Case Study of Irregular Shape Line Utilization | Improvement of Yield for High-Quality Steel Parts by Switching from Plate Punching
For heat-resistant stainless steel and titanium! Unlike punching from sheet materials, which tends to produce material loss, using shaped wire results in less waste and is expected to improve yield.
At Namitei, we propose product specifications that match our processing characteristics while leveraging the applications and functions of our products, aiming for cost-effective manufacturing. Please feel free to consult us from the design stage. When producing parts like those shown in the diagram from expensive materials such as heat-resistant stainless steel or titanium, there was a problem where approximately 80% material loss occurred due to punching from standard sheet materials. In response, we proposed "creating flat coil components from irregular wire." We manufactured flat coil components from trapezoidal irregular wire with a thick outer side. After processing, the cross-section deformed flat with the outer diameter side stretching. If the specifications of the assumed case are followed, an improvement in yield of about 50% can be expected. [Assumed case using alloy titanium material] ■ 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.
