AEROSPACE CHASSIS ENGINEERING

Tight-Tolerance Electronics Enclosure Manufacturing

Flight electronics cannot tolerate chassis flexing, hole misalignment, or weld spatter. Fabtron integrates precision TRUMPF laser blanking with multi-axis CNC bending and automated PEM hardware insertion inside one facility.

Scratch-Free Forming

Urethane tooling film and precision ground TRUMPF segmented dies prevent micro-marring on pre-anodized or clad aluminum surfaces.

Integrated PEM Hardware

Automated Haeger insertion presses install blind threaded standoffs, studs, and miniature nuts with push-out force verification.

Card Guides & Extrusions

TRUMPF TruMatic 260 rotation punch stamps continuous PCB card guide tracks and thermal cooling louvers in a single automated pass.

Conductive Alodine Prep

MIL-DTL-5541 chemical conversion coating with masked conductive bonding areas for low electrical resistance grounding paths.
