The Amagasaki Plant started in 1981, and was the first to successfully recycle tungsten carbide by pyrometallurgy in Japan, and obtain the ISO9001 and ISO14001 certificates.
Japan is a country without many rare metal mines. Sintered hard metal scraps, used hard metal tools and products, are a precious mineral resource. The collection system and recycling is an important issue that can only be resolved by a shared vision between industry, government, and the citizens. The Amagasaki plant’s cumulative knowhow over the years has gained trust from our customers.
- Dust Collection
1Collection of Scrap Metals
We collect sintered hard metal scraps from sources as different as the automobile industry, general contractors, and machining factories.
We sort the scrap according to the composition of Tungsten, Cobalt and other elemtns.
3Zinc Treatment Process
The sorted scrap goes under the Zinc treatment process and becomes porous.
The output of the zinc process is pulverised in several steps to obtain a uniform particle sizes.
The slurry is dried after the wet pulverisation process to yield our product.
After rigorous quality control analyses, our products are sold and fabricated into hard metal tools.
