Multi-material welding (MM-Welding) technology enables smart joining of lightweight materials.
An innovative fastening technology that uses ultrasonic energy to create a positive connection through friction in porous materials, sheet structures, and sandwich materials via injection molding and pressure molding. It secures components using rod-shaped or collar-shaped thermoplastic elements. 【Features】 ■ Achieves significantly stronger connections compared to many other fastening methods. ■ Can be used without pre-setting for tolerances. ■ Does not require additional materials or surface pre-treatment, allowing for waste-free and clean processing. ■ Statistically checks the process to ensure the quality of individual fastenings.

Company information
Tobimoto Sangyo Co., Ltd. was established as a specialized trading company for screws and fastening parts in Tanimachi, Osaka City, shortly after World War II, where many shops dealing in machinery and tools lined the streets. Today, we have built over 75 years of history in the Osaka Machinery Wholesale District (commonly known as the Machinery District) located in Higashi-Osaka City, a town of small and medium-sized enterprises. Screws and fastening parts are used in various industries as the unsung heroes behind the scenes. They may not be very noticeable, but they are essential products without which assembly cannot take place. We take great joy and pride in having specialized in these screws and fastening parts for many years. Our ability to continue our business activities over the years is thanks to our customers and all the stakeholders who support us. We wish to maintain this sense of gratitude and continue to build trust with our customers in the future. With the mission of “providing the best solutions for all our customers,” we will continue to work together as a team to contribute, albeit modestly, to the development of our customers and society. We kindly ask for your continued support.
