A paint defect that causes a round dent due to paint escaping. The root cause is not degreasing, but the oil content in the airline. This explains the key points of pretreatment and equipment management.
The moment the paint is applied, it escapes and creates a round dent. If changing the paint doesn't fix it, the cause lies with the materials and equipment. Eighty percent of the sources of paint beading are oil and silicone. ────────────── ■ Causes of Occurrence If oil or silicone remains on the painted surface, the surface tension changes in that area. The paint cannot spread and results in circular dents with a diameter of 1-3 millimeters. ■ The Truth The real culprit is not the degreasing process but the airline. Oil contained in the compressor's drain adheres to the parts just before painting. Silicone-based release agents and hand creams can also be sources of contamination. ■ Improvement Measures Implement a two-stage air filter and perform daily drain discharge. Manage the oil concentration of the degreasing solution and prohibit handling with bare hands. Please utilize the materials summarizing the standards for pretreatment and equipment management.

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.
