A dissimilar metal joining solution that contributes to improving the quietness of railway vehicles.
In the manufacturing of railway vehicles, achieving both lightweight design and high quietness is essential. Particularly when joining different materials, suppressing vibration and noise becomes crucial. Traditional methods often require pre-drilling and construction from both sides, which can complicate the process and increase weight. Our "Multi-Material" solution enables the joining of dissimilar materials such as aluminum and steel plates without pre-drilling and with construction from only one side, addressing these challenges. This contributes to the reduction of vehicle weight and improvement of quietness, providing a comfortable ride. 【Application Scenarios】 - Joining of interior and exterior panels of vehicles - Joining of structural components made from different metals - Application in areas where quietness is required 【Benefits of Implementation】 - Improved quietness through reduced vibration and noise - Enhanced fuel efficiency and driving performance due to weight reduction - Increased productivity through process simplification

Company information
Since our founding, our company has been manufacturing screws such as nuts and bolts, along with related products. Screws are functional components that join various parts together to create finished products, serving as the "supporting role." Although they may seem unremarkable, we have continuously made tireless efforts with a spirit of innovation and originality, and as a result, we are deeply grateful to have become a company that can contribute to society, albeit on a small scale. As you know, screws are functional components that gather a wide variety of parts to create finished products. Some products are following a path of advanced lightweight and compact design, while others are becoming more luxurious and larger. On the other hand, the technology for assembling parts is advancing towards high-speed, labor-saving, and even automation. Our company is committed to making continuous efforts in technological innovation, product development, and modernization of equipment to provide technologies and products that can respond to any of these situations. We sincerely ask for your continued support and encouragement.
