Products and Technologies

Deformed wires

Realized cost reduction

Deformed wire is a wire rod product that is formed by drawing and rolling to form ferrous and non-ferrous wire rods with irregular cross sections.

In particular, NAMITEI manufactures deformed coil wires with superior productivity compared to drawn steel bars. It is a wire rod that has the function of the material itself and has a shape close to the final product.

Deformed parts

Shaped parts utilizing deformed wires with minimal burrs and sagging

In addition to general cold heading, NAMITEI enables more complicated heading by use of deformed wires.

NAMITEI's deformed parts manufactured by cold forging, which is plastic forming, have excellent toughness and smooth surface characteristics, compared to powder sintering and precision casting parts, which are often used to manufacture deformed metal parts,

Control equipment parts

Copper (EV terminal), electromagnetic soft iron (relay iron core)

At NAMITEI, the former process has been modified to improve press forming ability, reducing machining process and eliminating it.

After press forming, in order to guarantee a high-quality product. NAMITEI conducts cleaning, 100% inspection (in the clean booth), vacuum packaging and non-discoloring dry delivery.
