Design Guide

Wall Thickness / Radius

1.0–2.5 mm typical wall gauge

Min Feature Size

PEM nuts, studs, standoffs, blind rivets, captive screws

Surface Finish Options

Powder coating (RAL/Pantone), anodizing, chem-film (Alodine), silk-screening

Design advice

1/ Specify standard PEM hardware codesInclude industry-standard PEM fastener part numbers in CAD models to ensure exact thread sizes and standoff heights.

2/ Account for powder coat thickness on mating fitsAllow 0.3–0.5 mm clearance between slide-in covers, doors, and hinges to accommodate 80 µm powder coating thickness.

3/ Add stiffening ribs to large flat spansIncorporate formed stiffener ribs or hat-channels on large sheet panels to eliminate oil-canning without increasing sheet weight.

Enclosure Materials

Select from aluminum, cold-rolled steel, galvanized steel, or stainless steel depending on weight, shielding, and environmental exposure.

Aluminum 5052-H32

Lightweight, naturally corrosion-resistant, and thermally conductive. The preferred choice for desktop electronics, aerospace chassis, and portable instrument boxes.

What are Custom Sheet Metal Enclosures?

Custom sheet metal enclosures are fabricated protective housings built from cut and bent metal panels, engineered to house and shield electronics, power systems, and industrial machinery. They provide superior durability, thermal dissipation, and EMI protection compared to plastic housings.

✓ISO 9001:2015 certified enclosure manufacturing

✓NEMA 1, 4, 4X, 12 and IP54–IP66 rating compliance

✓Automated PEM fastener hardware insertion presses

✓Integrated EMI/RFI shielding design and gasket channels

✓In-house electrostatic powder coating line with RAL matching

✓100% mechanical fit-check and continuity grounding inspection

Pros and Cons of Sheet Metal Enclosures

Pros of Sheet Metal Enclosures

Zero Expensive Tooling

Fabricated via laser cutting and CNC press brakes without costly injection molding or die casting tooling, saving thousands of dollars upfront.

Superior EMI/RFI Shielding

All-metal construction provides natural electromagnetic interference shielding and chassis electrical grounding for sensitive circuits.

Infinite Customization & Rapid Iteration

Design revisions, cutout alterations, and dimension adjustments are implemented in software instantly without retooling delays.

Cons of Sheet Metal Enclosures

Higher Unit Cost at High Volumes

For quantities exceeding 50,000 units, die casting or plastic injection molding achieves lower piece-part costs.

Minimum Flange & Clearance Rules

Sheet metal requires press brake clearances and bend reliefs, limiting complex compound curves.

Assembly Labor

Multi-part enclosures require welding, fastener insertion, and gasket application compared to single-shot molded shells.
