"Complete sealing of electronic components in just a few dozen seconds. Ideal for waterproofing, dustproofing, and insulation!" Hot melt molding, which is gaining attention for waterproof sealing of electronic components, utilizes thermoplastic adhesives in low-pressure insert molding to achieve environmental protection such as waterproofing and dustproofing for electronic components like mounted circuit boards. Compared to traditional two-component potting and conformal coating, sealing is completed in an extremely short time, leading to an expansion in its adoption as a sealing technology. We propose a sustainable hot melt made primarily from natural fatty acids. At the Matsumoto Processing Lab, nine hot melt molding machines are installed, and you can observe the actual process of hot melt sealing electronic components. Customers interested in visiting are encouraged to inquire.

"Complete sealing of electronic components in just a few dozen seconds. Waterproof, dustproof, and insulated." A sealing method for electronic components that replaces potting = hot melt molding.

By replacing potting, we achieve cost reduction and miniaturization. Hot melt molding has the following advantages, and the transition from two-component potting is progressing. - Extremely short cycle time In hot melt molding, sealing is completed in just a few seconds. - Possibility of miniaturization and lightweight design Since it allows for direct insert molding of electronic components, there is no need for a case, and the high degree of freedom in shape enables miniaturization and lightweight design. - Sustainability The PA-based hot melts we handle are primarily made from natural vegetable oils, offering excellent environmental benefits. We have compiled materials on how potting and hot melt molding differ. Please download the materials. *For the "cost reduction" materials, please view the PDF data from the download.

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.

The "CCS2" is a ceiling-mounted vehicle counting sensor that employs an infrared reflection method. It can detect vehicles in both directions with just one unit, accurately counting vehicles even during traffic jams or when vehicles pass each other. Additionally, this product can be used not only for vehicle counting but also as a sensor for departure warnings. Furthermore, by using a separately sold dedicated remote control, it is easy to reset the sensor alone, switch the counting direction, and change the patterns of the departure warning timer. 【Features】 ■ Angle adjustment is possible up to ±5° ■ Can be installed in locations with high ceilings up to 4m ■ Detection area consists of 40 spots, allowing for wide-range detection ■ The display LEDs are color-coded by direction, making operation confirmation easy.

Many people may have questions like, "What can be done with IoT?" and "What is needed?" upon hearing the term IoT. Through digital communication, it is possible to obtain various information such as flow sensors, valves, circuit boards, and abnormal monitoring that were not accessible with traditional analog control. For example, by monitoring the valve opening, one can detect blockages in the equipment and identify leaks from cumulative flow. This information directly contributes to reducing downtime and improving quality through continuous long-term monitoring and knowledge-based management. Compatible models include those with digital communication via RS485, in addition to traditional analog controls like 0-5VDC and 4-20mA. (Older models such as the 58xxS, MfxxS series, SLA58xxS, and SLAMfxxS series). Even older models that do not support digital communication can be upgraded to the latest mass flow models, enabling digital communication. The dimensions between new and old models are the same, and no wiring changes are necessary. Additionally, we can provide control boxes for data collection from mass flow. This enables a "visualization" of small IoT without making large changes to the equipment.
