Stamping Process Selection
Part Geometry Often Determines the Most Suitable Stamping Route
Custom stamping is not one single process. A flat bracket, a bent clip, a drawn cup, and a multi-feature electrical contact may require very different tooling and forming sequences.
The manufacturing route should follow the actual part geometry, material, thickness, quantity, and critical features shown on the drawing.

Flat Parts
Washers, plates, shims, flat contacts, and simple profiles may mainly require blanking or piercing.
Blanking / Piercing
Bent Parts
Brackets, clips, retainers, tabs, and formed supports may combine piercing with one or more bending stages.
Piercing + Bending
Drawn Parts
Cup-shaped, shell-like, or recessed components may require material to flow into a three-dimensional form.
Drawing / Redrawing
Multi-Feature Parts
Parts with holes, slots, tabs, bends, ribs, embossments, or several formed features may require a sequence of operations.
Progressive or Multi-Stage Forming
Large or Complex Parts
Some parts may require separate forming stages or transfer between operations depending on size and geometry.
Transfer / Separate Operations
Feature Position Can Change the Process
Hole Near a BendThe forming sequence should consider whether the hole is pierced before or after bending.
Deep FlangeA tall flange may require more forming control than a shallow bend.
EmbossmentRaised or recessed features may need a dedicated forming station.
Tab or HookSmall formed features should be reviewed for accessibility and material flow.
Drawn CornerMaterial behavior becomes more important where sheet metal is stretched into a deeper shape.
Quantity Also Influences the Tooling Route
A geometry that can be produced through several separate operations may also be suitable for progressive tooling when repeated production justifies the tooling approach.
The decision should consider part complexity, expected quantity, tooling requirements, material utilization, secondary operations, and future repeat demand.
Stamping Is Not Always the Only Option
● Laser cutting + bending may suit lower-volume sheet metal parts
● CNC machining may suit thicker or fully machined components
● Stamping becomes more attractive when repeated geometry and forming are required
● Some assemblies combine stamped parts with fabricated or machined components
What Helps Determine the Stamping Route?
MaterialSteel, stainless steel, aluminum, copper, brass, or another specified grade
ThicknessSheet thickness affects bending, drawing, piercing, and tooling design
GeometryHoles, bends, flanges, ribs, tabs, cups, and other formed features
Critical AreasDatums, burr direction, contact surfaces, assembly interfaces, or formed dimensions
QuantityPrototype, trial production, repeat order, or larger production demand
FinishPlating, passivation, powder coating, or other specified treatment
