New case site "Special Nut and Color Manufacturing.com" is now OPEN!

A must-see for those struggling with construction method changes! Packed with tips for VE/VA proposals specialized in metal nuts! *Free technical handbook available!

Cold forging offers higher dimensional accuracy and surface flatness compared to conventional forging processes. Our company utilizes this technology to provide high-precision and cost-effective screw components. By transitioning from other manufacturing methods to cold forging, there are various benefits such as cost reduction, shorter delivery times, and improved quality. This time, we have prepared a document featuring the characteristics of "custom metal nuts" and product examples based on the cold forging know-how we have cultivated over many years. It is full of hints for method conversion and VE/VA proposals! Please take a look! [Contents] ◎ Applications and overview of custom metal nuts ◎ VA/VE proposal examples We will introduce various types, including flange types, irregular shapes, and non-ferrous metal types. Leave the prototyping to mass production of metal nuts to Mazda!

Cold forging has higher dimensional accuracy and surface flatness compared to general forging processes. Our company utilizes this technology to provide high-precision and cost-effective screw components. This time, based on the cold forging know-how we have cultivated over many years, we have prepared a document featuring the characteristics and product examples of "custom metal collars." Additionally, for those interested, we will present a "Cold Forging Cutting-Free 'Process Transition' Technology Handbook," which introduces basic knowledge of cold forging and the advantages of replacing other methods.

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/

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.

"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]. ↓ ↓ ↓

Explosion-proof motors available in stock We will deliver within 7 days to meet your delivery schedule. 【What is an explosion-proof motor?】 In factories and plants, flammable gases and vapors are present. When these mix with air and come into contact with an ignition source, an explosion or fire can occur. This motor is designed with measures to eliminate such ignition sources. 【Available stock models】 ■ Pressure-resistant explosion-proof motors, explosion-proof grade d2G4 - Foot-mounted type, output 0.4 to 3.7 kW, 4 poles - Flange type, output 0.4 to 0.75 kW, 4 poles ■ Increased safety explosion-proof motors, explosion-proof grade eG3 - Foot-mounted type, output 0.2 to 0.75 kW, 2 and 4 poles - Flange type, output 0.2 to 0.75 kW, 2 and 4 poles

As part of the "Hometown Ibara Future Creation Human Resource Development Project," we welcomed local elementary and middle school students to the special summer program "Ibara Job Exploration Tour 2025," a collaboration between the Ibara City Chamber of Commerce and the Corporate Branding Committee. We conducted a presentation that clearly and enjoyably introduced how our technology supports society, allowing the children to learn about the appeal of manufacturing and the significance of working while interacting with actual devices and products. Through this initiative, we hope to deepen our connection with the community and nurture the curiosity of the children who will carry the future. We sincerely thank everyone who participated, as well as all those involved in planning and organizing the event.
