Research & Development

"Surface Treatment Laboratory"aiming to develop next-generation technologies

In order to continue to be a technology proposal-oriented company, we spent three years preparing and establishing the "Surface Treatment Laboratory" that enables research and development of cutting-edge plating technologies.

Research facilities boasting an area of 580m²
Research laboratory

As a foundation for the new Surface Treatment Laboratory, beakerwork is mainly conducted in this laboratory.

Prototype room

Possibilities exploited from research with scaled-up facilities are guided to stable production in this prototype room.

Surface modification room

Not only plating but also new films as well as new methods and other new-generation surface treatments are researched in this surface modification room.

Environmental test room

Environmental performance evaluation is a critical element in making technology needed by society.


Developed technologies
Eco-friendly plating

Technologies for plating films not containing environmental toxins and eco-friendly plating processes have been developed.

Tin reflow plating Original development

This plating technology having been originally developed as "lead-free" solder plating is highly environment-responsive. It excels in solderability and whisker suppression, and has a solid record of mass production.

Features:
- Ability to suppress whiskers
- Suppression of heat discoloration after installation
- Good solderability
- Processability to center carrier items

Monocrystal tin plating Development by IAG collaboration

This plating technology, which can be said to be the ultimate measure against whiskers, has been developed with the certification of "supporting industry" by the Ministry of Economy, Trade and Industry. This can be applied to all sorts of plating methods.

Features:
- High ability to suppress whiskers
- Good solderability
- Low insertion force (50% reduction in comparison to tin reflow plating)

Hexavalent-chromium-free zinc plating Original development

Our eco-friendly trivalent chromium conversion treatment having been introduced ahead of other companies has a solid record of more than 15 years. This can be applied to unichrome, colored, black, and various other appearances.

Features:
- High environmental responsiveness
- Excellent bactericidal property and corrosion resistance
- Solid working record
- Applicability to a wide variety of appearances


Plating for poorly platable materials

Technologies to plate materials that are said to be unplatable or poorly platable have been developed.

Plating for magnesium Development by IAG collaboration

Being certified as a new partnership by the Ministry of Economy, Trade and Industry, we have succeeded in developing a technology to add a highly corrosive-resistant film to magnesium-based materials, which are lightweight and suitable for recycling, so as to compensate for their shortcomings.

Features:
- High corrosion resistance
- Eco-friendly process
- All sorts of plating possibilities

Plating for fine particles Original development

This technology to plate each one of nano- and micro-sized carbon, resin, and metallic fine particles contributes to development of new functional materials, etc.

Features:
- Applicability to carbon, resin, and various other materials
- Applicability to nano-sized particles
- All sorts of plating possibilities

Plating for graphite Development by IAG collaboration

High plating adhesion properties can be secured even under a thermal-resistant environment of 900°C by this special technique having been developed with the certification of "supporting industry" by the Ministry of Economy, Trade and Industry.

Features:
- High adhesion properties
- High thermal resistance
- All sorts of plating possibilities


Plating having special functions

Technologies for plating films having unprecedented surface characteristics have been developed.

Bamboo silver plating Original development

This original silver plating comes with "hardness" and "flexibility" like green bamboo. Production is possible in batch type and hoop type.

Features:
- High bending adhesion properties
- High hardness (low aging degradation)
- High productivity (hoop plating)
- Partial plating possible

Porous nickel plating Original development

Porous surface conformation increasing the surface area is realized by controlling "precipitation." Surface roughness and specific surface area are considerably improved by this nickel plating.

Features:
- Improved surface roughness
- Increased specific surface area
- High surface smoothness


Gold plating for precision components

Technologies that can lead to resource saving in expensive noble metal plating, such as gold and silver, as well as cost saving have been developed.

Spot plating Original development

By this technology, only necessary sections are plated with noble metals. This technology contributes to reducing manufacturing costs and also saving resources by omitting noble metals from unnecessary sections.

Features:
- Plating for only necessary sections possible
- High area accuracy (dimension error 0.25mm or less)
- Saving of noble metal resources (1/10 in our comparison)
- Applicability to molded items

Nickel barrier plating Original development

This gold and nickel plating technology with high area accuracy in a stripe state enables nickel barrier formation even in complex shapes.

Features:
- Stripe plating
- High area accuracy (Ni width 0.5±0.2mm)
- Plating for end faces possible
- Applicability to molded items
