First Injection-Molded Samples

Set up the sample plan for a mold trial, including drawing revision, critical dimensions, cosmetic checks and assembly approval.

Link the samples to a drawing revision

Mark the part and drawing revision on the sample plan. Agree how the trial batch and relevant cavity identification will be recorded, and which material, color and finish the samples are meant to represent.

Define dimension, fit and cosmetic checks

Identify where to measure, what reference surfaces to use and how to check the part in its assembly. Mark permitted gate or ejector locations and provide an agreed visual reference where appearance is important.

Record each decision before approval

Log open points by drawing requirement and sample ID. Mark what is accepted, what needs a correction and what must be checked again. Use the approved revision, results and agreed reference pieces to communicate the release decision.

Frequently asked questions

What should we check on a first molded sample?

Start with the part’s critical dimensions, fit and appearance requirements. Add tests that relate to its intended use and agree how those results will be recorded.

Can we use photos to approve the sample?

Photos are useful for visual discussion. For fit, measured dimensions or specified material performance, use agreed inspection evidence and physical parts where the checks require them.
