We will be exhibiting at the Functional Film Expo 2021 held on July 15-16, 2021.

By simply dissolving the powder in a solvent and drying it, you can obtain a transparent and high-heat-resistant polyimide film!

Kawamura Industries' "KPI-MX300F" is a polyimide powder material that can dissolve in various solvents. The films obtained by dissolving in a solvent and then heating and drying have minimal coloring and high transparency, which is a significant feature. **Features of Kawamura Industries' "KPI-MX300F"** - Can dissolve in various solvents - Produces transparent, high-heat-resistant polyimide films - The resulting films have minimal coloring and high transparency *For property values, please refer to the PDF document or feel free to contact us.*

This is a surface treatment technology that dramatically improves the adhesion of fluororesin films and polyimide films, which have been considered difficult to bond until now.

At Kawamura Industries, we apply plasma treatment to films, metal foils, non-woven fabrics, and more, performing surface modifications such as hydrophilization and hydrophobization. This treatment significantly improves the adhesion of various films and allows for the removal and purification of organic substances from the substrate surface. It can effectively remove residues such as rolling oils that are difficult to completely eliminate with wet cleaning. Additionally, it is possible to bond various materials together without the use of adhesives. **Features of Kawamura Industries' 'Vacuum Plasma Treatment'** - Dramatically improves adhesive strength - Effectively removes rolling oils and organic substances, purifying the surface - Enables adhesive-free bonding of various materials - Selects suitable gas types and plasma treatment conditions for each project - Treatment effects last for an extended period - Continuous processing is possible with roll-to-roll technology *For more details, please refer to the PDF document or feel free to contact us.*

Metal thin films are formed from roll to roll on various substrates.

At Kawamura Industries, we perform sputtering processing of copper, nichrome alloy, and chrome onto various substrates. If greater adhesion is required, we can suggest using our plasma treatment as a pre-treatment. **Features of Kawamura Industries' Sputtering Processing** - Roll to roll sputtering processing → Example of copper sputtering: thickness 0.1 to 0.2 μm - Capable of continuous film formation with different metal types → Multiple cathodes used - Supports sputtering of copper, nichrome alloy, and chrome *Please consult us regarding target materials other than those listed above. *For more details, please refer to the PDF materials or feel free to contact us.

In civil engineering sites, there are many instances where temporary roads, access roads, heavy machinery work yards, and material storage areas use ground plates. While conventional steel plates are practical, they can sometimes fail to leave a lasting impression when it comes to the appearance of the site and conveying the company's initiatives. Hyper CLT ground plates are civil engineering materials that utilize wood CLT. As ground plates with the texture of wood, they can be used as a substitute for steel plates, for mud prevention, ground protection, and ensuring pedestrian pathways. By introducing them in visible areas such as site entrances, morning assembly locations, and around break areas, it becomes easier to create an impact that differs from traditional sites. The 5×10 plate weighs about 230 kg, and the 5×20 plate weighs about 460 kg, making them lightweight and easy to handle even with small machinery, which helps reduce construction burdens. They also offer advantages such as glare reduction, noise reduction, and environmental considerations unique to wood, making them suitable for innovative public works projects. Registered as a Ministry of Land, Infrastructure, Transport and Tourism NETIS technology "TH-250021-A," they are recommended for companies aiming to create a distinctive impression at their sites. We can also provide consultation for small lot introductions and suggest usage methods tailored to site conditions. Why not add a clear change to your civil engineering site with these new wooden ground plates?

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.

In facilities operating nurse call systems, we have made the bed exit sensor wireless, allowing it to notify in conjunction with the nurse call system. By simply connecting the mat sensor "Foldable Thin Matt-kun," the body movement call "Ugo-kun," and the wheelchair body movement call "Ayumi-chan" to the transmitter HB-RS, you can make the bed exit sensor wireless. The infrared sensor "Just Place Pole-kun" has the transmitter HB-RS built-in. This helps prevent accidents caused by falls, slips, or wandering, contributing to the efficiency of medical operations. 【Features】 ○ Wireless conversion by simply connecting existing sensors to the transmitter HB-WSK. ○ The bed exit sensor notifies wirelessly in conjunction with the nurse call system. ○ Up to 5 transmitters can be registered with a single receiver. ○ The communication distance between the transmitter and receiver is approximately 10 meters. ◎ For more details, please contact us or download the catalog.

[To the owners of parking lots and parking lot construction companies] "I’m worried about not colliding with pedestrians when exiting the parking lot..." Among vehicle entrances to parking lots, stores, residences, and factories, those particularly facing sidewalks or roadways are expected to pose risks of dangerous incidents such as collisions with pedestrians or between vehicles. To alleviate such concerns, Hotron proposes a [Vehicle Exit Warning Sensor] that detects vehicle departures using various sensors and alerts the surroundings with LED lights and buzzers. The device consists of a simple configuration of "Sensor" + "Controller" + "Switching Power Supply (24V)" + "LED Rotating Light." *Please note that a separate control panel is required to include the controller and switching power supply (24V) when using the exit warning system. *We kindly ask that customers arrange for the switching power supply (24V), LED rotating light, control panel, circuit breakers, etc. Since it can be retrofitted, it can also be used for existing parking lot entrances. We hope this will contribute to safer vehicle passage for everyone. ◎ For more details, please contact us or download the catalog.
