Metal Stamping Process & Production Workflow
The metal stamping process converts flat metal sheet or coil into formed, pierced, bent, drawn or trimmed parts through stamping dies and press equipment. For custom metal stamping projects, the process usually includes stamping design, CAE simulation, die engineering, die manufacturing, press tryout, sample validation and stable production.
Metal stamping is a manufacturing process that uses a press and stamping die to shape metal into parts. A complete stamping manufacturing process includes product review, material selection, die design, CAE simulation, machining, assembly, tryout, inspection and production control.
Metal stamping is a forming and cutting process where metal sheet is placed into a stamping press and shaped by a custom die. Depending on the part design, the stamping operation may include blanking, piercing, bending, flanging, drawing, trimming, restriking, tapping or multiple combined operations.
In industrial stamping production, the goal is not only to make the part shape. A reliable stamping process must also control burr, springback, material flow, tolerance, surface quality, die wear, production speed and long-term repeatability.
A professional stamping manufacturer should review the full workflow before cutting steel for the die. At Changdong, the metal stamping process is connected with tooling design, machining, press capability, inspection and production requirements.
Check part geometry, material, thickness, tolerance, forming difficulty and production volume.
Plan the stamping sequence, strip layout, forming direction, trimming strategy and die structure.
Evaluate thinning, wrinkling, cracking, springback and material flow before die manufacturing.
Use CNC machining, WEDM cutting, grinding, assembly and fitting to build the stamping die.
Test the die on a stamping press, adjust forming conditions and verify first samples.
Control stamping production stability, inspection frequency, die maintenance and output quality.
| Stage | Main Work | Engineering Focus |
|---|---|---|
| DFM and part review | Review product drawing, tolerance, material grade and production target | Formability, burr direction, hole distance, bend radius and cost risk |
| Process design | Decide progressive stamping, transfer die stamping or single-operation stamping | Production volume, part size, forming depth, coil use and press selection |
| CAE simulation | Simulate forming, thinning, cracking, wrinkling and springback | Material flow, drawbead design, blank holder force and springback compensation |
| Die design | Design die structure, inserts, punches, die plates, guide system and safety details | Die strength, maintenance access, alignment, clearance and production stability |
| Die manufacturing | CNC machining, WEDM cutting, turning, grinding, heat treatment and assembly | Machining accuracy, insert fit, cutting edge quality and assembly precision |
| Tryout and adjustment | Run the die on stamping press, inspect samples and adjust forming conditions | Cracking, wrinkles, springback, burr, feeding stability and part dimension |
| Mass production stamping | Stabilize output, inspection, die maintenance and production records | Cycle time, defect control, tool wear, production capability and repeatability |
Dongguan Changdong Tool & Die Co., Ltd. supports custom stamping manufacturing from CAE simulation and die design to die machining, assembly, press tryout and production validation. Our factory operates stamping presses up to 800T and manufactures stamping dies up to approximately 4 meters in length.
For automotive stamping, EV components, industrial metal parts and appliance-related stamping products, we focus on forming stability, die life, sample quality and repeatable production rather than only finishing the die build.
Different stamping products require different process routes. The best stamping process depends on part size, annual volume, material type, forming depth, tolerance and investment budget.
| Process Type | Best For | Typical Consideration |
|---|---|---|
| Progressive stamping process | High-volume small and medium parts produced from coil | High efficiency, stable feeding, good for continuous stamping process |
| Transfer die stamping process | Larger or deeper formed parts transferred station by station | Better flexibility for complex geometry and deep drawing features |
| Single-operation stamping | Prototype, low-volume or separate forming operations | Lower initial tooling cost, suitable for flexible production |
| Deep drawing stamping | Cup-shaped, enclosure, tray or automotive cover parts | Requires material flow control, blank holder force and springback control |
Material grade, thickness, tensile strength and elongation affect cracking, wrinkling and springback during stamping on metal.
Incorrect punch and die clearance can cause heavy burrs, poor edge quality, tool wear or inconsistent hole size.
For high-strength steel and automotive stamping parts, springback compensation should be considered during stamping design.
Press tonnage, bed size, stroke, feeding system and production speed must match the stamping die and part requirements.
| Problem | Possible Cause | Process Solution |
|---|---|---|
| Cracking | Poor material flow, tight radius, excessive stretching | Optimize forming radius, blank shape, lubrication and drawbead control |
| Wrinkling | Insufficient blank holder force or uncontrolled material flow | Adjust binder force, drawbead layout and forming sequence |
| Heavy burr | Improper die clearance or worn cutting edge | Correct punch-die clearance and maintain cutting edges |
| Springback | Material strength, forming angle and stress release | Use CAE prediction, compensation design and tryout adjustment |
| Unstable feeding | Strip layout, carrier strength or feeding pitch issue | Improve strip layout, pilot design and feeding control |
Many buyers search for stamping manufacturers or stamping service providers only after a part drawing is finished. In practice, early stamping design review can reduce tooling changes, lower material waste and avoid production problems such as cracking, burrs, springback and unstable dimensions.
A reliable metal stamping process connects product design, die engineering, machine stamping capability, inspection and production maintenance. This is especially important for automotive stamping, EV metal components and high-volume industrial stamping production.

Stamping is a manufacturing process that uses a press and die to cut or form metal sheet into required shapes. It is widely used for automotive, appliance, electronics, EV and industrial metal parts.
The main steps include part review, stamping design, CAE simulation, die design, die manufacturing, press tryout, sample inspection and mass production stamping.
Progressive stamping feeds coil through multiple stations in one die, making it suitable for high-volume continuous stamping. Transfer die stamping moves the part between stations and is often used for larger or deeper formed parts.
CAE simulation helps predict thinning, cracking, wrinkling, springback and material flow problems before the die is manufactured, reducing tryout time and tooling modification cost.
