Proposal/Case Study | Hollow for "Weight Reduction and Labor Saving"
All items are made to order, and there are no standard products available.
We propose lightweighting through the hollowing of irregular wires using pipe coil material.
Namitei specializes in the production of shaped coil wire using coil wire materials, and has produced a large number of shaped wires for automotive parts as well as for plants and civil engineering. Recently, in the automotive industry, "weight reduction" has become an important improvement theme as the industry moves towards electrification due to environmental issues. In this context, our company is working on the development of hollow shaped wires using pipe coil materials. Although the material costs increase by switching to pipe coil materials, the weight reduction offsets this increase, resulting in cases where we have successfully achieved weight reduction at nearly the same price depending on the specifications. Additionally, beyond weight reduction, products have also been commercialized using shaped core materials for lance (cutting rods).

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.
