    Engineering Review & DFM for Aerospace Parts

    We start by reviewing your aerospace drawings, 3D models, and material requirements. Our engineers perform DFM and tolerance checks to ensure the design can be machined reliably while meeting structural and certification needs.

    • Validate critical fits, tolerances, and load paths for flight hardware
    • Suggest material and process adjustments to reduce risk and cost
  • Setup

    CNC Programming & First Article Planning

    Our team programs multi-axis CNC machines, defines tooling and fixtures, and prepares first-article inspection plans. Every setup is documented to support traceability and repeatable aerospace production.

    • CAM programming for 5-axis machining and complex features
    • FAI and inspection plan aligned with aerospace standards
  • Production

    Precision Machining with Tight Tolerances

    Aerospace parts are machined on calibrated multi-axis equipment with in-process inspection. Critical dimensions and surfaces are closely monitored to achieve micron-level tolerances where required.

    • Multi-axis milling and turning for structural and engine parts
    • In-process checks to control tolerances and surface quality
  • Finishing

    Surface Treatment & Quality Verification

    After machining, parts receive required aerospace surface treatments such as anodizing, passivation, or shot peening. Final inspections verify dimensions, surface finish, and documentation before release.

    • Aerospace-approved surface treatments and corrosion protection
    • CMM inspection and complete quality documentation
  • Delivery

    Traceable Packaging & On-time Shipment

    Finished aerospace components are serialized, packaged with protective materials, and shipped with full traceability documents. We coordinate delivery schedules to support your build plan.

    • Labeling and serialization for each aerospace component
    • Export-ready packaging and coordinated global shipping
