Injection Mold and Molded Parts Quality Control
Quality is controlled from the first customer discussion through mold design, machining, trials, inspection, packaging and delivery.
Evidence That Can Be Defined in the Quality Plan
Availability depends on the project and supplier. The required record list should be fixed before tooling or production begins.
DFM and revisionsApproved geometry, gate, parting, ejection and open-issue records.
Material evidenceGrade, color reference, supplier data or third-party report when required.
Trial and inspectionSample images, molding settings, key dimensions and correction status.
Delivery recordsApproved sample reference, packing evidence and shipment milestones.
Document boundary: a material or supplier certificate is not automatically a YonLion company certificate. Holder, issuer, scope and validity are identified before publication or buyer use.
Dimensional fit
Interlocking samples were measured and assembled so correction decisions could be tied to the buyer’s functional requirement.
Material decision
Two molded PP options were compared and the selected variant was carried into production.
Risk documentation
Slender features, draft, ejection and deformation risks were made visible before tool decisions.
