Coating of the inner surface of the pipe, fine (ultra-fine) parts.

Avoiding the occurrence of non-plating in the central part of the inner surface of the pipe with our unique manufacturing technology!

Plating on pipes, fine (ultra-fine) parts, and springs is part of our surface treatment technology. Plating tends to be difficult to adhere to the central part of the inner surface of pipes, leading to areas without plating or uneven plating. Our company avoids these issues through unique manufacturing techniques, including mesh application. Additionally, plating is possible even for fine (ultra-fine) products, fine springs, and products with a high number of turns. *For more details, please refer to the PDF materials or feel free to contact us.

Plating for bag hole parts that are easy to assemble and adhere to.

Shapes that are prone to non-plating can avoid it through unique manufacturing techniques such as netting!

The plating of bag hole sections, which are easy to assemble and have a tendency to stick, is part of our surface treatment technology. Plating on bag hole sections can achieve an aspect ratio of about 1:10, and we avoid non-plating through our unique manufacturing techniques, including mesh attachment. Shapes that are easy to assemble or tend to stick together, such as flat or L-shaped products, are also managed to avoid non-plating through our unique manufacturing techniques, including mesh attachment. *For more details, please refer to the PDF materials or feel free to contact us.

Electroplating, precipitation hardening treatment, analysis (cross-section polishing)

Introducing products that can be unraveled during plating and netted plating to avoid non-plating.

Net plating, precipitation hardening treatment, and analysis (cross-section polishing) are each part of our surface treatment technology. Net plating is a method of plating products by placing them in a fixture called a net basket. By shaking and loosening the products during plating, similar to the process of making handmade paper, this method avoids areas without plating. Additionally, precipitation hardening treatment is performed on beryllium copper material in a non-oxidizing heating furnace, and in the analysis (cross-section polishing), the product is solidified with resin, allowing for the analysis of defects through cross-section polishing. *For more details, please refer to the PDF document or feel free to contact us.*
