Main fail
Internal edge ridge
Silk-screen after geometry
This page has no product photos. The cup job is NDA-bound; we will not drop an unrelated drinkware shot here. The record is still usable: STP/STEP concepts, a 1-cavity steel sample mold, matte cups at Shore A 50 and 60 (10 pcs each), later two black Shore A 70 feel samples, then silk-screen after the internal edge protrusion was removed.
Sequence that mattered: mold geometry first, decoration second. Mixing both into one approval forces reprint when the steel changes.
Why the ridge stopped print
The protrusion sat on an internal edge a drinker would feel. Small in section, obvious in the hand. It affected comfort, trim, look, and whether the later print sat on a stable surface. Logo artwork stayed in vectors, off the STEP, so the cup body could change without rewriting the art file.
Revised samples compared cleaned vs rounded edge treatments. That is a real trade-off: sharper looks crisp, rounder feels better. Production Shore was not frozen in the archive we can publish — 50 / 60 / 70 were comparison lots, not a catalog default.
What to send for a similar cup
- STEP of the cup without the printed logo, plus vector art separately
- Target Shore range and whether you need feel samples at more than one hardness
- Lip / rim notes, color, matte vs gloss, expected annual qty
- Decoration process (silk-screen, pad, in-mold) and when it is allowed to start
FAQ
Why no cup photo?
No publish-safe project still was cleared. Substituting a stock mug would imply a part we cannot show.
Did Shore A 70 win?
Not in the files we can cite. Two black 70s were a later feel check after 50 and 60 sampling.
Steel sample for a cup — is that always the path?
This job used a 1-cavity steel sample mold because the lip geometry had to be real. Other drinkware may start differently; send the STEP and we say which path.
