Webinar on E-mobility Manufacturing (May 26)

We present materials featuring "laser material processing" such as cutting and welding in automobile and battery manufacturing.

Our company is a manufacturer with over 50 years of history and achievements in the production of "laser oscillators" used in equipment and devices both domestically and internationally. In automobile manufacturing, laser technology has also begun to be utilized in various areas, and we are developing laser oscillators and laser processing machines that meet more advanced demands. We are currently offering a document titled "Laser Processing Guide for Automotive and Battery Manufacturing," which clearly introduces the benefits and applications of "laser processing" as well as our products. [Contents of the document (excerpt)] - Main applications in automobile production - Laser welding processing - Laser hardening and overlay processing - Laser processing of Li-ion batteries - Introduction of Coherent products We are also offering a separate booklet titled "Laser Welding Guide." *For more details, please refer to the document. Feel free to contact us with any inquiries.

• Welding Machine

Numerous achievements in automotive parts such as airbag and glass cutting, welding of SUS pipes and gear wheels! Examples for EV and battery parts are also included!

In the manufacturing sector related to e-mobility, where excellent technological innovation is required, there is a demand for new processing methods that offer very high precision and reproducibility, while simultaneously reducing costs is also an essential requirement. At Coherent, we propose suitable laser processing solutions for these challenging issues. *For more details, please refer to the PDF document or feel free to contact us.*

Sekiguchi Iron Works Co., Ltd. will exhibit at the "Environmental Industry Expo 2025" held at S-Bird in Iida City, Nagano Prefecture. This exhibition aims to pave the way for a sustainable future from the local community. It is a trade fair for environmental-related industries originating from the Minami-Shinshu region of Nagano Prefecture. Our company will introduce next-generation solutions for reducing environmental impact and effectively utilizing energy, including our "smokeless small incinerator" and "stove," along with product panels and case studies. No pre-registration is required, and admission is free. We sincerely look forward to your visit.

Recently, fine bubbles, which are tiny bubbles smaller than 100 μm and are referred to as "fine bubbles," have attracted attention in various fields such as the environment, agriculture, food, fisheries, and medicine, due to their ability to impart various functions to liquids. Fine bubbles are classified into two types based on their size: microbubbles and ultrafine bubbles. Recently, there has been a growing interest in ultrafine bubbles, which have a lifespan of several weeks to months. However, listening to the voices of researchers and users reveals some skepticism, which has become one of the issues hindering the spread of fine bubble technology. On the other hand, we have challenged the elucidation of the stabilization mechanism of ultrafine bubbles from a new perspective by enabling the control of number density exceeding 10 billion particles/mL without pressure or concentration operations using our ultrafine bubble generation technology. In this seminar, we will provide a fundamental explanation of fine bubble technology, including the basic physical properties, characteristics and functions, device technology, measurement and evaluation methods, and case studies, to promote research and utilization of fine bubbles based on a correct understanding.

Sekiguchi Iron Works Co., Ltd. will exhibit at the "Minami-Shinshu Environmental Messe 2025" held at S-Bird in Iida City, Nagano Prefecture. This exhibition will be held simultaneously with the "Environmental Industry Trade Fair" taking place the day before. It will be held over the weekend, with many family-friendly events planned. We encourage those who usually find it difficult to visit to take this opportunity to come. Our product exhibition area is located about 10 minutes from the venue. We sincerely look forward to your visit.
