Area of specialty and technology

 ◆ component
    fabrication

We manufacture various electrical coupling parts mainly of motor and generator.
We also handle high-mix low-volume production such as machining process, bending work and welding work.

 ◆ coil winding casting
We have achieved various coil winding and process of pulling and bent wire, mainly a stator coil of an electric motor and generator by a round wire and rectangular wire.
Furthermore, we have achieved auto insulating tape winding to unshielded rectangular wire, bent processing and radius processing after cutoff operation, and also voltage transformer coil winding process.

 ◆ insulation
Various electrical coupling parts and coils, insulating tape winding and also Varnish handling.

 ◆ coil assembly・
    Fabrication

For example a consistent process from coil assembly to fabrication of rotor and stator, we have lots of actual achievement.

 ◆ System Development
Development and sales of software for office and factory management.

 ◆ wire replacing
Disassembly and renewal of degraded induction motor and direct-current motor.

 ◆ precision assembly
Fabrication of motor controlled sensor for vehicle.
Coil assembly, fabrication and near work of a compact electric transformer etc.

 ◆ industrial rubber
    casting

Making all rubber casting products such as rubber packing and rubber casting products with metal fittings. We can get a mold tool when it is necessary.
