Contract Processing of Surface Treatment | How to Choose Treatment Methods and Classification Map
A classification map of surface treatments derived from the desired functions, including an explanation of the distinctions between coatings and plating.
Surface treatment encompasses a variety of methods, including resin coatings such as fluororesin, ceramic-based treatments, wet processes like plating, thermal spraying, and lining. It is crucial to clarify "what functions are needed" before determining "which treatment to use." Yoshida SKT Co., Ltd. selects surface treatments based on the specific functions required, such as non-stick properties, slip resistance, chemical resistance, heat and cold resistance, water and oil repellency, hydrophilicity, wear resistance, electrical properties, static prevention, dimensional stability, and coating surface roughness adjustment. In addition to coatings made from fluororesin, silicone, ceramics, urethane, and super engineering plastics (such as PI, PEEK, PBI, etc.), we also accommodate various processes, allowing for proposals that are not biased towards specific treatment methods. Since the functions required on-site are interrelated and complex, conducting technical discussions with a broad perspective leads to maximized effectiveness. We respond with a proven track record of supporting over 2,000 companies since 1963.
