Dust-focused industrial protection

Precision NEMA 5 Enclosures for Dust-Heavy Industrial Environments

Cement plants, flour processing facilities, and coal handling sites need enclosures built to resist floating and settling dust. Enclosuremfg engineers custom NEMA 5 enclosures to help keep hazardous particulate matter out and protect sensitive electrical equipment from dust-related arcing risks.

Wider flanges and high-compression gaskets help create a consistent sealing interface—especially important where combustible or insulating dust can enter an enclosure and contribute to electrical ignition hazards.

Custom NEMA 5 enclosure engineered for dust-heavy industrial environments

Designed around the seal interface

Flange geometry, gasket compression, seams, and hardware all contribute to dust-ingress protection.

Built to address common ingress paths

Engineering protection where standard housings can fall short

Dust protection depends on more than the enclosure panel. Our design and fabrication approach focuses on the interface, formed geometry, sealed seams, and installed hardware.

01 / Seal compression

High-compression gasketing

High-durometer, closed-cell gaskets pair with oversized machined flange surfaces to promote uniform compression and resist fine, settling dust.

02 / Flange stability

Reinforced, extra-wide flanges

CNC press-brake formed flanges provide a wider, high-rigidity sealing surface to help reduce gasket deformation and support long-term seal integrity.

03 / Seam integrity

Fully sealed structural seams

Low-heat-input laser welding and high-penetration MIG/TIG processes help prevent dust-path migration through weld pores or pinholes.

04 / Hardware entry points

Secure, flush-fit installation

Automated clinching installs captive PEM fasteners and standoffs for a flush fit, helping close potential dust-entry gaps around hardware.

From CAD to coating

Integrated production for controlled performance

Enclosuremfg manages key manufacturing steps in-house to maintain control over enclosure geometry, fit, and finish.

Discuss your enclosure design
01

DFM engineering

A 5-person engineering team reviews 3D CAD models and optimizes bend lines and flange designs for your specified IP/NEMA rating requirements.

02

Fiber laser precision

12kW and 6kW fiber laser centers produce burr-free edges, supporting close gasket seating against the metal during assembly.

03

In-house large-format coating

An automated 2500 × 6000 mm powder coating line provides controlled finishing intended to help resist corrosion and abrasive-dust wear that can compromise a seal.
