What this service covers

Machined prototypes
Milled and turned first articles from your STEP file, in the material the production part will use.
Turned samples
Shafts, bushings and pins turned to the drawing, with the critical dimensions measured on the CMM.
Stamped prototypes
Die trials and short stamping runs from 0.5–25 mm sheet, deburred and finished before shipment.
Fastener samples
Non-standard screws and bolts cold-formed from your print, or matched against a sample you mail in.Why Lock
Why the first article decides the order
The sample is the argument
A drawing can hide a burr, a thread that will not start or a finish that pools in a corner. The first article shows all three before tooling is committed.
Same machines, same fixtures
Prototypes run on the equipment that will make production, so the sample is not a hand-finished exception to the process.
The report travels with the parts
Dimensions, thread gauges and hardness are recorded and shipped alongside the sample, so approval does not depend on a separate email.

FAQ
Common questions
How fast can I get a sample?
CNC turning samples typically take 5–7 days. Fasteners with an existing die take 7–10 days; a new die takes 15–20 days. Stamping follows the same rule — 5–7 days with a shared die, 15–20 days without one.
Do you charge for samples?
In-stock items are sampled free of charge. Custom parts carry a sampling fee, which covers the setup and the material rather than the part itself.
Can a prototype hold the production tolerance?
Yes, where the drawing calls for it — turned and milled features can hold ±0.005 mm on the same machines. The report states what was measured, so the claim is checkable.
Is my drawing confidential?
Your drawing is used only to quote and make your parts. An NDA can be signed before you upload, and files stay on our own server and are deleted after 180 days.
What is your minimum order?
One piece for machined parts. Stamping and cold-formed fasteners start from the tooling, which is quoted as its own line.
How do you ship, and who handles customs?
EXW, FOB, CIF, DDU or DDP — we can deliver to your warehouse and handle the clearance.
Have a drawing for this part?
Send it over — we will tell you what it costs and whether it is the right process.
