Rust prevention + friction coefficient management, improving torque management accuracy for screws.
High-performance surface treatment that combines lubricity and high corrosion resistance.
One property closely related to surface treatment is the coefficient of friction (slip resistance). Especially in the case of screw products, variations in the coefficient of friction during fastening can lead to insufficient tightening or over-torque, potentially resulting in various issues such as loosening of screws or indentation of the mating material. Our surface treatment not only improves rust resistance but also stabilizes within a specific range of coefficients of friction, enabling proper torque management. If you are experiencing issues with screw fastening or the coefficient of friction, please consult us. Additionally, if you are currently applying lubricants separately, our surface treatment can control the coefficient of friction on its own, making it possible to eliminate the use of lubricants. *Please note that the torque coefficient may vary depending on the conditions of the internal threads and the components being fastened.

Company information
At Kuroiwa Co., Ltd., we perform rust prevention surface treatment processes for metals, including Lafre, Disgo, Raspato, and Delta Protect treatments. Our processing does not involve any steps using acids or alkalis, resulting in no wastewater generation, making it an environmentally friendly closed system method. Additionally, due to the low-temperature baking treatment, there is minimal impact on the material properties, demonstrating our thorough consideration for the environment in our processing technology. We can accommodate surface treatment lots of any size, starting from small prototype quantities. Samples of treated products can be shipped free of charge. Furthermore, if requested, we can leverage our network with various manufacturers to handle parts procurement, perform surface treatment, and provide the finished products, or procure individual parts as needed. If you have any concerns regarding surface treatment, rust prevention, or parts procurement, we will utilize our experience and know-how to provide optimal proposals. Please feel free to consult with us.
