The cause of paint peeling is poor adhesion. By simultaneously optimizing degreasing and chemical treatment, the occurrence rate can be reduced by 99 percent.
Paint peeling is a defect where the paint film lifts from the material and gradually comes off during use. This not only reduces the appearance quality but also affects the entire manufacturing site, as the peeled paint film can adhere to other products. Importance of the degreasing process: Insufficient degreasing is the main cause of paint peeling. By maintaining the degreasing solution temperature above 50 degrees, the oil removal efficiency improves by 60 percent. Regularly replacing the degreasing solution (every 7 days) can keep the degreasing efficiency consistently above 95 percent. Optimization of chemical treatment: By managing the chemical treatment film thickness within plus or minus 1 micron and maintaining a thickness of 8-10 microns, adhesion is maximized. Keeping the crystal diameter between 5-15 microns enhances long-term adhesion. Impact of humidity management: If the humidity just before painting is above 70 percent, moisture adheres to the material surface, leading to poor adhesion. It is essential to ensure a drying time of one hour before painting and to manage humidity below 50 percent. Our company optimizes degreasing, chemical treatment, and drying, achieving a 10-year warranty against paint peeling. We also guarantee quality even for small lot short delivery requests.

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.
