Taiyou Kinzoku Industry Co., Ltd.

Consigned processing as experts in metal heat treatment.

We have accepted consigned machine work of metal products, centering on three types of heat treatment i.e., “flame (blaze) quenching (flame hardening)”, “plasma nitriding” and “high-frequency quenching”, as experts in metal heat treatment since our foundation in 1970. Flame quenching technology can be applied to a wide variety of products. We endeavor to rear successors and innovate heat treatment technology, under the facility manager selected as the “Contemporary Master Craftsman”. 90% of the male staff are licensed skilled metal heat treatment workers, although our total number of employees is small.  On a technical aspect, we have developed “TAIYO3S NAITO” treatment technique which does not decrease the corrosion resistance of stainless steel. 


Other presentation

[Company strength]
We have been contributing to many companies, centering on three types of heat treatment, i.e., “flame (blaze) quenching (flame hardening)”, “plasma nitriding” and “high-frequency quenching”, as an expert of metal heat treatment since our foundation in 1970. We have many capable craftsmen, and the Facility Manager, Nobumi Kamimura, was selected as “Contemporary Master Craftsman” by the Ministry of Health, Labour and Welfare in 2009. We also endeavor to train the younger generation, and we employ many certified skilled metal heat treatment workers (90% of our male staff), including those with a special class license.

[Business description]
We carry out consigned machine work of metal products, etc., including high-frequency quenching, flame (blaze) quenching (flame hardening), plasma nitriding (ion nitriding), and shot blasting. We provide the optimum treatment method by changing the flame color, temperature and cooling method for each article according to the shape and material. We confirm hardness and depth of the metal structure by rupture inspection. 

Metal heat treatment processing

[Strength of products/technologies]
As a result of three years R&D, we have created “TAIYO3SNAITO” treatment as nitriding treatment which does not decrease the corrosion resistance of stainless steel, in addition to three types of heat treatment. The treatment has the following characteristics and advantages. “The treatment makes a hardening layer with a surface hardness of 800HV or more (This can be set within the range 800 HV to 1300 HV).” “The treatment improves wear and abrasion resistance without deteriorating corrosion resistance in comparison with existing nitriding treatment.” “The treatment is carried out at a temperature lower than that of ordinary nitriding treatments, and therefore deformation and distortion are further reduced.” “Cost spent for surface treatment such as painting or coating is expected to be reduced because of improved corrosion resistance.” “Cost of manufacture and processing is equal to that of conventional treatment”.  

[Representative's message]
We have devoted ourselves to techniques as a specialized manufacturer of “heat treatment processing” for 40 years or more. The quality of heat treatment cannot be judged from its appearance just as the sharpness of a sword cannot be determined by looks alone. Heat treatment, however, plays an important role in influencing the quality of products. Japanese heat treatment techniques will become increasingly important as a backbone of “Monozukuri (manufacturing)” from now. We will fervently endeavor to establish trust through our invisible techniques while taking over traditional craftsman techniques.

[Company structure for market development/overseas expansion]
We are developing the market by, for example, regularly sending DMs all over Japan, responding to inquiries on our Web site and actively participating in exhibitions and business meetings. We perform business activities by a two-person system, and all members in charge of the activities are a licensed heat treatment skilled worker and can therefore answer customers’ technical inquiries. We consider overseas expansion as a next step activity, and will gradually prepare a system to do so.  

[Market share/Ranking]
Our flame quenching has the highest market share. There are only two companies capable of dealing with various kinds of flame quenching, including us in Japan.

[Awards and media coverage]
Our representative, Seigo Harada, was selected for Technology Management Award of The Japan Society for Heat Treatment (2014).
