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.

● The production time for casting prototypes can be shortened! Since model production is not required, the time needed to create prototypes, which previously took about a month, can be significantly reduced. ● Model costs can be reduced! By directly producing sand molds from 3D data, there is no need for model production costs. If changes to the model are necessary, they can be addressed by modifying the 3D data. ● Similar products with different shapes and dimensions can be prototyped simultaneously! With one molding process, different products with similar shapes or varying dimensions can be molded at the same time. This allows for the verification of multiple types in a short period.

We will be exhibiting at the "New Manufacturing and New Services Exhibition for Small and Medium Enterprises" from December 16 (Tuesday) to 18 (Thursday), 2025. Please feel free to stop by our booth. We look forward to meeting everyone.

Thank you very much for your continued support. Donaldson Japan Co., Ltd. will be closed during the following period: From April 25 (Saturday) to May 6 (Wednesday). Inquiries made during the closure will be answered sequentially after May 7 (Thursday). We sincerely apologize for any inconvenience this may cause. Thank you for your understanding and cooperation.

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact on the base material. Repairs can be carried out 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. ◎ If a detailed technical explanation is needed, please contact us.
