Build the die. Repeat the stroke.
Metal stamping uses presses and dedicated tooling to cut and form sheet or coil material into repeatable components through operations such as blanking, piercing, bending, drawing, and forming.
Material moves through controlled tooling while the press supplies the forming force.
A die can cut, form, or combine several operations in sequence.
Blanking
A defined piece of material is cut from larger sheet or coil stock and becomes the workpiece for later forming.
Piercing
Punch and die tooling create holes, slots, openings, and other internal cut features.
Bending
Controlled forming creates flanges, angles, tabs, and other changes in material direction.
Drawing
Sheet material is formed into deeper three-dimensional shapes such as cups, shells, and enclosed geometries.
Forming
Tool surfaces create ribs, offsets, embossments, channels, and other shaped features.
Trimming & Cutoff
Final trimming separates finished parts and removes material not needed in the completed component.
The die converts press motion into part geometry.
A press stroke performs one principal cutting or forming operation at a time.
Multiple cutting operations can occur during one press stroke at one station.
Coil material advances through multiple stations, with different operations performed as the strip progresses.
Individual blanks or partially formed parts move between stations for successive forming operations.
Dedicated inspection or secondary tooling may support quality checks, assembly, or downstream operations.
Stamping becomes more attractive when tooling cost can be spread across recurring production.
Dedicated dies can require substantial engineering and construction before production begins. Once validated, however, the process can support rapid and repeatable production cycles.
Design decisions influence die complexity, strip layout, forming, and tool life.
Material Thickness
Thickness affects cutting clearance, bend behavior, forming force, minimum features, and final stiffness.
Hole & Edge Spacing
Features placed too close together or near edges can create weak tooling conditions or material distortion.
Bend Geometry
Bend radius, direction, material properties, springback, and feature position influence forming results.
Tolerances
Tighter dimensional requirements may require additional die control, secondary processing, or inspection.
Material Utilization
Part orientation and strip layout influence scrap percentage and material cost during high-volume production.
Secondary Operations
Plating, heat treatment, deburring, machining, welding, assembly, and finishing can affect total process design.
