Tsukada Riken Industry Co., Ltd.

We focus on advanced plastic plating technology and eco-friendly manufacturing. Here is our 5 main technologies.

① Decorative Plating
We plate plastic parts for cars, home appliances, and daily goods to make them look beautiful by creating many different styles, such as chrome, metallic, mirror, or matte finishes. This helps improve the brand image and value of the products.

② Functional Plating
We provide plating that adds "functionality," not just good designs.
Common examples include:
- Electromagnetic Shielding: Blocking electromagnetic noise and signals.
- Corrosion Resistance: Preventing rust.
- Wear Resistance: Protecting against scratches and friction.
These are used in many fields, including home appliances, electronics, and car parts.

③ Plating on Difficult & Special Materials
We have expert technology to plate materials that are usually "difficult to plate." Specifically, we can apply high-quality plating to materials like 3D-printed resin, magnesium alloys, and carbon nanotubes.

④ Circuit Board (PCB) Plating
A plating for circuit boards used in smartphones and computers. By accurately adding metals like gold, silver, or tin to the surface, we help electricity flow better and connect parts more securely. Our technology supports high-tech electronics, and our fully automated lines allow us to handle both small and large production orders.

⑤ Surface Treatment Technology
This is the process of adding both "beautiful design" and "functionality" to plastic. We can create a wide range of looks, from shiny mirror finishes to matte textures. We can also make parts harder to scratch or able to block electromagnetic waves. This technology is essential for improving the quality of car interiors and home products.

Our headquarters is located in Komagane City, Nagano Prefecture, a town with views of the two Japanese Alps!
