Prototypes and Small Batches
One-off prototypes, limited runs and repeat small-batch orders, with the same program and setup reused each time you come back.
Why This Service Exists
GRACTS is built around the quantity most shops turn away: one piece to start, then the same part again when it sells.
The Problem
Production shops price small runs as if they were production, and a prototype shop cannot repeat the part consistently when the first batch runs out.
What You Get
You can start at one piece, prove the design, and reorder against the same program — without redesigning the part to suit a new supplier.
Built For These Projects
- Independent designers launching a first product
- Small brands restocking a machined component
- Engineers validating a design before committing to tooling
- Anyone whose annual volume never reaches a production MOQ

First Article
The first piece is machined and checked against the drawing.

Repeat Order
Reorders run from the same program, so later batches match the approved first article.
