High dimensional accuracy in thickness and width of "various flat wires, shaped wires, and round wires."
It is possible to manufacture long flat bars (copper equivalent) with a maximum weight of 400 kg, regardless of thickness or width, without any welded joints. This significantly reduces the time loss required for material changes.
"Various flat wires, shaped wires, and round wires" are products that leverage the flat and shaped processing technology cultivated since the company's inception, making them our specialty and a distinctive feature of our offerings. We process flat and round wires made of copper (C1100), pure aluminum (A1070), aluminum alloys, and square wires made of brass (C2700). 【Features of Flat Wires】 ■ Large coil weight without welding ■ No "return" on the edges, allowing for freely selectable shapes ■ High dimensional accuracy for thickness and width (accuracy within ±3/100 mm for thickness and ±5/100 mm for width) <Examples of Applications> Functional components for electrical equipment (connector pins, contacts, terminals, etc.), automotive parts, and medical masks, etc.

basic information
<Features of Our Flat Wire> ■ Large coil weight without welding We can manufacture long flat wire (copper equivalent) with a maximum weight of 400 kg without any welding points, regardless of thickness or width. By using this long flat wire, the time loss associated with material changeovers is significantly reduced, allowing for a substantial increase in productivity compared to using conventional round or flat wire. Even during long hours of continuous operation, variations in materials and dimensions are minimal, greatly reducing the risk of mold damage. When using continuous molds, material yield is significantly improved. ■ No "return" on the edges and shape can be freely selected Compared to round wire, our flat wire has no "return" on the edges, and we can manufacture edge shapes according to your preferences. This allows the edges to be directly used on the sides of components, significantly improving material yield and contributing to cost reduction. ■ High dimensional accuracy for thickness and width We can finish with a precision of ±3/100 mm for thickness and ±5/100 mm for width. 【Corporate Philosophy】 ■ Flexible structure adaptable to various types, small quantities, and short delivery times ■ High quality comparable to large corporations ■ Unbeatable low costs ■ Strong information and technical capabilities to quickly realize user needs
