Variations in film thickness are not due to differences in skill. This explanation will cover management methods that reconsider measurement points, jigs, and positions within the furnace.
The film thickness varies every time it is measured. Do you think it's due to the operator's skill? The cause lies in the measurement and hanging methods. ────────────── ■Cause of Occurrence Variability in film thickness arises from differences in static electricity due to the shape of the material and inconsistencies in measurement points. Even with the same part, there can be up to a 2-fold difference in film thickness between recessed and flat areas. ■Truth If measurements are taken without determining specific points, half of the variability is measurement error. Temperature differences due to the position within the furnace also affect film thickness; a 5-degree difference inside the chamber can change fluidity. ■Improvement Measures Fix three or more measurement points on the drawing and record separately for flat and recessed areas. Check the electrical connection of the jig daily and regularly measure the temperature distribution inside the furnace. Please utilize the documentation summarizing the criteria for setting film thickness measurement points.

Company information
We are not just a "subcontracted painting factory." Established in 1958, our company has a foundation of painting technology and also specializes in chemical treatment, stripping, and cleaning, functioning as the "external surface treatment department" in your organizational chart. Based on our philosophy of "preparation is eight-tenths of the work," we emphasize participation from the "upstream process" before the drawings are finalized. We conduct test painting on a wide range of metals and difficult materials, and we produce the entire process from assembly, packaging, to delivery, thereby reducing your management workload. Additionally, by being able to perform zinc phosphate treatment in-house, we achieve stable painting quality. Furthermore, our micro-heating stripping technology, which does not use chemicals, maintains the electrical state of the "jigs (hangers)" that influence painting quality. Our approach of "pre-treatment determines painting quality" ensures the stability of the paint film during mass production. Rather than simply "applying specified standards," we work backwards to achieve optimal painting specifications and prevent scratches during transportation, sparing no effort in thorough discussions from the outset. This diligent preparation is the shortest path to preventing rework and minimizing total costs. From the development stage, please utilize the expertise of our specialists as part of your production line.
