AMITEI mainly manufactures deformed steel wire,which are widely used in industrial fields such as the electric industry, communications,machinery,shipbuilding,civil engineering,and OA equipment. There are various shapes available including triangular,square,hexagonal,and other are possible according to user requirements. These deformed wires make it possible to omit conventional cutting and other machine processing steps. They can be used as they are,which results in sharp cost reductions. The most advanced technique deformed wires are called "3- division wire." This is used as the pressure-proof layer for optical submarine cable in 1985, "The Third Pacific Ocean Submarine Cable" was installed with optical fiber technology for the first time between Japan and USA. The company participated in this large development project,and developed deformed wire as the pressure- proof layer. The wire is to protect the fine optical fivers installed at the bottom of the Pacific Ocean from the water pressure of maximum 800 atm, and has a 3-division narow pipe shape in which optical fibers are converged and wrapped to form a pipe. High Dimensional accuracy and high strength are required, and high accuracy for 100km lengths of cable as well as the highest quality are also important. In addition to deformed wires, the company has some original products. Recently, "NAMIJET" was developed ot clean in-line long lines and bars with high-pressure water at hight speed. It is highly regarded as an environmentally-friendly product that meets the environmental requirements and regulations. |
