Small factory. Serious precision.
Large platforms are built for scale. We’re built for the jobs that don’t fit their model: 10 parts with a tight bore, 200 brackets that must match a prototype exactly, a re-order identical to the last one.
Small batches are our main business
Prototypes and runs of 1 to a few thousand pieces are what we schedule around. Your order won’t wait behind a 50,000-piece job.
Same precision at any quantity
A batch of 5 gets the same setup checks, first-article inspection and final inspection as a batch of 5,000.
Talk to the engineer
Questions about a tolerance, a thread or a material go straight to the engineer who programs your part. Fewer emails, fewer mistakes.
Flexible when plans change
Revised drawing, split delivery, an urgent extra 20 pieces — a focused shop can re-plan in hours, not weeks.
Have a small batch that big suppliers keep pushing back?
