An alternative to screws, welding, and adhesive bonding! Capable of joining dissimilar materials, with numerous applications in automotive parts, etc. *Video available.

"Rivet processing" is a type of joining method that connects multiple parts and is used in many industrial products, including automobiles. Among these, our company's specialty, "spin riveting" using rivets, is adopted in many functional components because it offers high rigidity while also being usable in movable parts. Additionally, it serves as an alternative to joining methods such as screws, welding, and adhesives, providing the significant advantage of securing movable parts without loosening. You can also find it in everyday items like scissors and wheels. 【Advantages of Rivet Processing】 ● High precision at low cost ● Strong rigidity in joints ● Recommended for joining movable parts ● Capable of joining dissimilar materials *Video "Understanding Rivet Processing in 60 Seconds" is available below. *For more details, please download the catalog or contact us.

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. Assembly videos are available on our company website. For more details, please contact us.

Joining movable parts, joining dissimilar materials, and achieving high precision and rigidity with spin riveting!

"Rivet processing" is one of the methods for joining multiple materials together. The "spin riveting" technique we employ applies uniform pressure to the tip of the rivet using a rotating insert, allowing for processing with less pressure. The advantages of spin riveting include high rigidity, the ability to join dissimilar materials, and suitability for joining movable parts. Rivets are available in various sizes, and the shape of the rivet can be selected. - The finished shape of the rivet can vary based on the choice of insert. - Inserts can accommodate shapes such as "mountain type," "flat type," and "bowl type." - Rivet sizes range from φ1 to φ14 mm, and we can accommodate over 30 different materials. [Assembly Processing Achievements] - Automotive parts - Parts for nursing care robots - Construction waterproofing materials - Printing machine parts - Hairpins for wigs - Electronic device parts We offer rivet processing and assembly tailored to our customers' 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.
