Why not achieve downsizing with ultra-fine wires with a diameter of 0.01 mm (10 μm)? Corrosion-resistant and durable plating, and even rods, pins, and bars are possible!
This document introduces technology that allows for wire drawing down to φ0.01mm (10μm) and electro-polishing down to φ0.0025mm (2.5μm). It also presents techniques for "plating" and "straightening" these wires. All product manufacturing equipment that maximizes our unique manufacturing know-how is developed in-house. Furthermore, not only technical skills but also the craftsmanship of artisans who carefully pass the wire through the die multiple times to create ultra-fine wires, along with the electro-polishing process and quality inspection, are supported by a skilled group of "Tokusai Masters" who have cultivated their techniques over many years. We can work with difficult-to-process materials such as tungsten and molybdenum, as well as stainless steel, beryllium copper, and nickel-titanium alloys. Additionally, we can manufacture rods, pins, and bars cut from fine wires. It is also possible to perform "plating" along the entire length of the wire. **Features** - Wire drawing processing down to φ0.01mm (10μm), and further processing down to φ0.0025mm (2.5μm) after electro-polishing. - Continuous plating along the entire length of φ0.005mm (5μm) wire is possible due to our unique manufacturing equipment and processing methods. - In "plating," we can respond to short delivery times while reducing processes, labor, and costs.

Tokushai Co., Ltd. manufactures and sells various metal and alloy wire drawing processes and drawn products (such as cut pins, rods, straightening processes, and flat wire produced by rolling), starting with difficult-to-process materials like tungsten and molybdenum, as well as stainless steel, nickel-titanium alloys, and beryllium copper alloys. Additionally, thanks to our unique plating production line, we can also produce continuously long plated wires. With 70 years of experience in wire drawing (drawing and pulling) technology and the craftsmanship of skilled artisans who create wires so thin they are nearly invisible, we realize a world of ultra-fine wires. Starting with tungsten wire for Christmas light filaments as our founding product, Tokushai has expanded its business alongside the development of the lighting market, including incandescent bulbs, fluorescent lamps, and automotive bulbs. Today, we have broadened our market to include semiconductor testing equipment (probe cards), electronic components, medical devices, and even the aerospace industry, responding to various customer needs.
