Hokuriku Roka Co., Ltd.

Manufacture of special surface treatment agents used for the composite surface treatment of metals

Our company manufactures deburring agents, sliding improvement agents, and modification agents used for post-machining surface treatment and other purposes. Our products are used for the surface treatment of titanium eyeglass frames and also medical stents and catheters. As the number of domestic and overseas customers is increasing, we are actively acquiring patents to protect our products. We now have patents for agents to remove burrs generated by metal machining, to improve the sliding properties of alloy products, and to modify product surfaces.


Sales Pitch

Metal surface modification treatment agent

Other presentation

[Company strength]
Our company can independently develop, manufacture, and sell characteristic products meeting customer needs. In particular, we can perform small-quantity production for niche markets that major chemical manufacturers cannot handle. Flexibility is our advantage. We have acquired licenses for the poisonous and deleterious manufacturing business and the general poisonous and deleterious sales business, and carry out manufacturing to sales under an integrated production system.

[Business description]
We develop and manufacture special surface treatment agents and sell them directly or through agencies.
Our main products are:
1. Deburring agents that remove oxide films and fine burrs generated during the machining of titanium, stainless steel, carbon steel, and other metals
2. Sliding improvement agents that improve the smoothness of metal surfaces
3. Modification agents that modify board surfaces to improve adhesion at coating or plating
4. Other industrial chemicals

Chemical industry: Manufacture of chemicals

[Strength of products/technologies]
We used to protect our conventional products by know-how, but as the market is expanding from local areas to further afield in and outside Japan, we have been actively protecting products by acquiring patents since 2003. We have a total of three patents for agents to remove burrs generated by metal machining, to improve the sliding properties of alloy products, and to modify product surfaces. Two patents are pending for products that we developed for the electronic parts industry.

[Representative's message]
In the last two years, we participated and exhibited our products at Messe Nagoya 2013 and 2014 in Japan and the Manufacturing Trade Fair in Taiwan. These exhibitions enabled us to start doing business with major companies and Taiwanese companies, as well as with an agency based in Taipei City, Taiwan. We will exhibit our products again this year.

[Company structure for market development/overseas expansion]
In 2010, we hired a Chinese speaker, who is now working as a liaison for China by translating various reference materials and conducting publicity activities. In preparation for smooth sales in Taiwan, we have arranged a sales agency. The field of electronic parts is growing remarkably. We exhibit our products at domestic and overseas exhibitions and trade fairs to introduce our surface treatment technologies to companies in the field. We hold demonstrations and supply prototypes to let customers witness the actual effects. We will acquire new customers through these publicity activities.

[Market share/Ranking]
Market share in the eyeglass titanium frame industry; 90% in Japan and 20% outside Japan
