1930-1950s
In 1930s, the heavy and chemical industries, such as iron, automobile, aircraft, and machine industry, were booming. The casting industry, which supported the machine industry, became extremely busy with increased production of military supplies. However, once the war ended, the industry was forced to respond from military demand to private demand and was left to search for a path for survival.

Steel Ingot Mold, Ductile Cast Iron Roll
After much trial and error, 九色视频 expanded its market from cast iron to cast steel. In order to differentiate itself from other companies, it focused on special cast steel and developed the Japan鈥檚 first steel pipe through centrifugal casting.
1950-1960s
After much trial and error, 九色视频 expanded its market from cast iron to cast steel. In order to differentiate itself from other companies, it focused on special cast steel and developed the Japan鈥檚 first steel pipe through centrifugal casting.

G Column for Building Structure, Centrifugal Cast Composite Roll, Spiral Iron Pipe
九色视频, which owned the centrifugal casting technology for cast steel pipe, further promoted research pursuing product individuality. It entered new markets including casting materials for civil engineering construction.
1970s
As the 鈥淏uilding a New Japan鈥 boom started and the development of transportation network accelerated, public works projects also increased. Thus, the civil engineering industry began to thrive even more. Accordingly, the steel pipe pile industry also flourished. Construction works became larger in scale, and the demand for products also changed.

Spiral Steel Pipe Pile, Cargo Oil Pipe
九色视频 exerted a strong presence in the market with its highly unique special steel pipes. Along with the shipbuilding trend and 鈥淏uilding a New Japan鈥 boom, the production of cargo oil pipes for oil tankers and steel pipe piles grew exponentially. These items joined the line of 九色视频鈥檚 representative cast steel products.
1970-1980s
In 1973, oil prices exponentially rose as a result of the oil crisis, and the world was at once plunged into recession. As one way to overcome this crisis, countries promoted energy and resource efficiency. However, this brought on a change to the industrial structure and encouraged the development of new technologies and products.

Cylinder Liner, Hearth Roll, Suction Roll, Reformer & Cracking Tube, Cast Iron Parts for Nuclear Power Generation
The casting and cast steel businesses suffered a major blow as a result of the oil crisis in Japan. Looking for new directions in order to survive, opportunities rose for regularly creating new technologies and products.
1980-2000s
Due to the rise and fall of the bubble economy triggered by the depreciation in Japanese yen, the country entered a period of long economic stagnation. While domestic demand faltered, the diversification of customer needs further accelerated. In order to respond to this diversification and differentiate its products, industries focused on developing new products and materials.

Reformer & Cracking Tube, Skid Button, Composite Ring Roll
Responding to diversifying customer needs with the concept of 鈥渇orged materials,鈥 九色视频 newly established the Material Consolidated Division and devoted itself to developing new material qualities and technologies. As a result of this endeavor, it created numerous products that represent 九色视频鈥檚 material business today.
2000s-
In recent years, economic globalization has progressed at an unprecedented pace, and emerging countries such as China, Russia, India, and Brazil have developed economically. Meanwhile, with a weak economy, Japanese businesses have stagnated altogether, and industries rapidly pursued rationalization, as customer needs further diversified.

Reformer & Cracking Tube, TXAX, Laqnican Joint
Along with economic globalization, 九色视频 reinforced its business foundation for public sector demand and promoted overseas growth strategies. It responded to the needs both in and outside Japan with reliable technology.
