Why In-House Tooling Cuts Lead Time on New Product Introductions

Outsourced tooling is often the slowest link in an NPI schedule. Building jigs and fixtures in-house changes that math completely.

On a typical new product introduction, tooling lead time is the single biggest variable a program manager can't control — unless the tool room sits down the hall from the machining floor.

When our tool room builds a fixture, the machinist who'll run the part is often in the same conversation as the toolmaker designing the jig. Iteration that would take a two-week outsourced revision cycle happens in an afternoon.

What this looks like in practice

  • First-article fixtures built and revised in days, not weeks
  • Tooling changes made alongside process trials, not after them
  • No outside vendor queue between design freeze and first parts
  • Full ownership of tolerance stack-up from fixture to finished part

For customers running compressed NPI timelines, this is consistently where we take the most time out of a program — not in the machining itself.
