Metal Fabrication

Start flat. Cut, bend, join, finish.

Sheet metal fabrication converts flat metal stock into brackets, panels, enclosures, frames, housings, cabinets, covers, chassis, and assemblies through cutting, forming, joining, and finishing.

Fabrication Operations

A fabricated part may pass through several different processes.

01 / CUTTING

Laser Cutting

Programmed cutting creates profiles, holes, slots, and internal features from flat sheet or plate.

02 / PUNCHING

Turret Punching

Punch tooling can create holes, slots, formed features, and repeated geometry efficiently in sheet stock.

03 / FORMING

Press Brake Bending

Punches and dies bend flat sheet along controlled lines to create flanges, channels, boxes, and structural forms.

04 / JOINING

Welding

Separate fabricated components can be permanently joined into frames, housings, structures, and assemblies.

05 / HARDWARE

Hardware Installation

Threaded inserts, studs, nuts, standoffs, rivets, and other hardware can be installed after forming.

06 / FINISH

Surface Finishing

Powder coating, painting, plating, polishing, brushing, and other finishes can protect or improve appearance.

Fabrication DFM

The flat pattern and the finished geometry have to agree.

01
Bend radius

Material thickness, tooling, alloy, and bend method influence the achievable inside bend radius.

02
Bend allowance

The developed flat length must account for how material stretches and compresses through the bend.

03
Hole placement

Features too close to bend lines or edges may distort during forming.

04
Tool access

Closely spaced flanges, deep boxes, and return bends can interfere with press brake tooling.

05
Weld distortion

Heat input, joint design, weld sequence, fixturing, and material thickness influence assembly distortion.

Industrial fabrication equipment
Fabrication Tolerances

A tolerance can cross several fabrication operations.

Dimensions on a finished assembly may depend on cutting accuracy, bend position, bend angle, springback, hardware installation, weld distortion, and final inspection.

Separate critical interface dimensions from general dimensions
Account for bend and weld variation in assembly stacks
Identify datums that can be measured after fabrication
Consider whether machining is needed after welding
Define cosmetic surfaces and allowable finish conditions

Need repeated sheet-metal parts at higher production volumes?

Metal stamping uses dedicated dies and press equipment to produce formed sheet-metal components efficiently at recurring quantities.
