High heat resistance and high hardness chrome plating "Cloamore"

The hardness is approximately twice that of hard chrome plating (Hv1800)! Introducing the world's first amorphous chrome plating.

The world's first amorphous chrome "Cloamore" is a chromium-based alloy coating that contains 2-4% carbon, boasting ultra-high hardness and excellent wear resistance.

Are you looking for a surface treatment that has high hardness, corrosion resistance, and heat resistance to replace DLC?

Cromall is a chromium-based alloy plating that contains 2-4% carbon, offering high hardness and excellent wear resistance. Unlike conventional hard chrome plating, it is crack-free and has fewer coating defects like those found in DLC films, resulting in superior corrosion resistance. (The corrosion rate in hydrochloric acid is one-third that of hard chrome plating, and can be reduced to one-sixth with heat treatment.) Compared to DLC films, which begin to degrade at around 300°C and lose adhesion, Cromall maintains stable adhesion and demonstrates good adhesion even at high temperatures. It is also possible to treat inner surfaces where DLC processing is not effective.

【Free samples available!】We solve your concerns about wanting a thin, high-hardness surface treatment for semiconductor packaging molds with "Cloamore"!

Here is an example of a sealing mold used for semiconductor components. [Challenge] We received a request from a manufacturer to perform a surface treatment that is as thin and high-hardness as possible for a sealing mold used for semiconductor components, as well as to extend the lifespan of the base material. [Proposal] We introduced our "Cloamore." [Result] They evaluated the precision and wear resistance, and subsequently requested a complete set including the mold for the resin flow path. The wear resistance improved, and the lifespan of the base material was extended.

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. We will resume normal business operations on Friday, August 15. We appreciate your understanding during this time and apologize for any inconvenience caused.

"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.

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.
