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.

JOHNAN has updated a webpage summarizing the selection points to solve various challenges in large-scale processing (quality maintenance, short delivery times, costs). This article introduces the challenges faced in large-scale processing based on years of knowledge and experience, as well as the key points for choosing the optimal contractor that balances quality and short delivery times. If you are looking for a reliable contractor, please make use of our "Large-Scale Processing Solutions." ▼For more details "Large-Scale Processing Solutions to Achieve Product Quality and Short Delivery Times" https://www.johnan.com/solution/process/processing-assembly/post_8.html

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.

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]. ↓ ↓ ↓
