By using irregular shapes, we propose "improvement of material yield," "stability of quality," and "enhancement of productivity."
In order to mass-produce copper components implemented in the base, we propose improvements in "material yield," "reduction of mold costs," "quality stability," and "productivity enhancement" by processing special-shaped wire as the material. (1) Improvement of material yield - In the pressing process, scrap is generated around the product, but by processing special-shaped wire as the material, it is possible to significantly reduce scrap. (2) No need for progressive molds as parts can be mass-produced through cutting and bending processes - If short-length cuts are used, cutting blades can be employed, and for bending, processing can be done with bending jigs, thus reducing initial investments such as progressive molds. (3) Quality stability - Continuous processing of already precisely finished special-shaped wire alleviates variations in each shot. (4) Productivity enhancement - By using long special-shaped wire (500-1,000 kg) as the material, continuous productivity is improved. *Regarding the processing steps for components combined with special-shaped wire (cutting, pressing, forming, bending), we would like to determine this through discussions with the customer, our company, or partners. *For more details, please feel free to contact us.

Company information
Since its establishment in 1947, we have been manufacturing and selling steel wire products through drawing and rolling processes, and now we offer integrated production from cold-formed components to metal parts produced by pressing, shearing, and machining. In particular, we excel in the production of deformed coil wire with irregular cross-sections, and our strength lies in our ability to consistently produce unique deformed metal parts utilizing these irregular wires. Compared to powder sintering and precision casting methods used for manufacturing deformed parts, our deformed metal parts produced entirely through plastic processing at Namitei possess excellent toughness, strength, and smooth surface characteristics, making them widely adopted in sliding components and thin-walled deformed parts. To leverage the cost advantages of continuous processing, we propose specifications that mix functional applications and processing characteristics to meet our customers' needs.
