Spin riveting is a riveting process that can be used for joining dissimilar materials and for movable parts.

"Spin riveting" is a riveting process that involves applying pressure with a rotating insert on the tip of the rivet. By evenly applying pressure to the rivet, it allows for processing with less force, ensuring precision and maintaining rigidity. Additionally, it can be used for joining dissimilar materials and movable parts. Our company achieves high productivity and quality through semi-automated operations using spin riveting. 【Assembly Processing Achievements】 ◆ Automotive parts, components for nursing robots, printing machine parts, electronic device parts ◆ Construction waterproofing materials ◆ Hairpins for wigs *We accommodate riveting and assembly processes tailored to customer needs.

Spin riveting, which ensures cost reduction in joining engineering and high rigidity, can also be used in movable parts.

"Spin riveting" is a processing method that joins materials by deforming rivets through pressure while rotating. By applying pressure while rotating, it is possible to evenly distribute force on the rivet, allowing for processing with less force than conventional press riveting that only uses pressure. In particular, the "spin riveting" using rivets, as shown in this video, is adopted for many functional parts because it has high rigidity while also being usable in movable components. There are various shapes for the finished rivet joint, which can be selected based on the choice of insert. The "Yamagata" shape introduced in the video is a standard shape among "spin riveting." **Advantages of Riveting Processing** - High precision at low cost - Strong rigidity in joints - Ideal for joining movable parts - Capable of joining dissimilar materials For more details, please download the catalog or contact us.

"Spin fastening" is a processing method that joins materials by applying pressure and deforming rivets using a rotating insert. By applying pressure while rotating, it is possible to evenly press the rivets, allowing for joining with less force than conventional press fastening, which relies solely on pressure. Particularly, the "spin fastening" using rivets, as demonstrated in this video, is adopted for many functional parts because it can be used in movable components while maintaining high rigidity. There are various shapes for the finished appearance of the fastening area, which can be selected based on the choice of insert. The "bowl-shaped" form introduced in the video is rounded without corners compared to the "serrated" shape. It is a fastening shape processed using custom inserts tailored to the size of the fastening area. **Advantages of fastening processing:** - High precision at low cost - Strong rigidity in joints - Ideal for joining movable parts - Capable of joining dissimilar materials For more details, please download the catalog or contact us.

CLT, which has been widely adopted in the construction field, is now expanding its applications into the civil engineering sector. The "Hyper CLT Mats" are civil engineering CLT products that utilize wood CLT as temporary materials. Traditionally, steel plates have been the mainstream choice for temporary roads, access routes, and heavy machinery yards. The Hyper CLT Mats introduce a new option of "wood" to that market. The 5x10 mats weigh approximately 230 kg, making them lightweight and easy to install and remove with small machinery, with a maximum capacity of 40 mats on a 10-ton truck. They also have advantages in terms of workability and transportation efficiency. Moreover, they offer added value that can only be achieved with wood, such as glare reduction, noise control, CO2 fixation, and consideration for aesthetics. This product is expected to be a new proposal for not only construction companies but also building material firms, lumber companies, and material trading companies. It is a registered technology with the Ministry of Land, Infrastructure, Transport and Tourism under NETIS, with the registration number "TH-250021-A." The use of wood is not limited to construction anymore. The utilization of Hyper CLT Mats is expanding as a new market that connects civil engineering and wood.

In civil engineering sites such as mountainous areas and construction sites, it may be necessary to use wooden boards on slopes or inclined access roads. Hyper CLT boards are civil engineering materials utilizing wood CLT, which can be laid not only on flat ground but also on sloped terrain. They can be used for temporary roads, access routes, heavy machinery entry paths, and measures against muddy conditions, creating a driving environment that takes advantage of the unique surface characteristics of wood. The 5×10 board weighs approximately 230 kg, and the 5×20 board weighs about 460 kg, making them lightweight and easy to install and remove even with small machinery, which is a notable feature for maneuverability in narrow sites. This wooden board is registered as a technology under the Ministry of Land, Infrastructure, Transport and Tourism's NETIS system as "TH-250021-A," and can also be utilized for safety measures and innovative ideas in public works.

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