The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact to the base material. Repairs can be carried out in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.

● This is a leak testing device for small electronic components that does not use fluorinated inert liquids (PFAS-free). ● There is no longer a need for unstable visual confirmation through liquid immersion testing. It adopts a quantitative testing method that allows for stable pressure leak testing. ● It is a tabletop leak testing device specifically for gross leaks, with accuracy equal to or greater than that of liquid immersion testing. ● The detectable range is approximately 1×10⁻² Pa·m³/s to 1×10⁻⁶ Pa·m³/s (varies depending on the target product). ● It is suitable for sealed structures ranging from a few millimeters to a maximum of 80 × 70 mm.

On September 11, 2025, AC Tasarim, a cable blade manufacturer, and our company signed a sales agency agreement for Japan. This was also announced in the company's press release and on social media. Founded in Turkey in 2003, AC Tasarim manufactures flexible EMI cable shields (copper braid), polyester braid, meta-aramid braid (Nomex cable sleeves), flat copper braid busbars/ground braids, all AA59569-coded copper braids, and released AeroBraid in 2025, the world's lightest EMI braid. All manufactured copper braids are certified to military standards. AC Tasarim products hold key certifications including VDE/VG certification, German Federal Armed Forces certification, NATO NSN coding, AS9100 quality certification, and JOSCAR certification. Cable braids and EMI shielding products, essential for wire harnesses in the aerospace and defense industries, are becoming increasingly difficult to source as demand rises. TC Tasarim products are stocked by manufacturers and distributors to ensure quick response times.

Starting from September 22, 2025 (Monday), we will begin accepting orders for five new lineups tailored to various applications in the "N-SELECT" series of transport vehicles. In this new development, we will introduce the following five models that maintain the basic performance of the traditional N-SELECT while addressing more specialized needs: SC (Super Carrier) - Based on the traditional N-SELECT, this model is specialized for transporting immobile and accident vehicles. It is ideal for the automotive maintenance and towing industry. RC (Racing Carrier) - Designed with a gentle loading and unloading angle, this model is perfect for transporting sports cars and lowered vehicles. TP (Transporter) - A standard model optimized for the transportation of general passenger vehicles, suitable for a wide range of industries. ONE (Single Vehicle Loading Model) - A simple and efficient design dedicated to loading one vehicle. Recommended for small-scale transport and individual entrepreneurs. RS (Rescue) - A single vehicle loading model equipped with a crane, enhancing its capability to respond in accident scenes and tight spaces. With these lineups, N-SELECT evolves into a product group that meets a wider variety of on-site needs. We will continue to promote product development that reflects the voices from the field as the "preferred transport vehicle."
