By applying a special treatment to the surface of silicone rubber, we provide three functionalities: prevention of sticking, prevention of dust adhesion, and improved sliding properties. - Unlike conventional painting methods, we can impart sliding properties without eliminating the texture and fine irregularities on the surface of silicone parts. - We can also give a smooth touch to silicone rubber parts. - Black silicone rubber parts tend to attract sebum and dust, making dirt noticeable, and they can be difficult to clean off. However, after our treatment, they can be easily removed.

We will create a component that integrates resin parts and rubber parts. It can also accommodate complex shapes, such as making only part of it rubber. Are you struggling with difficult shapes or insufficient adhesive strength after molding resin and rubber parts, such as with adhesives? Our insert molding technology achieves strong adhesion. We have also realized the integrated molding of difficult-to-adhere PP and silicone rubber.

One method for adding a metallic finish to plastic parts is vapor deposition. While it results in a high-end appearance similar to metal, a significant drawback is the wear of the protective coat. Even when used in products that are intended for long-term use with a metallic finish, they tend to deteriorate and peel off over time. We have achieved a vapor deposition that does not peel by changing the process! Instead of a conventional protective coat, we have dramatically improved wear resistance by providing a thick protective layer through resin molding. - Housing parts - Emblem marks - Corporate logos and more.

• Contract manufacturing

This is an introduction to the dispersion technology of single-walled carbon nanotubes (SWCNT). - Stable production is achieved through proprietary evaluation technology. - By controlling the dispersion energy, dispersion can be tailored according to application. - By quantifying the dispersion state, high-performance various CNT dispersion liquids can be adjusted.
