Rust immediately after preprocessing may actually be caused by condensation in the factory. We will explain measures for the rainy season to summer.
Right after the pretreatment, it is already rusting. The rust may be caused by condensation due to humidity. In an environment with 80 percent humidity, the recurrence of rust due to condensation doubles. ────────────── ■ Cause of Occurrence From the rainy season to summer, temperature differences within the factory can easily cause condensation on the surface of materials. The metal surface right after pretreatment is particularly prone to rust, and the condensed moisture directly turns into red rust. ■ The Truth Even if there is no problem with the pretreatment itself, rust can occur simply due to temperature differences in the storage location. Special caution is needed when moving items from an air-conditioned room to the outdoors due to the temperature difference. ■ Improvement Measures Shorten the time from pretreatment to painting, and manage the temperature and humidity of the storage location. If possible, use a dehumidifier to keep humidity below 80 percent. Please refer to the materials for managing pretreatment during the rainy season.

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.
