Project Background
An Asia customer approached Domify with an early aluminum enclosure sample for a telecom equipment project. The unit housed an embedded industrial PC board, communication modules, internal cabling, and a compact power assembly. The customer needed an enclosure that could be assembled consistently, protect the electronics, manage heat, and transition from prototype quantities to stable production.
The project scope was not limited to manufacturing the existing design. Domify was asked to review the mechanical concept, identify production and assembly risks, improve the prototype, and prepare the OEM / ODM enclosure project for repeatable manufacturing.
Initial Sample Review
The engineering review began with the physical sample, available 2D drawings, PCB dimensions, connector positions, assembly sequence, and expected installation environment. Key dimensions were checked against the real components rather than relying only on the supplied enclosure files.
- Verified PCB mounting points, component heights, and internal clearances
- Compared connector locations with front and rear panel openings
- Reviewed cable bend space and access to internal fasteners
- Checked heat-producing components and their relationship to the aluminum housing
- Evaluated extrusion, CNC machining, sheet-metal, and surface-finish requirements
Mechanical Issues Found
The initial sample could be assembled, but several details created avoidable risk for production. These are common issues in an industrial PC enclosure project when the housing is designed before all electronic and manufacturing conditions are confirmed.
- Limited clearance around two I/O connectors made cable installation difficult
- Uneven mounting support allowed the PCB to flex during connector insertion
- One internal cable path crossed a fastening point and slowed final assembly
- The thermal contact area did not provide consistent pressure against the main heat source
- Some CNC features required unnecessary machining time without improving function
- Panel tolerances did not fully account for extrusion and surface-treatment variation
Engineering Improvements
Domify revised the mechanical details around function, assembly, and manufacturability. The goal was to solve the observed issues while keeping the enclosure architecture practical for tooling, machining, finishing, and future product variants.
- Adjusted panel cutouts and edge distances to improve connector access
- Added and repositioned mounting supports to reduce PCB movement
- Reorganized the internal cable route and provided clearer assembly space
- Improved the heat-transfer interface and controlled the thermal-pad compression area
- Simplified selected CNC operations to reduce machining time and dimensional risk
- Updated critical tolerances and added inspection points for repeatable assembly
A revised prototype was produced and assembled with the target components. Fit, fastening access, connector alignment, and thermal contact were reviewed again before the design was released for production preparation.

Final Production Preparation
After prototype approval, the enclosure data was organized for controlled production. The preparation stage connected the approved mechanical design with practical incoming inspection, machining, finishing, assembly, and packaging requirements.
- Released controlled 2D drawings and confirmed the approved 3D model
- Defined material, extrusion, machining, and surface-finish specifications
- Identified critical-to-fit dimensions and inspection methods
- Confirmed hardware, thermal materials, labels, and assembly requirements
- Prepared a pilot production check before volume scheduling
- Reviewed packaging protection for finished aluminum surfaces and machined interfaces
Why Mechanical Review Matters
A housing can look complete in CAD and still create problems during assembly or production. Early mechanical review helps reveal tolerance conflicts, connector-access limitations, thermal-interface variation, weak mounting support, and machining details that add cost without adding value.
For industrial equipment, these improvements support more than appearance. They help reduce rework, improve assembly consistency, protect electronic components, and create a clearer path from engineering sample to repeat production.
