NHV Corporation will hold a free English-language webinar on electron beam technology on September 8, 2026. It will introduce the features of electron beams, how the equipment works, and the new EB-XW product. Advance registration is required.
NHV Corporation will hold an online invited lecture on July 14, 2026, about the effects and applications of electron beam irradiation in SiC semiconductors. Topics will include the relationship between irradiation-induced defects and carrier lifetime, as well as applications to solid-state quantum sensors using SiC.
NHV Corporation will begin holding free online seminars on electron beam processing in July 2026. The program will include invited and previously delivered lectures and will be hosted via Zoom Webinar. See the official page for details.
NHV Corporation will host an online invited lecture on developing an efficient technology to decompose fluoropolymers using electron beam irradiation. Compared with conventional high-temperature thermal processing, the technology can reduce energy consumption by about 70% and support recycling for resource and environmental benefits. The seminar will present results and future prospects.
NHV Corporation will exhibit at wire 2026 in Düsseldorf, Germany, from April 13 to 17, 2026. Its booth will showcase electron beam irradiation technology and application examples, and provide an opportunity to meet engineers and decision-makers from around the world.
NHV Corporation has signed an agreement to provide its electron beam irradiation equipment (EPS) condition monitoring system to a major tire manufacturer's factory in Vietnam. The system collects and analyzes operating data in real time, detects abnormalities, and helps keep production lines running reliably. The company aims to expand globally and deploy the system on all equipment.
NHV Corporation has published a catalog for its new EB-XW product. The catalog can be downloaded and provides information about electron beam irradiation equipment.
NHV Corporation will hold a seminar on January 29, 2026, covering electron beam sterilization and material modification. Experts from Osaka Metropolitan University and Kyoto Institute of Technology will discuss fundamental technologies and applications. Participants may attend online or tour the venue.
