Challenges & Solutions For Connector Housings

  • 01

    Pin Cavity Alignment

    We utilize specialized multi-point fixturing to machine terminal paths within a strict +/- 0.02 mm tolerance, preventing pin deformation during automated mating.

  • 02

    Contact Terminal Retention

    Locking channel geometries and internal retention ledges are milled to exact depths, providing a secure mechanical hold that resists vibration-induced terminal back-out.

  • 03

    Moisture Ingress Protection

    By finishing sealing lips and cable entry bores to controlled Ra 0.8 - 1.6 um specs, we ensure uniform seal compression for IP67 or IP69K ratings.

  • 04

    Thermal Cycling Distortion

    We machine uniform wall profiles from high-stability materials to prevent structural warping across extreme automotive operational temperatures ranging from -40°C to +150°C.

  • 05

    Complex Multi-Row Architecture

    Leveraging simultaneous 5-axis toolpaths allows us to mill deep, high-density cavity patterns and thin partition walls without risking tool deflection.
