Irrax wires have excellent heat- abrasion- and flame-resistance, and are used for wiring in electronic and other devices.
Wire harnesses enable reduction in size, weight, and width, and are used as assembling wire for signals and power in automobiles, railcars, industrial and OA equipment, home appliances, PCs and other electronic devices.


Flexible flat cables or ribbon cables, or SUMI-CARD are developed for internal wiring of electronic and electric devices that require compactness and high-performance. The cables have flexibility and sliding property, and are applied widely as a critical component in dense implementation.


The wiring material has copper circuit printed on extremely thin insulator film.
FPC (Flexible Printed Circuit) contributes to reduction in size, weight and cost of multi-layered and dense electronic devices, and is available in small lots.


SUMI-TUBE has excellent mechanical properties including high-resistance to water, corrosion, and heat, electric insulation and shape memory. It is used for protection of coverings on in-car wire harnesses, brake pipes, etc.
SUMI-TUBE is printable insulating tube and shrinks by heating in the internal direction.


Lubrite, or sintered component with high-precision and high-intensity is an excellent material for manufacturing mass produced parts for automobiles, home appliances, OA equipment, composite material/parts and for molding of special shapes.


Used for optical fibers and devices, optical LAN, optical communication system, medical equipment, and image transmission, the cables deliver superior performance in high-speed transmission, capacity enlargement, miniaturization and weight saving, long-distance transmission, and insulation.

マグネットワイヤー MAGNET WIRE

Used for electrical equipment in automobiles, home appliances, electronic devices, various types of rotating machine, static equipment (transformers, coils), the magnet wires are adhesive, and resistant to heat, press molding, and abrasion.
