High-Volume Precision Component Manufacturing

Metal stamping converts coil or sheet stock into components using custom die tooling. It can support repeatable production and unit cost efficiency for medium-to-high volume runs when the design and process are suited to stamping.

A Design for Manufacturability (DFM) review can assess strip layout, material use, die maintenance and secondary operations before tooling is fabricated. Tooling ownership and maintenance responsibilities are defined with the project scope.

  • Review strip layout and die concept before tool fabrication
  • Agree tooling ownership and maintenance responsibilities up front
  • Consider tapping, hardware insertion, deburring and finishing as secondary operations

Stamping Process Capabilities

Tooling methods are selected against part geometry, complexity, material and planned volume.

  1. 01

    Progressive Die Stamping

    Coil-fed strip advances through successive stations for piercing and forming. It may suit repeat components such as brackets, clips, hinge leaves and electrical terminals.

  2. 02

    Transfer Die Stamping

    Individual blanks move between die stations. This method can suit larger components and deeper forms that need separate station handling.

  3. 03

    Compound Die Stamping

    Blanking and piercing are combined in one press stroke. It may suit flat profiles such as washers, plates and shims.

  4. 04

    Deep Drawing

    A sheet blank is formed into cups, enclosures or shells through one or more draw stages. Material flow and part geometry are assessed during tooling review.

  5. 05

    Secondary Operations and Assembly

    Tapping, hardware insertion, deburring, finishing and other follow-on work can be reviewed as part of the proposed manufacturing route. Availability and scope are confirmed for each project.

Design for Manufacturability (DFM) Guidelines

These are starting points for review. Material, geometry, tooling and functional requirements can change the recommendation.

  • Hole proximity to edges

    A hole-to-edge distance around twice the material thickness is a common starting point. Confirm the minimum against material, hole size and edge condition during die review.

  • Recommended bend radii

    An inside bend radius at or above material thickness is a useful initial guideline. Review tighter radii against grade, temper, grain direction and forming method.

  • Manage material springback

    Review springback for the selected grade and geometry. Ribs or coined bend lines may be considered where they suit the part and function.

  • Minimize narrow features

    Review narrow webs and punches with the tooling designer, since feature width, material and clearance affect tool strength and maintenance.

  • Standardize material gauges

    Consider standard commercial sheet and coil gauges where they meet design requirements and are available for the project.

From Drawing to Stamped Parts

Review points and deliverables are agreed for the project before each stage proceeds.

  1. 01

    Quote and DFM review

    Review the drawing, material, quantities and intended use to define the initial process and quotation scope.

  2. 02

    Tooling concept

    Review strip layout and die concept, including ownership and maintenance terms, before tool fabrication.

  3. 03

    Tooling build and samples

    Plan tryout and sample review around the approved design and agreed inspection requirements.

  4. 04

    Production release

    Review first article results and any requested PPAP documents before production release, as defined in the project scope.

Stamping Questions

Which stamping method is right for my part?

The choice depends on part geometry, material, volume and production requirements. A drawing and quantity review helps identify suitable options for quotation.

Can you provide FAI or PPAP documents?

FAI and PPAP documentation can be requested for review. The applicable level, records and timing are confirmed in the project scope.

How are tolerances and material thickness determined?

They are reviewed against the drawing, material grade, tooling approach and available press capacity. Requirements are agreed before the project proceeds.

How are tooling and production lead times set?

The quotation defines the proposed schedule after drawing, tooling, quantity and inspection requirements have been reviewed.

Have a stamped part to source?

Share your drawing, material and expected volume for a review of the project requirements and quotation scope.
