We will exhibit at Interop Tokyo (Autumn) from September 9 (Wednesday) to September 11 (Friday), 2026 at Makuhari Messe.

A low-pressure molding method that replaces 2-liquid potting, achieving improved production efficiency and miniaturization. Case studies will be presented at Nepcon Japan in September 2026!

Hot melt molding is a low-pressure molding method aimed at waterproofing, dustproofing, and insulation of electrical components. In traditional two-component potting methods such as urethane and epoxy, production delays due to curing time and the need for securing workspace were challenges. This method allows the resin to rapidly cure in just a few seconds to several tens of seconds, enabling the product to flow to the next process immediately after sealing, thereby improving production efficiency and reducing costs on the manufacturing line. It is used in automotive electrical components, sensors, and IoT devices, and is expected to be adopted in markets such as drones and e-bikes for waterproofing measures in the future. 【Features】 ■ Cures in just 30 seconds, completing full waterproof sealing of components ■ Improved efficiency of the entire production process by replacing two-component potting ■ High design flexibility through mold forming using thermoplastic resin * For more details, please download the materials or feel free to contact us. 【Exhibition Information: Internepcon Japan Autumn】 Venue: Makuhari Messe Dates: September 9 (Wed) - September 11 (Fri), 2026 Exhibition lineup: Hot melt adhesives for low-pressure molding, dedicated low-pressure molding equipment for hot melt, etc. ★ We sincerely look forward to your visit! ★

Waterproof and dustproof components for drone electrical equipment 【Hot melt low-pressure molding sealing】 The hot melt molding sealing method, which boasts high reliability in protecting automotive electrical components, is applied to drones.

Drones, which are being utilized in various fields starting from agriculture, forestry, and fisheries, have recently expanded their applications to logistics. One of the challenges as the areas of use broaden is reliability in harsh environments such as rain and sand. Therefore, Matsumoto Processing proposes a highly reliable electronic component protection method, developed through waterproofing and dustproofing automotive and aircraft parts, specifically for drones: the hot melt low-pressure molding technique. Main Features: ★1 High Reliability: The hot melt and molding sealing method has over 20 years of proven performance in waterproof and dustproof applications for automotive and aircraft parts, boasting high reliability. ★2 Compact and Lightweight: As it involves mold forming, there is great freedom in shape, allowing for smaller and lighter sealing compared to potting with two-component sealants. ★3 High Production Efficiency: Cooling and solidification occur within seconds in the mold, completing the sealing process quickly. ★4 Sustainable: The sealing material is an environmentally friendly material primarily made from plant-derived natural fatty acids. Matsumoto Processing can flexibly accommodate initial small-scale prototypes. Please feel free to contact us.

The hyper CLT sheets come in two sizes: 5×10 and 5×20. Key points for selection include the size of the site, the installation location, the heavy machinery used, and the frequency of replacement. The 5×10 sheet measures approximately 1.5m × 3m and weighs about 230kg. It is easy to handle even with small machinery, making it suitable for sites where partial installation is desired, such as worker pathways, around rest areas, material yards, and temporary parking lots. A 10-ton truck can carry up to 40 sheets, which also enhances transportation efficiency. On the other hand, the 5×20 sheet measures approximately 1.5m × 6m and weighs about 460kg. It can cover a large area with a single sheet, making it suitable for long access roads, temporary roads, and spacious heavy machinery work yards. It is also characterized by its ability to reduce seams. In some cases, combining both sizes can be an effective approach. The hyper CLT sheets are civil engineering CLT materials utilizing wood and are registered with the Ministry of Land, Infrastructure, Transport and Tourism under the NETIS technology "TH-250021-A." Choosing the right size according to site conditions can enhance workability and usability.

SPACECOOL Co., Ltd. announces that Nikkei Kinzoku Act Co., Ltd., part of the Japan Light Metal Group, has introduced the "SPACECOOL Roof Shade" on approximately 4,000 square meters of the roof at its Kamihara factory. This introduction aims to improve the hot environment within the factory during the summer, reduce the risk of heatstroke for employees, and create a workplace environment where employees can work with peace of mind, which will also contribute to future recruitment efforts. - Comment from Kazunori Kiyosawa, Group Leader of the Equipment Group at Nikkei Kinzoku Act Co., Ltd. Kamihara Factory We believed that measures against heat in the factory are essential for protecting employee safety. While considering measures that could be implemented without stopping factory operations, we learned about SPACECOOL. After comparing and verifying it against heat-insulating paints and other options, we confirmed that SPACECOOL had the highest effectiveness. We also felt that being able to experience the installation work firsthand and carry out repairs ourselves afterward is a significant advantage. As temperatures are expected to rise in the future, we aim to create a workplace environment that prevents heatstroke and will continue to work on measures against heat.

Metal cracks are one of the concerns in equipment maintenance operations. Conventional welding methods for repairs can change the base material around the crack due to heat, leading to residual stress and deformation, which always carries the risk of "crack recurrence" and "secondary damage." Hinode Waterworks Equipment Co., Ltd.'s "Mechanical Stitching Method" is a new technique that allows for metal crack repairs without applying heat. By using special bolts and reinforcement plates, the crack is physically removed without affecting the base material at all. Repairs can be made even 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 or download the catalog.

Japan is among the top 10 countries in the world with frequent earthquakes. The 2020 White Paper on Land, Infrastructure, Transport and Tourism has also reported an increase in the probability of significant earthquakes occurring. For the Nankai Trough earthquake, the probability of an earthquake with a magnitude of 8 to 9 occurring within the next 30 years is estimated to be 70 to 80%. At Hotron, we recommend the introduction of seismic devices for earthquake measures in buildings and equipment. The seismic device 'HK-2' is a product that automatically performs various controls that have been pre-set when it detects strong shaking equivalent to a seismic intensity of 5 lower or higher. For example, it can automatically execute actions such as: "Open automatic doors and gates to secure evacuation routes and access for emergency vehicles" "Transmit signals to the control room and stop facility equipment" "Unlock the keys to locked lockers" "Automatically play voice guidance" ◎ For more details, please download the materials or contact us.
