Hongming Sheng manufactures custom sheet metal enclosures, cases, boxes, chassis, cabinets, housings and shells according to customer drawings, CAD files and assembly requirements.

We support aluminum, stainless steel, carbon steel and galvanized sheet fabrication for industrial electronics, power equipment, automation systems and custom OEM products.

Custom Enclosures, Cases & Boxes

Different products may use different names, but the basic manufacturing requirements are often similar: accurate panels, openings, bends, mounting points and surface finishes.

• Electronic enclosures
• Metal cases
• Sheet metal boxes
• Equipment housings
• Protective shells
• Custom covers and panels

Chassis & Cabinet Fabrication

Chassis and cabinet projects may require internal brackets, mounting plates, doors, covers, hardware and assembly features.

• Server and rackmount chassis
• Electrical cabinets
• Control enclosures
• Industrial equipment cabinets
• Power equipment housings
• Battery and energy system enclosures

• PEM nuts and studs
• Doors, hinges and latches when required
• Removable covers

Engineering & DFM Review

Before production, key enclosure features can be reviewed according to the drawing, material and assembly requirements.

• Bend radius and bend relief
• Hole and cutout positions
• Panel overlap and cover fit
• Hardware locations
• Weld joint positions
• Internal assembly clearance
• Ventilation opening layout
• Critical dimensions and tolerances

Typical Applications

• Industrial electronics
• Automation equipment
• Electrical control systems
• Server and communication hardware
• Power electronics
• Battery and energy equipment
• Testing equipment
• Industrial machinery

Prototype & Repeat Production

We support prototype fabrication, sample assembly and repeat manufacturing for custom enclosures, chassis and cabinets.

Prototype builds can help verify panel fit, opening positions, hardware installation and assembly before repeat production.

Quality Inspection

• Material and thickness verification
• Overall dimensional inspection
• Hole and cutout position checks
• Bending geometry inspection
• Hardware installation verification
• Weld appearance checks when applicable
• Surface appearance inspection
• Assembly fit verification when required

What to Send for Quotation

• 2D drawing or 3D CAD model
• Material and sheet thickness
• Required quantity
• Critical dimensions and tolerances
• Surface finish and color
• Hardware requirements
• Welding requirements if applicable
• Assembly requirements

Confidential OEM Manufacturing
