Custom Date Tags

Manufactured to create a clear impression within the metal casting process, giving your users traceability they can read at inspection. Injection molded for high precision — and able to produce large, repeatable volumes at low cost.

Screw-In / Snap-In Fit

Mounting engineered into the tag — a hole pattern, boss, or snap feature designed around how your pattern is actually set.

Rapid Prototyping

Prove the impression, the fit, and the legibility on a real tag before any tooling is committed.

Made to Order

Every shape, size, font, and code — cut to your pattern and presorted so the bench mounts tags instead of sorting them.
