Progressive Die Stamping Services for Repeat OEM Production
HARVLAND makes repeat metal parts with progressive die stamping. A coil-fed strip carries the part through successive piercing, cutting, bending and forming stations, with the tooling and production route developed around your drawing.
Repeat parts with several cutting and forming operations
Brackets, clips, terminals and formed sheet-metal parts can suit progressive tooling when the design is stable and demand justifies a dedicated die. The part must remain supported as it passes through the stations.
- Holes, slots, outlines and bends can be combined in one planned route.
- Material grade, thickness and formed geometry determine which operations can be combined.
- For small batches or frequent design changes, compare tooling cost with single-station stamping or fabrication.
The strip advances; each station adds an operation
Between press strokes, the strip moves forward by one pitch. The next closing stroke works on parts at different stages simultaneously. Each individual part passes through the required stations over successive cycles before separation.
- The carrier supports the partly formed part until its planned cut-off point.
- Feed guides and pilots coordinate strip travel and final location.
- The sequence may include piercing, bending, forming or staged drawing, according to the part.
Progressive drawing along a carrier strip
From right to left, the drawn features become progressively narrower and taller while remaining connected to the carrier strip. This example shows the shape changing through successive forming stages.
Plan the stations around the finished part
Strip layout connects the finished geometry to the intermediate shapes. Hole positions, narrow connections and deep forms need enough support through later operations.
- Plan pitch, strip width and carrier geometry together with material use.
- Check springback, burr direction and tool access around bends and formed features.
- Keep mating dimensions and cosmetic surfaces in view when selecting the forming sequence.
Carry the approved sample requirements into production
Die trials establish the corrections and checks needed for the part. After sample approval, production follows the confirmed drawing and agreed inspection requirements.
- Check critical dimensions, burrs, forming marks and fit on trial parts.
- Define material, setup and in-process checks for recurring batches.
- Include deburring, finishing, packaging and tool maintenance where required by the project.

Send the part details for a progressive stamping review
Provide the current drawing and expected demand so the quotation can distinguish tooling, samples and recurring part production.
- 2D drawing or 3D model, material grade, thickness and finish.
- Annual demand, batch size and any expected design revisions.
- Critical dimensions, mating requirements, sample approval and delivery needs.

What is progressive die stamping?
Progressive die stamping carries a metal strip through successive cutting and forming stations. The strip advances between press strokes; during each working stroke, different stations act on parts at different stages. One part passes through those stages over several cycles before separation.
When is a progressive die more economical than single-station tooling?
It becomes attractive when part geometry is stable, repeat demand is high enough to spread the tooling investment and combining operations lowers total production cost. The break-even point depends on the specific part, material and program.
What information is needed for a progressive die quote?
Send controlled 2D and 3D files, material and thickness, annual and batch quantities, critical dimensions, burr direction, finish, sample expectations, inspection records and packaging needs.
Can a progressive die part be changed after tooling starts?
Some changes are possible, but they can require station, insert, strip-layout or inspection updates. Freeze functional requirements before tool release and use formal drawing revisions for any approved change.
How are progressive die samples approved?
Approval normally checks the agreed material, dimensions, burr and edge condition, formed geometry, appearance and assembly fit against the controlled drawing before pilot or repeat production is released.
