The painted surface is sticky due to insufficient curing. The cause is a lack of control over the baking temperature and time.
Although it should have been painted, the surface is sticky. Poor curing is a defect that is not easily noticeable visually. ────────────── ■ Cause of Occurrence Poor curing is a phenomenon where the paint film does not cure sufficiently due to low baking temperature or short baking time. Stainless steel has low thermal conductivity, making it difficult for heat to penetrate to the interior. ■ The Truth Even if the set temperature in the oven is correct, it takes time for heat to reach the interior of the material. If the time is shortened, only the surface will be cured. ■ Improvement Measures Adjust the baking time according to the thickness of the material. Regularly measure the temperature in the oven and check for discrepancies with the management values. Utilize materials that provide guidelines for baking conditions.

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.
