High dimensional accuracy in thickness and width of "various flat wires, shaped wires, and round wires."

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.

Yamakin, a manufacturer of flat copper, brass, aluminum, and zinc wire and horizontal winding electric wire.

Yamakin, a manufacturer of flat copper, brass, aluminum, and zinc wire and horizontal winding electric wire.

Supports various types, small quantities, and short delivery times! We have a proven track record of deliveries to major companies such as Mitsubishi Electric, Toshiba, and Sumitomo Heavy Industries!

Yamakin started as a non-ferrous metal sales business in 1916 and has since developed into a manufacturer of flat copper, brass, aluminum, and zinc wire and coiled wire. To accommodate a variety of products in small quantities with short delivery times, we change our production line six to seven times a day at peak times. Since the dimensions of materials change with temperature fluctuations, temperature management of the rolling mill is a crucial factor. Additionally, the rolling mill was a machine purchased by our predecessor in the United States, which means that all our wire products are manufactured through rolling. We are the only company in Japan that manufactures exclusively through rolling, giving us an advantage in offering a variety of products in small quantities with short delivery times. The introduction of the industry's first continuous patch system has reduced lead times to one-third to one-fourth. This has further accelerated our differentiation from competitors in terms of short delivery times. In the future, we will shift our focus from copper wire to aluminum wire, which has raw material costs less than half that of copper. Although aluminum has a conductivity that is 62% that of copper, we will address this by increasing the wire diameter. Since the rolling mill introduced by our predecessor was designed for aluminum, we possess significant know-how in aluminum wire production, and the rising prices of copper have also boosted demand.

No edges and free shapes! 'Various flat wires, shaped wires, and round wires'

No edges and free shapes! 'Various flat wires, shaped wires, and round wires'

It is possible to finish with a precision of ±3/100 millimeters in thickness and ±5/100 millimeters in width!

Yamakkin is a manufacturer of flat wires and coiled wires made of copper, brass, aluminum, and zinc. Our "various flat wires, shaped wires, and round wires" are products that we excel at and are characterized by the flat and shaped processing technology we have cultivated since the company's inception. Their applications range from functional components for electrical equipment (connector pins, contacts, terminals, etc.) to automotive parts and medical masks, and 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】 ■ No "return" on the edges and the shape can be freely selected Compared to bars, there is no "return" on the edges, and we can manufacture the edge shape according to your preferences. Therefore, the edges can be directly used as 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.
