We know precious metal materials inside out, and develop dental and industrial materials.

We process and refine precious metal bullion, such as gold, silver, platinum, and palladium. Our mainline business is to develop and manufacture precious metal dental materials, including ceramic materials and organic materials. Our precious metal bullion products include nanopowders and functional metal materials. Our industrial material products have been used as evaporation materials and sputtering targets for LED chips and semiconductors. We also propose micro-miniature parts and other new uses of precious metals by adding various metals. Our proposals include sensors and semiconductor inspection probes that make use of the excellent corrosion resistance, electrical conductivity, and workability characteristics of precious metals.


Other presentation

[Company strength]
Our company was established for the business of trading precious metal bullion. We have been steadily expanding our field of business to precious metal dental materials, dental ceramic materials, dental resin materials, and industrial precious metal materials. We have confidence in our development capabilities for dental ceramic and dental resin materials, which are completely different from precious metal materials. This is because of our experience in independent R&D and commercialization. We are now often selected as one of the few precious metal manufacturers with a product site in West Japan from the perspective of business continuity plans (BCPs).

[Business description]
We started our corporate history by trading precious metal bullion. Our company manufactures and sells precious metal dental materials, machines precious metals for electronic materials, and recycles and refines precious metals. We independently develop, manufacture, and sell ceramic and organic dental materials. We process electronic materials from nanopowders to meter-size materials. We even handle functional metal materials to expand our field of business.

Dental materials and precious metal materials

[Strength of products/technologies]
Precious metals originally have excellent properties such as high corrosion resistance, electrical conductivity, and workability. It is effective to alloy several metals to impart mechanical strength and other characteristics while making use of such characteristics of precious metals. Adding precious metals to base metals is expected to improve corrosion resistance. Our company possesses particular technical strength regarding alloying and alloy processing based on our many years of experience in handling dental precious metals. Market prices of precious metal bullion have been soaring, and alloy materials where precious metals are partially replaced with base metals are attracting attention. We focus on quickly giving shape to customer needs, and we can manufacture a very small quantity of products as samples.

[Representative's message]
We have been improving our technologies for dental care development. We have cultivated alloying and alloy processing technologies by handling dental alloys. We will learn your needs through J-GoodTech and apply our technologies to industrial products to make a contribution to the broader development of the industrial world.

[Company structure for market development/overseas expansion]
We have a bullion department at our Osaka head office as our sales site. Our engineering staff will visit customers from our Kochi Factory for technical inquiries. We are expanding our business for dental materials other than precious metal products in about 20 countries throughout the world. We have a special department in the company for overseas business. We also have an English website to accept inquiries from overseas companies.

[Market share/Ranking]
Our company ranked third in the dental precious metal industry in 2014 with a market share of 17.8%. Among these products we were forecast in 2015 to be number one for precious metal alloys for ceramic baking with a market share of 37.1%. We were forecast in 2015 to rank number two in the dental hard resin industry with a market share of 16.5%. We were forecast to rank number one in 2015 in the industry of dental resin blocks for CAD/CAM with a market share of 27.3%.
