Powder Coating Process & Requirements
Define the appearance and application
Share the intended indoor or outdoor use, color reference, gloss or texture and any applicable coating specification. A physical sample can help establish appearance expectations. Performance and durability requirements must be agreed for the product and selected coating system.
Preparation and functional surfaces
Mark threads, holes, electrical contact areas, sealing faces and assembly interfaces that require masking or dimensional protection. Preparation and coating thickness are reviewed together with the base material and part condition.
Coating inspection and production approval
Agree the inspection scope before production, including appearance and any specified thickness, adhesion or performance tests. Sampling and approval connect the finish requirements with the final component and the selected coating system.
Assembly, packaging and quotation
Powder coating is coordinated with machining, final inspection, assembly and packaging within the approved scope. Send drawings, alloy, quantities, color and finish requirements, masking details and packaging needs. Our team reviews the project before confirming the quotation.
