Services
CNC Machining
Our multi-axis CNC machining capabilities produce complex prismatic components with minimal operations. Using quick-release tooling and automated processes, we achieve tight tolerances in temperature-controlled environments. This ensures consistent quality for high-accuracy aerospace and industrial applications requiring batch or volume production.
Aerospace Components
We manufacture critical aircraft components from nose to tail, including actuation systems, gearbox assemblies, and electronic enclosures. Our expertise covers civil and defence aviation requirements, with specialised capabilities in thin-wall machining and matched valve production for flight-critical systems.
NDT Services
NADCAP-approved non-destructive testing services include magnetic particle inspection, dye penetrant testing, and etch/passivate processes. Our certified technicians develop custom data cards and approval protocols to meet specific client requirements for mission-critical components.
Prototype Development
Our new product introduction (NPI) services transform concepts into proven prototypes. Leveraging 52 years of engineering experience, we provide concurrent engineering support from design validation through to production-ready manufacturing processes for complex legacy and next-generation components.
Thin-wall Machining
Specialised techniques developed over 12 years enable precision machining of delicate thin-wall components. This capability supports aerospace and oil & gas applications requiring high-strength, lightweight parts with exact dimensional accuracy and surface finish specifications.
