Adhering silicone rubber to silicone rubber with atmospheric pressure plasma! Developed a technology to strongly bond difficult-to-adhere materials quickly without using adhesives.

Achieve excellent painting and coating with atmospheric pressure plasma technology, featuring "adhesion," "optical properties," "reduction of chemical solutions," and "high-speed processing"!

Our company expects to significantly improve the processability of coatings by modifying the surface of materials using atmospheric pressure plasma. Improving the wettability of the coating surface leads to savings in paint usage and the formation of thin films with excellent optical properties. Additionally, our technology allows for the plasma generation of various gases, enabling the production of various radicals within the plasma. 【Features】 ■ Significantly improves the processability of coatings by modifying the surface of materials ■ Improvement of wettability on the coating surface saves paint usage ■ Formation of thin films with excellent optical properties ■ Capable of generating various radicals in plasma ■ Reduces costs and environmental impact associated with chemical treatment, etc. *For more details, please contact us.

Hydrophilization can enhance the wettability of the surface and reduce the surface tension.

Our company offers a technology that uses atmospheric pressure plasma to hydrophilize the surface of materials under atmospheric pressure. Compared to conventional low-pressure treatments, processing under atmospheric pressure allows for easier equipment configuration and enables continuous processing. Furthermore, with the technology to plasma-activate various gases, we can rapidly hydrophilize the surfaces of various materials. 【Features】 ■ Ability to hydrophilize the surface of materials under atmospheric pressure ■ Easy equipment configuration and capability for continuous processing ■ Rapid hydrophilization of various material surfaces through plasma activation of various gases ■ Enhances surface wettability = reduces surface tension ■ Enables penetration of adhesives and enhances capillary phenomena, etc. *For more details, please contact us.

Atmospheric pressure plasma treatment technology for metals and conductive fibers that can irradiate the surface of metals with atmospheric pressure plasma.

Our company offers atmospheric pressure plasma treatment technology for metals and conductive fibers, which can decompose and remove grease that could not be eliminated by organic solvents or surfactants, and generate functional groups such as hydroxyl groups on the surface, allowing for strong chemical bonding with paints and coatings. Plasma treatment can be applied to the tips of needles and edges, and even on the surfaces of metals and conductive materials, without causing discharge damage. 【Features】 ■ Damage-free plasma, so no discharge marks occur ■ Capable of strong chemical bonding with paints and coatings ■ Continuous atmospheric pressure plasma treatment is possible for conductors such as metals and conductive fibers ■ High-speed and efficient plasma treatment is possible for long materials such as metal wires and carbon fibers ■ Plasma treatment can be performed without causing discharge damage, even on the surfaces of metals and conductive materials *For more details, please contact us.

Technoa Co., Ltd. (Headquarters: Gifu City, Gifu Prefecture, Representative Director: Koji Yamazaki) will hold a limited-time summer special event, "Monozukuri DX CAMP," from Saturday, August 9, 2025, to Saturday, August 23, 2025. Small and medium-sized manufacturing companies face challenges such as a shortage of specialized personnel and a lack of know-how and information, which act as barriers to promoting DX (digital transformation). This event will provide a step-by-step approach to "realistic DX," based on the know-how accumulated by Technoa while supporting the DX transformation of small and medium-sized manufacturing companies. It will be structured as DAY.1 to DAY.5, offering an opportunity for skill development during the summer break and supporting the learning and growth of small and medium-sized manufacturers. For more details, please refer to the related link.

Thank you very much for your continued support. We sincerely apologize for the inconvenience, but our company will be closed for summer vacation during the following period. 【Closure Period】 From Saturday, August 9, 2025, to Thursday, August 14, 2025. We will resume normal business operations on Friday, August 15. We appreciate your understanding during this time and apologize for any inconvenience caused.

JOHNAN has released a video that clearly explains the implementation technology for stretchable films, which are expected to be utilized in wearable devices and medical equipment. In the video, you can see how the film, which has excellent elasticity, stretches and contracts. Please check our high technological capabilities and the flexible characteristics that are useful for product development. We hope this will help you generate new ideas in product development. ▼You can watch the video here [Link to the implementation page for stretchable films] https://www.johnan.com/dms/mounting/filmdevic/stretchable/

"Because it's an invisible place, we won't overlook it." Japan's climate is characterized by high temperatures and humidity, and particularly after typhoons and heavy rains, the conditions can be harsh for homes. It's not just the roofs and exterior walls that are affected by rain and wind. The area beneath the floor is actually the most susceptible and often overlooked point. This time, we will explain the "checkpoints for under the floor" that should be confirmed after a typhoon or heavy rain, the "responses" if abnormalities are found, and measures for preventing recurrence. [Table of Contents] ■ Why is underfloor checking necessary? ■ Checkpoints to confirm after a typhoon or heavy rain ■ Responses when damage is discovered ■ Points for preventing recurrence ■ Suggestions from Seihou Products ■ Summary Please be sure to read the [related materials] and [related links]. ↓ ↓ ↓
