A practical pre-tooling checklist for buyers covering design inputs, wall thickness, draft, parting, gates, venting, cooling, ejection and acceptance handover.
Align drawing revisions, material, quantities, appearance and acceptance requirements, then compare tooling, parts, trials, shipping and exclusions in one reply table.
After a T1 mold trial, link each issue to evidence, cause verification, corrective action, comparable retest results and a clear closure or open-item decision.
For a PC headlamp outer lens cover, mark controlled areas first, compare filling and meeting locations, and keep molded-in stress and validation limits explicit.
Review sink-mark risk around vacuum cleaner housing screw bosses by checking boss roots, hole bottoms, and rib intersections while separating geometry, material, process, and validation questions.
When a storage-box lid is hard to close or the rim gap is uneven, review body shape, lid shape, fit dimensions, material, wall variation, and analysis limits before tooling.
A practical review for molded-in grain on automotive door trim: separate texture boundaries, actual pull direction, ejector contact, and appearance constraints without assuming a fixed draft angle or resin.
Compare heat-set and molded-in threaded inserts for plastic power-tool housings by joint load, resin, volume, automation, tooling risk, and validation needs.
Review PP pill-box living-hinge cracking before tooling or tool changes by checking material version, thin-region geometry, filling risk, and first-article validation without inventing life or process limits.
