Company PR
For about 40 years, we have been producing ductile cast iron (mainly sheaves and wheels), and we are working on opening markets for defect-free thin-walled products as well as demanding machine tool parts (spindle head, etc.) lately. Since you can clean molten metal with our self-developed Kinoshita electric arc furnace, you can minimize damage generation and consistently produce ductile cast iron that is homogeneous to the inside. You can also cast thin-walled products thanks to high fluidity provided by our electric arc furnace. Also, we participate in the development of manganese removal device as a measure for reusing multicomponenting iron scrap (for example manganese, high tensile strength steel). We also propose refining processes combining Kinoshita electric arc furnace and manganese removal device, and design sales.
We supports wide varieties of specs of various sheaves and our services are also available to you with quick turn around time and at low cost even when you are ordering in a non-standard small lot.
We can manufacture thin-walled (from 2mm) ductile cast iron. We also have experiences in producing exhaust manifolds as heat-resistant cast iron product.
