Low Volume Injection Molding: Cost Per Part and Break Even

Low volume does not have to mean a new tool every order. It means how tooling capital spreads across fewer parts per year.

Volume band

Low volume with one production tool

Low volume injection molding searches worry that steel tooling only works at massive scale. Tooling capital still amortizes across every part you buy over the program life.

NetProto has no minimum order quantity. A small first order does not force a different tooling approach or a throwaway cavity.

Orders

Repeat orders on one tool versus new tool per batch

Same hardened steel tool

  • First and reorder parts from identical cavities.
  • Tooling charge not billed again on reorders.
  • Tooling completed in 10 business days on qualified programs.

New tool per low batch

  • Sampling restarts each time.
  • Correlation risk between batches.
  • Capital spent repeatedly.

Plan a low volume SKU

  • Estimate year one and year three demand for amortization math offline.

  • Confirm reorder pricing uses the same tool.

  • Lock cosmetic criteria early to avoid steel changes.

Family option

Related parts in one tool

Family molds spread tooling across multiple SKUs when resin and color align.

  • Family mold guide
  • DFM before tooling release
