Prototype parts can prove a concept without proving that the production mold will run cleanly. Wall transitions, shut-off durability and ejection surfaces often change once the toolmaker begins the real DFM review.
We encourage customers to package prototype lessons in plain language: which dimensions matter most, where deformation already appeared and what assembly steps cannot change. This gives the mold engineer context that is rarely obvious from the CAD file alone.
A disciplined handoff creates better tooling decisions and fewer late-stage surprises. It also helps the buyer compare supplier feedback on the same engineering baseline.
