Custom Metal PCB Enclosures
Supro MFG builds custom metal housings for PCB assemblies. To quote a custom PCB enclosure, send your board outline and enclosure drawings. We review the board mounting pattern, connector cutouts and available space before quoting. Send the intended material, finish and quantity if you already know them.
Request a PCB Enclosure QuoteBoard Mounting, Connector Cutouts and Clearance
Start with the board outline, the mounting points and the locations of anything that must reach the outside of the enclosure.
Board mounting and standoffs
Show the PCB mounting holes, hole-to-hole distances and the required gap beneath the board. Indicate fixed standoff heights, thread sizes and any keep-out areas around the mounting points.
Connector cutouts and access
Provide the connector positions relative to the board mounting holes, along with panel thickness and plug clearance. Include any buttons, displays or removable panels that need tool or service access.
Component clearance and heat
Mark the tallest components, any heat-generating parts and the orientation of the enclosure in use. Identify your airflow, venting or heat-sink requirements so they can be reviewed alongside the housing geometry.
Metal Housing Examples
These housing photos show two metal part geometries to consider when specifying mounting features and enclosure openings.
Materials and Fabrication for PCB Housings
Folded sheet metal
For a base, cover and removable panels, compare laser cutting and sheet metal bending. Mark critical hole locations, bend clearances and access for attaching the board.
Machined or extruded housings
Where the enclosure needs machined mounting faces, threads or a repeatable cross-section, consider CNC machining or aluminum extrusion with secondary machining. Geometry and quantity guide the process choice.
Tell us if a finish, grounding contact or masked area is specified. Review surface treatment options when comparing materials and finishes.
Inspection and Project Requirements
Identify the dimensions that matter to fit and assembly, such as standoff height, thread size and the position of panel cutouts. Include the drawing revision and any inspection records you need with the quote.
Supro MFG holds ISO 9001 and IATF 16949 quality management certifications within their applicable scope. If your project specifies ingress protection, a NEMA enclosure type or EMI shielding, include the target and required verification so we can review it with the enclosure design.
From Sketch to Production
A board outline, a side view and the key connector locations are enough to start a discussion. Share your prototype and expected production quantities separately so we can review the manufacturing route for each stage.

PCB Enclosure FAQ
Can I request a quote without finished enclosure drawings?
Yes. Send a board outline or sketch showing the mounting holes, connector positions and available space. Flag any dimensions or materials that are still open.
Can you match an existing PCB mounting pattern?
Share a dimensioned board drawing or enclosure model. Include the connector faces, standoff requirements and any clearances needed to install or remove the board.
What if the enclosure needs an IP rating or EMI shielding?
Specify the target, operating environment and required verification when you request a quote. Include any mating panels, seals or grounding points that form part of the assembly.
