Nihon Platec Co., Ltd.

Our metal surface treatment is used by major automobile manufacturers. 

Our main business is metal surface treatment. Our company has been accumulating plating insight and experience since our establishment in 1949. This allows us to provide optimal solutions to various customer needs, including electroplating, chemical plating (electroless plating), chemical conversion coating, and passivation treatment. We have handled various materials such as iron, copper, and aluminum in response to customer needs, and accepted both small and large works to expand our business. Our processed articles have been delivered to Honda Motor, Toyota Motor, Yamaha Motor, Nissan Motor, and Toshiba Medical Systems. We were selected for listing in 300 of Japan's Vibrant Monozukuri (Manufacturing) SMEs by the Ministry of Economy, Trade and Industry, and Small and Medium Enterprise Agency in 2009. 


Other presentation

[Company strength]
Our company possesses barrel plating and suspended plating equipment. We provide all kinds of surface treatment, including zinc plating, galvanizing, zinc-iron alloy plating, tin plating, copper-tin plating, copper plating, nickel plating, silver plating, gold plating, and iron plating. We also offer chemical treatment, manganese phosphorous-based chemical conversion treatment, and surface washing for large parts. We have a workshop for prototype development called “Yumezukuri Mekki Kobo: Nasusanroku” to provide plated prototypes. Customers can also join the workshop to develop technology for prototype plating and mass production. 

[Business description]
We provide metal surface treatment (plating), such as electroplating, chemical plating (electroless plating), chemical conversion coating, and passivation treatment. Our surface treatment can be applied to any metals, including iron, copper, and aluminum in any size. We also focus on quality and the environment, which is why we obtained ISO 9001 and ISO 14001 certification. We have four company vehicles to ensure that deliveries in neighboring areas (Tochigi Prefecture or Fukushima Prefecture) satisfy the expected arrival time. 

Surface treatment (plating)

[Strength of products/technologies]
Iron plating and tin plating technology for aluminum materials are the distinctive characteristics of our company. Applying iron plating can impart a hard, durable surface to soft, lightweight, heat-conductive aluminum material. Applying iron plating to aluminum engine pistons or aluminum die parts for resin molding allows us to take advantage of aluminum’s characteristic heat conductivity and lightness. This makes these parts and products sufficiently durable for their intended purpose. Tin is a soft material that can be used with soldering, so its applications for sliding seal parts and electric parts are increasing. We have an ongoing joint research project with Utsunomiya University and other institutions.

[Representative's message]
Our company is a dedicated plating service provider that applies treatment to metal. We accept all kinds of metals for plating and surface treatment regardless of the size. Plating has evolved for passive purposes such as rust prevention for metals, but it can also be used for active purposes. It can be used for making an alloy with other metals, or for making use of the slidability of the plating material. It can dramatically change the properties of the plated material, even in extremely small amounts. We are not aware of issues that need to be addressed because we do not directly supply products to the market. However, we believe we can come up with ideas if you let us know what properties you desire.

[Company structure for market development/overseas expansion]
Plating parts for new products is usually difficult with an existing technology, and often requires joint R&D. Our company starts from joint development of prototypes before moving on to mass production, so we have a prototype development department called “Yumezukuri Mekki Kobo: Nasusanroku” for that purpose. Customers can actually enter this workshop to conduct joint development from the prototype making phase to mass production phase.

[Market share/Ranking]
Many of our customers are automobile or electric appliance-related companies, and our parts are mostly delivered to Tier 1 companies of major automobile manufacturers.
