What NPI Means Here

A Prototype That Predicts
Production. Nothing Less.

A prototype built on a bench by hand with manual crimp tools is not a production prototype — it is a geometry check. The failure modes that show up in production (inconsistent crimp height, routing interference, connector orientation errors) will not show up in a hand-built sample. We run prototypes on production equipment using the same process parameters because the NPI result must predict the production result. If it does not, the prototype is not useful.

Our NPI process feeds directly into production without a re-qualification step. The drawing, BOM, and traveler used in the NPI build are the production documents. The test fixture used on the prototype is the production fixture. You do not pay to qualify twice. If your program requires a specific production type (waterproof, high-voltage, or overmolded), see the respective pages — all NPI programs follow the same direct-to-production path.

Core Capabilities
1-Unit MOQ
No minimum order on prototype builds. One unit built to the same process, materials, and test standards as a production run of 10,000. The prototype is the proof, not a placeholder.
24-Hour RFQ Turnaround
Submit drawings, BOMs, or samples. Quote issued within 24 hours with material cost, lead time, and a DFM flag list if applicable. No consultant review — direct from engineering.
DFM Review Included
Every NPI build includes a design-for-manufacturability review at no charge. We flag unroutable geometries, non-standard connector orientations, and cost-reduction opportunities before cutting the first wire.
