    Design Review for Enclosures & Connectors

    We review your enclosure and connector designs, focusing on critical dimensions, EMI features, and assembly clearances. Our engineers help refine details to simplify machining and assembly.

    • Check wall thickness, thread depths, and connector interfaces
    • Optimize features for EMC, heat, and assembly efficiency
  • Setup

    Precision CNC Programming & Fixturing

    We create CNC programs and fixtures to hold small, delicate parts securely. Setup focuses on repeatability and protecting critical cosmetic and functional surfaces.

    • Custom fixtures for small housings and connector parts
    • Toolpaths tuned for fine features and small radii
  • Production

    Clean Machining for Fine Features

    Parts are machined with tight control of burrs, flatness, and small features. In-process inspections ensure that critical dimensions and surface finishes meet electronics assembly requirements.

    • Burr control and precision hole positioning
    • Dimensional checks on connectors and mating interfaces
  • Finishing

    Anodizing, Plating & Clean Packaging

    We coordinate anodizing, nickel or gold plating, and other finishes needed for conductivity, insulation, or aesthetics. Parts are cleaned, inspected, and packaged to protect sensitive surfaces.

    • Functional finishes for EMI, corrosion, and wear
    • Clean packing to avoid contamination and scratches
  • Delivery

    Batch Traceability for Electronics OEMs

    Finished components are labeled by batch and part number, with supporting documentation for material and finish. We coordinate shipments to match your build schedule.

    • Batch IDs and part codes printed on labels
    • Protective cartons suitable for small precision parts
