Prototyping is the busiest desk in the shop. Engineering teams send us drawings (sometimes finished STEPs, sometimes a sketch and a phone call, and ask how soon they can have a part in hand. The honest answer is usually days, occasionally hours.

We don't run a separate "prototype line." The same machinist who'd cut a 200-piece production run cuts your one-off, which means the program already accounts for what production would look like if the design proves out.

Material certs included with every prototype shipment. If a design will be a tooling problem at production volume, we'll tell you while it's still cheap to change.

Typical applications

  1. 01Single-piece validation parts for new product programs
  2. 02Mechanical mockups for industrial designers and product teams
  3. 03First-article parts ahead of a production run
  4. 04Replacement components reverse-engineered from broken originals
  5. 05Robotics and consumer hardware prototypes for early funding milestones

Common Questions

Questions buyers and engineers actually ask.

Simple one-off parts in 2–4 business days is typical. Complex multi-op parts in 5–8 days. Materials lead time is the most common delay; we keep standard alloys in stock to keep that short.
Sketches are fine. We've quoted parts from napkin drawings, exploded-view PDFs, and photos of a broken original. If a CAD file is needed for production-grade tolerances, we'll generate one. See our CAD/CAM service.
One piece. Most prototype jobs fall between 1 and 10 pieces.
