[Technical Issue] What causes grease to flow in high-temperature environments?

エムアンドエム エムアンドエム
In high-temperature environments such as die-casting molds, there are many cases where, despite using high-temperature grease, "the grease flows away during operation." This phenomenon occurs not simply because the grease melts, but because the oil components separate under high temperatures, making it difficult for the lubricating components to remain in the moving parts. As a result, this leads to issues such as: - Oil splattering to the surroundings - Insufficient lubrication - Increased frequency of reapplication In high-temperature environments, it is not only the heat resistance temperature that matters, but also whether the lubrication state can be maintained under high temperatures, which becomes an important point in grease selection. Detailed causes and considerations for selection are organized technically in the attached document.

Hyper CLT flooring panel

Civil engineering site considerate of the neighborhood | Hyper CLT flooring

  • NEW
  • PRODUCT

In civil engineering sites, there are many instances where temporary roads, access routes, material storage areas, and pedestrian pathways use wooden boards. In residential areas, near schools, hospitals, and stores, the noise from construction, glare, and the appearance of the site can affect the impression on nearby residents, so consideration for temporary materials is required. Hyper CLT boards are civil engineering materials that utilize wood CLT. As wooden boards, they can be used as an alternative to steel plates, for muddy ground measures, ground protection, heavy machinery scaffolding, and worker pathways. The unique texture of wood provides a softer impression compared to metal plates, contributing to the improvement of the site environment. Additionally, they can be used as materials for proposals that address neighborhood concerns and environmental considerations, such as reducing metal noise, suppressing glare, and fixing CO2. The 5×10 board weighs approximately 230 kg, and the 5×20 board weighs about 460 kg, making them lightweight and easy to handle even with small machinery. As a registered technology with the Ministry of Land, Infrastructure, Transport and Tourism under NETIS "TH-250021-A," they are also recommended for innovative ideas and safety measures in public works. We encourage you to consider creating civil engineering sites that take into account the surrounding area. We can also propose locations and quantities tailored to site conditions. Please feel free to contact us for material requests or consultations on implementation. They can also be utilized in urban construction and private projects. Don't hesitate to reach out.

Impressing the site with the presence of wood | Hyper CLT flooring

  • NEW
  • PRODUCT

In civil engineering sites, there are many instances where temporary roads, access roads, heavy machinery work yards, and material storage areas use ground plates. While conventional steel plates are practical, they can sometimes fail to leave a lasting impression when it comes to the appearance of the site and conveying the company's initiatives. Hyper CLT ground plates are civil engineering materials that utilize wood CLT. As ground plates with the texture of wood, they can be used as a substitute for steel plates, for mud prevention, ground protection, and ensuring pedestrian pathways. By introducing them in visible areas such as site entrances, morning assembly locations, and around break areas, it becomes easier to create an impact that differs from traditional sites. The 5×10 plate weighs about 230 kg, and the 5×20 plate weighs about 460 kg, making them lightweight and easy to handle even with small machinery, which helps reduce construction burdens. They also offer advantages such as glare reduction, noise reduction, and environmental considerations unique to wood, making them suitable for innovative public works projects. Registered as a Ministry of Land, Infrastructure, Transport and Tourism NETIS technology "TH-250021-A," they are recommended for companies aiming to create a distinctive impression at their sites. We can also provide consultation for small lot introductions and suggest usage methods tailored to site conditions. Why not add a clear change to your civil engineering site with these new wooden ground plates?

Metal Crack Repair: MS Method for Repairing Cracks and Fractures in Machinery Equipment

  • NEW
  • PRODUCT

Metal cracks are one of the concerns in equipment maintenance operations. Conventional welding methods for repairs can change the base material around the crack due to heat, leading to residual stress and deformation, which always carries the risk of "crack recurrence" and "secondary damage." Hinode Waterworks Equipment Co., Ltd.'s "Mechanical Stitching Method" is a new technique that allows for metal crack repairs without applying heat. By using special bolts and reinforcement plates, the crack is physically removed without affecting the base material at all. Repairs can be made even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. For more details, please contact us or download the catalog.
