◆Yoshida SKT Co., Ltd.◆ NEW "What is welding? An explanation of one type of resin welding, heat plate welding, and non-stick surface treatment" has been published.

We will also introduce non-stick surface treatments that are essential for solving the disadvantages of various types and methods of melting and heat plate melting.

■What is Resin Welding Resin welding is one method of joining resins using heat. ■Types and Methods of Welding - Ultrasonic Welding A method that uses ultrasonic vibrations for joining. - Vibration Welding A method that uses frictional heat generated by vibrations for joining. - High-Frequency Welding A method that uses self-generated heat from high frequency for joining. - Laser Welding A method that generates heat using laser light for joining. - Heat Plate Welding A method that melts materials using a heated plate for joining. ■Advantages and Disadvantages of Heat Plate Welding Heat plate welding can accommodate a wide range of part sizes and can securely weld even three-dimensional shapes, making it suitable for joining components that require airtightness. On the other hand, it cannot be used if electronic components are present, and there are disadvantages such as excess material when welding, resin sticking to the heater, and stringing. ■Surface Treatment to Prevent Resin Sticking and Stringing to the Heat Plate One method to prevent resin sticking to the heat plate and stringing, which are among the disadvantages, is surface treatment.

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.

Adopted for a project on the promotion, demonstration, and commercialization of advanced wastewater treatment facilities using the Indian national rotary fiber unit, a pilot plant with a capacity of 1000 m³/day will be constructed within a wastewater treatment facility in Bengaluru, South India. Verification will be conducted for one year starting from June 1, 2023, and will conclude on May 31, 2024. Throughout the year, all of India's stringent discharge standards will be met, and a wastewater treatment manual will be created and promoted in India.

The "HM-S6" is an embedded park sensor that detects vehicles through changes in magnetic flux and can respond to various situations from passing to stationary. It can be used for the opening and closing of the input doors at waste treatment plants, as well as for gates where vehicles pass and in outdoor parking applications. It can also be installed on rebar and steel plates. 【Features】 - Resistant to the effects of natural environments such as rain, snow, temperature changes, and geomagnetism. - Protection rating IP68 reduces the risk of water ingress. - Ten times the load capacity compared to conventional embedded park sensors (according to our comparison). - Can distinguish between vehicles even when they pass continuously, one by one. - Can be installed on rebar and steel plates. *For more details, please refer to the PDF document or feel free to 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.

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 affecting the base material with heat. 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.
