Startup Parts We Machine
We machine rapid prototypes and first-article parts for hardware startups moving from concept to production — enclosures, housings, functional prototypes, and design iteration parts. Common materials include 6061 aluminum, ABS, Delrin, polycarbonate, and 303 stainless.
Prototype Enclosures
Custom enclosures for early-stage hardware products machined from aluminum and engineering plastics. Iterate fast with production-quality surface finishes and tight tolerances from day one.
First Article Parts
First-article inspection parts with full dimensional reports to validate your design before committing to production tooling. We turn around first articles in 5–7 days.
MVP Housings
Minimum viable product housings machined to look and feel like injection-molded parts. Perfect for investor demos, user testing, and early customer shipments.
Functional Prototypes
Load-bearing, thermally conductive, or chemically resistant prototypes machined from the same materials as your production parts for real-world testing and validation.
Design Iteration Parts
Fast-turn revision parts so your engineering team can iterate weekly. We keep your CAD files on file and quote revisions in minutes, not days.
