Injection mold cost

Injection Mold Cost: What Drives the Tooling Line

The tooling line is one number. Program economics depend on how many molds you pay for and how volume amortizes that capital.

Two budgets

Tooling capital and piece price are different clocks

Buyers open with injection mold cost because it is the largest one time charge in a molding program. It is also the number most likely to mislead if it is read without annual volume and reorder plans.

Tooling buys an asset you own. Piece price buys machine time, resin, and handling on every order. A lower tooling figure can raise total program spend if it implies a second tool, a shorter tool life, or orders that cannot reuse the same cavity.

The tooling charge covers one hardened steel tool. Upload CAD for a figure tied to your geometry rather than a benchmark range.

Program view

One steel tool versus paying for steel twice

The comparison is program totals, not a single tooling line.

One hardened steel tool at NetProto

  • One qualification cycle on the tool that runs production.
  • Tool completed in 10 business days on qualified programs.
  • You own the mold once the tooling charge is paid.
  • Repeat orders run on the same tool without rebilling the tooling charge.

Tooling ladder elsewhere

  • Validation or interim tools that never see full production volume.
  • A second tooling invoice before production stabilizes.
  • Correlation work between parts from different cavities.
  • Budget spent on tools that do not carry into reorders.

Compare figures fairly

Send the same inputs to every mold maker

Missing inputs produce tooling figures that cannot be compared.

  • 3D CAD with draft, ribs, bosses, and undercuts visible.

  • Target resin family, even if the grade is not final.

  • Annual volume or first order size for amortization.

  • Cosmetic class and texture callouts on the drawing or CAD.

  • Critical dimensions separated from general tolerance bands.

Family and cavitation

Volume decisions that change both tooling and piece price

Cavity count and family mold layout change the tooling cost and the machine time per part. Those decisions belong in DFM before steel is ordered.

  • Family mold tradeoffs for related parts in one tool
  • Cavitation discussed as a volume tradeoff, not a menu SKU
  • DFM feedback before tooling release

FAQ

Injection mold cost questions

Can you publish a mold cost range?

No. Upload CAD for a tooling figure tied to your part.

Does a lower tooling figure always mean a smaller program total?

Not if it requires a second tool or short tool life. Compare total landed cost at your real volume, tooling included.

Who owns the mold?

You do, once the tooling charge is paid, and you can request the tool at any time.
