Improving the yield of automotive parts by 50%! Introducing case studies for automotive manufacturers.
Namitai's parts and components are active in various fields, from global products to everyday items. The required shapes, strengths, and precisions vary greatly. Based on a unique design philosophy from irregular wire, we respond to diverse needs. For a certain automotive parts manufacturer, when producing parts from expensive materials, the challenge was that conventional punching from standard sheet materials resulted in about 80% material loss. [Customer's Challenges and Issues] ■ Improving yield of high-grade steel parts ■ Conventional methods → When producing parts like the one shown from expensive materials, conventional punching from standard sheet materials results in about 80% material loss... <Example case using high-grade steel> - Ring component: Thickness 3mm × Diameter 280mm - Sheet material: Thickness 3mm × 300mm × 300mm - Material mass: 1.2kg (specific gravity 7.9) - Material loss = 1.0kg *For more details, please refer to the PDF document or 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.
