manual lathe — with Ø19.7″ × 11.8″ parts on our 5-axis machining centre.
Purpose-built tooling, fixtures and gauges for aerospace programmes.
Reliable subcontract machining for prime contractors and integrators.
Short-run and prototype production with fast turnaround.
Complete turn-key cells — machining, assembly and inspection.
