Technology Never Stands Still, and Neither Do We
Validated Mini-ITX platforms engineered for reliable deployment in industrial, edge, and embedded system environments.
Mechanical Manufacturing for Embedded Systems
Mechanical & Enclosure Manufacturing
Manufacture sheet-metal chassis, CNC-machined housings, aluminum extrusions, printed prototypes, brackets, panels, and custom heatsinks around the released Mini-ITX system geometry. Process selection follows the part shape, material, quantity, finish, thermal path, and inspection requirements.
Released Hardware Geometry
Manufacture the Enclosure Around the Actual System
Mechanical manufacturing starts when the critical hardware interfaces are defined well enough to quote and build. A Mini-ITX motherboard uses a 170 × 170 mm board outline, but the enclosure must also accommodate connector bodies, mating plugs, cable bends, memory, storage, heatsinks, fans, antennas, expansion devices, and service access.
If connector location, board keep-outs, or heatsink interfaces still need to change, resolve them in custom Mini-ITX board design before releasing metal. For low-profile systems, Thin Mini-ITX platforms can also change the available enclosure height and cooling approach.
Manufacturing Route
Choose Sheet Metal, CNC, Extrusion, or AM by Geometry
| Process | Best Fit | Decision Driver |
|---|---|---|
| Sheet Metal | Chassis, covers, trays, brackets, panels, and folded housings. | Consistent wall thickness, bends, cutouts, inserts, and efficient material use. |
| CNC Machining | Precision housings, pockets, bosses, sealing faces, threaded interfaces, and thermal plates. | Three-dimensional geometry, localized tolerance, machined datums, and low-to-moderate volume. |
| Extrusion + CNC | Long aluminum housings with repeating cross-sections, rails, screw channels, or cooling fins. | Reusable profile geometry plus secondary machining for ports, end faces, and local interfaces. |
| 3D Printing | Fit checks, ducts, brackets, fixtures, and low-volume geometry difficult to machine. | Fast iteration, with process-specific limits on strength, heat, finish, and dimensional behavior. |
Before Quotation
Send the Geometry and Requirements That Control Acceptance
A STEP model communicates nominal geometry. A production drawing carries the requirements the model may not show: datums, tolerances, threads, material, surface texture, finish, masking, cosmetic zones, inspection requirements, and revision identity.
- 3D CAD
- STEP/STP or equivalent geometry for pockets, bends, bosses, cutouts, interfaces, and assembly review.
- 2D Drawing
- Critical dimensions, GD&T, threads, material, finish, surface requirements, masking, and drawing revision.
- Hardware Interfaces
- Exact board revision, connector zones, thermal contacts, fan locations, cable exits, antennas, and replaceable parts.
- Commercial Inputs
- Prototype and production quantity, cosmetic expectations, target process, inspection records, and packaging requirements.
Sheet Metal Enclosures
Control Bends, Inserts, Openings, and Finish Together
Sheet-metal fabrication suits Mini-ITX chassis, internal trays, removable covers, rear panels, PSU brackets, and mounting plates. Laser cutting or punching creates the flat geometry; forming, inserted hardware, joining, finishing, and inspection create the released part.
Bend Geometry
Inside radius, flange length, bend direction, reliefs, hole-to-bend clearance, and tool access depend on material, thickness, and tooling.
Inserted Hardware
Captive nuts, studs, standoffs, and threaded inserts need controlled hole geometry, edge distance, insertion direction, and installation access.
Grounding & Finish
Define powder coat, plating, masking, bare-metal bonding points, threaded features, and cosmetic faces where electrical or appearance requirements differ.
CNC Enclosure Machining
Machine the Interfaces That Need Local Geometric Control
CNC machining is appropriate when one part combines cavities, connector openings, integral bosses, threaded holes, gasket lands, mounting datums, or heatsink contact surfaces. Critical features should carry the tolerance that protects function instead of applying one tight tolerance to every face.
Extruded Aluminum Housings
Use Extrusion When the Cross-Section Repeats
Aluminum extrusion can integrate enclosure walls, card guides, screw channels, mounting rails, and cooling fins into one continuous profile. CNC machining then creates connector openings, end faces, threaded holes, sealing features, and other local geometry.
ASTM B221-21 and B221M-21 cover aluminum-alloy extruded bars, rods, profiles, and tubes. Alloy, temper, profile tolerances, finishing, and secondary machining remain drawing and supplier-capability decisions.
Additive Prototypes
Use 3D Printing to Resolve Fit Before Cutting Metal
Printed parts can answer enclosure questions quickly: connector access, cable paths, fan ducts, bracket position, display openings, assembly sequence, and technician hand clearance. They should not be treated as proof of the strength, thermal conductivity, EMI behavior, sealing, or finish of the final metal enclosure.
Custom Heatsink Manufacturing
Define the Contact Path Before Choosing the Metal Shape
A heatsink or chassis-coupled spreader starts from the heat-source location, contact area, mounting method, thermal-interface material, available height, fin direction, airflow, and enclosure connection. For fanless Mini-ITX design, the enclosure can become part of the heat path rather than a passive shell.
Typical Aluminum Association reference data list thermal conductivity near room temperature at about 167 W/m·K for 6061-T6 and 209 W/m·K for 6063-T5. These are material-property references, not heatsink performance ratings; geometry, interface resistance, airflow, orientation, and ambient conditions determine the final thermal resistance.
Projects targeting wider ambient conditions should also review the complete wide-temperature platform rather than treating the heatsink as an isolated component.

Mechanical Release
Release Identified Parts Into System Assembly
Mechanical manufacturing ends with parts tied to the released drawing, material, finish, and required inspection record. The accepted parts can then enter box build and system integration with the approved motherboard, PSU, storage, cooling hardware, harnesses, and peripherals.
FAQ
Mechanical & Enclosure Manufacturing Questions
Sheet metal or CNC enclosure?
Choose sheet metal for folded housings and panels. Use CNC when the part needs cavities, bosses, sealing faces, precision bores, or localized geometric control.
What files are needed?
Send a STEP model plus a drawing with material, tolerances, threads, finish, masking, quantity, critical interfaces, and required inspection or documentation.
Which aluminum suits enclosures?
It depends on the process. Sheet, CNC, and extrusion use different alloy and temper choices based on forming, strength, machining, finish, corrosion, and heat transfer.
Can you manufacture custom heatsinks?
Yes, from an approved design. Define contact geometry, mounting, material, fin envelope, airflow or orientation, finish, and dimensional inspection requirements.
Can 3D printing make enclosures?
Yes, for prototypes and selected production uses. Material, orientation, heat, strength, finish, EMI, sealing, and dimensional requirements determine suitability.
