A treatment that sterilizes E. coli and Staphylococcus aureus with ultra-fine unevenness! Since it is not a coating, it does not peel off, and there are no resistant bacteria because no chemicals are used.
The micro-dimple treatment creates uneven surfaces that are comparable in size to common bacteria. For example, bacteria can move freely on a stainless steel mirror surface, but on stainless steel treated with micro-dimples, the formed uneven surfaces hinder their ability to move and operate freely. Additionally, the uneven surfaces are thought to cause inhibition of flagellar movement, leading to self-damage in bacteria, which results in antibacterial effects.

basic information
In 2012, a technical university in Australia announced in Nature that the nanopillar structures present on the surfaces of cicadas and dragonflies have antibacterial properties. When observed from the side, they appear pillar-like, and when viewed from above, they look like fine irregularities. The antibacterial effect is achieved by creating these nanometer-scale irregularities through micro-dimple processing. In antibacterial efficacy evaluation tests (conducted by MISTEC, Kanagawa Prefectural Institute of Industrial Technology), it was found that out of 330,000 E. coli, almost none remained after 8 hours. The antibacterial activity value exhibited an astonishing effect of over 3.0.

Company information
As a leading company in WPC processing, we achieve further reduction in friction and improvement in wear resistance and seizure resistance by combining it with other surface treatments such as DLC/PVD coating. WPC processing continuously shot-peens the metal surface with micro-sized media, generating residual compressive stress on the surface while simultaneously forming countless micro-dimples, significantly improving the fatigue strength and sliding characteristics of sliding parts. Fujii WPC Co., Ltd. boasts a wide range of processing achievements in industrial fields, from automotive parts to molds, cutting tools, and other tools, as a leading company in WPC processing. With composite processing using DLC coating, high-quality coatings have become possible for aluminum materials, which were previously difficult to coat. Additionally, by applying WPC as a pre-treatment for PVD coatings on molds, cutting tools, and other tools, we can further enhance the excellent performance of PVD. The lifespan of automotive parts, metal components, molds, cutting tools, and other tools can be increased several times! Further durability and friction reduction can be expected through composite processing combined with nitriding, carburizing, high-frequency hardening, and coating. We offer short delivery times, and orders can be placed from just one piece, including composite processing.
