Relevant Capabilities

CNC milling and turning

Multi-axis milling and turning of bezels, plates, brackets, housings, and custom mechanical parts. Programmed from customer models and drawings to hold the tight tolerances required by display, panel, and enclosure assemblies.

In-house CNC and inspection equipment

Our machine shop runs HAAS vertical machining centers — including the VF-4SS, VF-4 with HRT210 4th-axis rotary, and VF-6SS with TRT310 trunnion for 5-axis work — backed by a HAAS CMM for in-house dimensional verification and traceable first-article reporting.

Display and instrument-panel fabrication

In-house machining of display bezels, instrument-panel plates, and faceplates that feed Polytronix display and panel lines. Single-source fabrication keeps mechanical hardware on the same schedule as the assemblies it supports.

Explore Instrument Panels

Enclosure and chassis machining

Fabrication and modification of metal and plastic housings, chassis, and cover plates, including cutouts, mounting features, and bracketry for box-build and electro-mechanical integration.

Explore Box Builds

Heat sink and thermal-component machining

Machined heat sinks, cold plates, and thermal plates supporting conduction-cooled assemblies. Mechanical features are produced to match the thermal-management hardware integrated at the assembly level.

Explore Ruggedization

Surface finishing and coatings

Anodizing, chromate conversion, plating, powder coating, and passivation applied to machined parts for corrosion resistance and appearance. Silk-screen and paint marking available for panels and bezels requiring legends or finish specifications.

First-article inspection and dimensional verification

Dimensional inspection and first-article verification of machined features against customer drawings before parts release to assembly. Measurement and traceability records support aerospace and defense quality requirements.

Assembly integration support

Machined hardware fed directly into Polytronix display, panel, box-build, and electro-mechanical assembly lines. In-house fabrication reduces handoffs, tightens schedule control, and keeps mechanical parts under single-source revision control.

Explore Electro-Mechanical

DFM and build-to-print support

Manufacturability review of machined parts and build-to-print fabrication from customer drawings. Engineering coordination addresses tolerance stack-up, material selection, and finish callouts before first article.
