Storage of materials before painting is suffering from condensation in summer.
The materials left before painting are rusting due to condensation. This explains the storage troubles unique to summer.
Are the materials before painting rusting just by being left out? The cause may be condensation during storage. It is said that condensation begins to occur with a temperature difference of 5 degrees. ────────────── ■Cause of Occurrence Condensation occurs on the surface of materials due to the temperature difference between air-conditioned indoor spaces and the outdoors or warehouses. Metals, in particular, have good thermal conductivity and quickly react to temperature differences, resulting in water droplets. ■Truth Even if there are no issues in the painting process, the quality can deteriorate solely due to condensation during storage. Special caution is needed during periods of significant temperature changes from night to morning. ■Improvement Measures Minimize the temperature difference in the storage area and protect the materials by sealing or covering them. Allow time for the materials to acclimate to the temperature before proceeding with pre-treatment after delivery. Please refer to the materials for summer storage management.

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.
