A coating that is too thick or too thin will result in defects. We will explain the management of film thickness from three aspects: dimensions, rust, and appearance.
Poor film thickness is a complaint factor that is often overlooked in visual inspections. A coating that is too thin reduces corrosion resistance, while a coating that is too thick can lead to assembly issues at screw parts, fitting parts, and around holes. In other words, film thickness is a management item that affects rust, appearance, and dimensions. Particularly in automotive parts, even a slight difference in thickness after painting can impact assembly and operation. Initially, we check for deviations from the standard values, measurement locations, production lots, and part shapes. The countermeasures involve determining measurement locations, frequency, standard values, and recording methods, as well as understanding where paint adheres easily for each part shape. If the measurement locations change every time within a lot, trends become difficult to see. By fixing the measurement points and comparing them with the production lot, it becomes easier to identify the causes. Managing film thickness also helps prevent dripping, color unevenness, and hole filling. Please utilize check materials for film thickness verification. It is more important to consistently measure the same location than to measure itself. Comparable records will serve as materials for cause investigation.

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.
