We faced the issue that, although some parts were changed to resin gears for the purpose of quantification, there was a strength difference compared to the metal gears, leading to wear on the resin gears. Therefore, we applied a dry lubrication coating to the metal gears. As a result, the lifespan of the resin gears was extended, significantly increasing the lifespan of the unit, and reducing dust generation believed to be caused by the resin gears, leading to effects beyond our expectations. [Case Summary (Excerpt)] ■Challenge - Some parts were changed to resin gears for quantification, but there was a strength difference compared to the metal gears, causing wear on the resin gears. ■Solution - Apply a dry lubrication coating to the metal gears. - This allows for smoother sliding and reduces wear on the resin gears. *For more details, please refer to the PDF document or feel free to contact us.

"When machining sintered parts, burrs occur on the finished surface, and while we want to improve machinability, changing processing conditions or cutting oils is cumbersome, so we were wondering if there is a better method." Sintered parts are intermittently processed materials with fine pores, which can easily generate frictional heat on the cutting surface, leading to plastic deformation and causing burrs. However, by using resin impregnation treatment to fill the pores, we can suppress the generation of frictional heat and improve machinability. Since adopting the resin impregnation treatment, burrs on the finished surface have almost ceased to occur, and processing defects have been reduced. 【Case Summary (Excerpt)】 ■Challenges - Burrs occur on the finished surface when machining sintered parts, and while we want to improve machinability, changing processing conditions or cutting oils is cumbersome. ■Solution - By filling the pores with resin impregnation treatment, we can suppress the generation of frictional heat and improve machinability. *For more details, please refer to the PDF document or feel free to contact us.

"5100" is a sealant suitable for sealing gaps inside electric wires, wire harnesses, and similar applications. It maintains flexibility even after curing, making it suitable for sealing gaps in molded parts of connectors and sensors. Have you ever experienced oil or humid air leaking through gaps inside a wire harness? Or have you encountered situations where the insulation was damaged during use, allowing water to enter? In such scenarios, our impregnating liquid "5100" demonstrates high reliability. Additionally, "5100" retains high flexibility even after curing. Due to the differences in thermal expansion coefficients between resin and metal molded products, gaps can significantly shift when subjected to thermal shock. Even in such cases, "5100" moves with the shifting gaps, helping to minimize their occurrence. 【Basic Properties】 ■Material Acrylic resin ■Heat Resistance -40℃ to 150℃ 【Target Materials】 ■Fluoropolymer wires ■Cross-linked polyethylene wires ■Super engineering plastics such as PPS and PEEK ■Engineering plastics such as PA6, PA66, POM, and PBT

The molybdenum disulfide coating material we handle can be applied to various metals. The primary performance of the coating is derived from its low friction coefficient, which provides lubrication, but it also enhances wear resistance and corrosion resistance, among other benefits. Additionally, since molybdenum disulfide is a mineral, it has properties that make it strong against loads and chemicals. Therefore, it demonstrates its performance in high-load areas such as gears and shafts. This product is referred to as a dry lubrication film and has effects similar to those achieved with conventional greases and oils. While greases and oils generally provide higher lubrication performance, the dry lubrication film does not require replenishment like greases or oils. Due to its high performance and maintenance-free characteristics, it is widely used in automobiles, construction machinery, and industrial robots. The basic composition of the coating agent consists of a resin binder with molybdenum disulfide dispersed in it. Depending on the type of binder used, it is possible to alter the performance of the paint.
