Thin-walled coating for electric wires, medical tube manufacturing, coating of metal and resin wires, etc. We provide extruders that accommodate various materials, wire diameters, and thicknesses.
Our company develops and manufactures coating devices for electric wires and optical fibers, medical tube extruders (extrusion molding machines), and functional coating devices for wire ropes. With advanced tension control, stable extrusion, and temperature control in various sections, we can accurately mold thin films and accommodate a wide range of wire diameters from φ0.09mm (core 0.03mm) to thicker sizes. We can also handle coating with various resin materials such as general-purpose resins, fluorine resins, super engineering plastics, and UV-curable resins. We conduct detailed discussions with our customers and provide proposals and realizations tailored to their needs, from the establishment of coating lines to modifications of existing lines and suggestions for individual key components. 【Features】 ■ Wide range of needs from small lot products to mass production ■ Capable of high-speed processing at 1200m/min ■ Proven track record in the electric wire, medical tube, and wire rope industries, as well as in the tire and belt industries *For more details, please refer to the materials available for download in PDF format.
