Secondary Operations For Injection Molded Plastic Parts

Many plastic parts require more than molding. Painting, pad printing, laser marking, ultrasonic welding and assembly can all affect the final product, so they should be considered before tooling begins.

For printing or marking, the part needs enough flat area and correct surface texture. For welding or assembly, ribs, positioning features and strength around connection points should be reviewed. For painting, material compatibility and cosmetic standards should be confirmed early.

Planning secondary operations together with mold design helps reduce rework and keeps production flow more predictable from sample approval to shipment.

Tec-Shine can support molded parts with secondary processing and assembly planning, helping customers keep tooling, molding and finishing requirements aligned in one workflow.
