Ring gears transmit the power of the starter motor to the crankshaft when the engine is started. Due to the addition of idle reduction functions in recent years, a greater level of durability and quality is required.

A component mounted next to the engine in a hybrid vehicle. It suppresses engine noise and vibrations. It is in the form of an assembled mass ring and plate.

These parts are used in automatic transmission cars. They connect the engine to the torque converter. Ring gears are installed on the outer circumference.

These parts are used primarily in manual transmission cars. They connect the engine to the clutch. Due to the vibration suppression applied in recent years, there has been an increase in dual mass flywheels with internal dampers.

These rings are installed on torque converters. They are machined with screw holes for installation on drive plates. These rings are installed on torque converters, in order to maintain the moment of inertia.

A component mounted next to the engine in a hybrid vehicle. It suppresses engine noise and vibrations.

These rings are used to maintain the strength of the housing. There is a notch along the shape of the housing on the inner diameter.

These products are installed on flywheels and drive plates. They are missing teeth in a specific location, which allows the rotation of the engine (crankshaft) to be detected.

Heat is applied to the wire while heating to shape a round cross section into an irregularly angled cross section. This absorbs the phenomenon of the inner thickness increasing and the outer thickness decreasing, when a ring is formed (bent). Therefore, a uniform thickness is maintained after processing is completed.

Cold-processing is used during cooling to shape a round cross section into an irregularly angled cross section. This absorbs the phenomenon of the inner thickness increasing and the outer thickness decreasing, when a ring is formed (bent). Therefore, a uniform thickness is maintained after processing is completed.

3-phase AC generator mainly used in automobiles. Brackets, rotors, stators, and similar components are combined to produce fully-complete alternators. These alternators are delivered to automobile manufacturers after in-house performance tests, appearance inspections, and packaging.

Gear cases used in starters. Machining and metal press-fitting of die-cast products are used. The yoke and magnetic switch parts are assembled together.

Stoppers used in starters. They are assembled into the armature section. Machined using a lathe with a bar feeder.

Power module cases used in inverters for battery electric vehicles. Flanges and cooling fins are joined by use of friction stir welding.

Racks for high-pressure fuel pump position control.

Field coils for starters. Wound flat wires are connected by fusing with connecting wire. Brushes and terminal leads are also installed by fusing.

Contact case assemblies used in starters. Part that is assembled together with the magnetic switch parts and receives electricity from the battery. Retaining ring crimping for securing bolts, eyeleting for securing terminals, and similar features are produced by press-crimping using a crimping jig.

Motors used in the tilt mechanism of a truck cabin.

Parts used in continuously variable transmissions.

Coils assembled with a no-fuse circuit breaker. We can provide bobbin winding, hollow winding, fusing, enamel removal, pre-soldering, and similar processes.
