Management of non-painted areas to prevent masking defects.
Paint adhesion to the screw parts or contact points can lead to assembly defects or electrical conduction issues, even if it occurs in just one location.
Masking defects are failures where paint adheres to areas that should not be painted. Areas such as screw parts, contact points, fitting parts, grounding parts, and drainage holes can cause the customer's assembly process to stop even with just one instance of adhesion. Even if it appears as a small overflow visually, it directly leads to functional defects such as screws not fitting, lack of electrical conductivity, or parts not fitting together. Initially, we check the drawing instructions for unpainted areas, the position of masking materials, any lifting, and the number of times they can be reused. The countermeasures involve standardizing four points: masking range, materials used, application procedures, and inspection methods. Additionally, separating pre-work checks from post-painting checks makes it easier to identify forgotten areas, lifting, and misalignment. When reusing masking materials, it is also necessary to check for deterioration and loss of adhesive strength. Please utilize check materials for managing unpainted areas. Since issues with unpainted areas often arise in later processes, having a system to verify them as functional parts before shipment is effective.
