When the pull wire dies industry started in Japan, pull wire machines as well as dies were imported, where the dies had the mesh plate shape, a forge plate (steel plate) with 10~20 holes. For its size and weight, Japanese people had difficulties in using it, hence flat dies 2" X 3" X 10" with three holes and flat dies 2" X 3" X 4"with a single hole were necessary. Steel dies using materials such as high carbon or high chrome (known as red bore) are used for copper or iron pull wire, while dies containing tungsten (known as black bore) are used for hard steel pull wire.
Hamada Hanjiro Shop (Hamada Steel Dies Shop) was established. Started as authorized dealer of steel dies from Yasurai Steel Industry (now, Hitachi Metal Corporation). Consequently, the Domestic Steel Tools Manufacturing was established to processing and finishing forge dies, and receiving more than 500 tons of CRD supplies from Hitachi Metal Corporation.
Became a recognized plant authorized by Japan Steel Wire and Cable Industry Association to be granted its investment, as a compliment for its superior materials.
Toyo Dies Industries of Sakurajirushi was established, to expand and maintain its market for Sakura no. O (known as Hamada no. O) from Hamada Dies Shop.
It started by adding the pull wire diamond tools which just passed the test to its commercial products besides the ultra hard alloy dies already in market.
Received a certificate of longtime contribution and new technology development in dies tools category from Hitachi Electric Wires Corporation.
A new plant for ultra hard alloy was constructed and started to operate within the city of Toyohashi.
A new plant was constructed and started to operate in Indonesia.
Sintering of alloy (Tungsten Carbide) had been successfully performed for the first time in Indonesia.
