Standardization and documentation to reduce defects at painting sites with labor shortages.
It is important to manage preprocessing, film thickness, and baking conditions through records, rather than relying solely on the intuition of skilled practitioners.
■Cause of Occurrence: In metal coating, the shortage of manpower and the difficulty of skill transfer lead to quality defects. Experienced workers can notice residual oil, excessive film thickness, insufficient drying, and areas prone to dripping, but inexperienced workers may overlook these issues. Coating peeling, pinholes, poor curing, and blisters occur due to the accumulation of small variations in judgment. ■Truth: The danger of manpower shortages lies not only in the number of workers but also in the fact that judgment criteria can vary from person to person. If film thickness is judged by feel, curing conditions are not recorded, and drying conditions are assessed only visually, the same defects cannot be prevented. Clear standards that anyone can understand are necessary. ■Improvement Measures: Record degreasing conditions, drying times, film thickness measurements, curing temperatures, and inspection results, and standardize the three aspects of work procedures, inspection criteria, and defect confirmation procedures. Please utilize materials that allow you to verify pretreatment, film thickness, and curing conditions.
