Fuel cooler
Aluminum heat exchanger with brazing to cool fuel
Cooling risen temperature of fuel due to increase of fuel injection pressure to comply with stricter emission regulations for diesel vehicles.
To prevent thermal damage to fuel system parts.
Parts for electric vehicles, others
Upper cover (For inverter)
Protecting electronic components in the PCU (inverter) in the event of a collision.
Iron plate is used to reduce costs and meets strength required to withstand collisions.
In addition, it has high corrosion resistance and design properties by applying a cationic electrodeposition coating.
It was adopted for the first time in 2022. (NOAH, VOXY)
Reducing cost by manufacturing with an integrated production line through pressing to final process.
Inverter bracket for hybrid vehicles
Bracket with vibration reduction performance, impact absorption performance in the event of a collision, and radio noise suppression function.
Holding PCU (inverter), prevents vibrations occurring in engine and transaxle from being transmitted to the PCU, and having a radio noise suppression function.
It has been adopted since Prius in 2015.
We offer optimal shape and complex bracket shapes with optimal processes.
Engine mount bracket
Metal bracket to prevent engine vibration from transmitting to vehicle body.
First product in our history.
It is assembled on vehicle body in combination with vulcanized rubber to support engines.
We have know-how of pressing with complicated shape, welding, painting, and assembly.
We are also able to offer optimal shapes and conduct various evaluation by using analysis technology.
Cooling water/Oil system pipe
Resin pipe in the cooling system
Resin Pipe achieving weight and cost reduction
It has achieved 25% weight reduction and 50% cost reduction compared with conventional ferrous materials.
By adopting PIT for molding process, it is possible to ensure surface property on the inside of pipes and the stability of the wall thickness.
In addition, its material is PPS and it has excellent heat resistance and hydrolysis resistance.
※PIT(Projectile Injection Technology)
＝Resin bullet assist molding
Stainless pipe in the cooling system
Stainless steel pipe with high strength, high corrosion resistance, and high heat resistance.
For material of pipes, adopting stainless steel with excellent corrosion resistance.
With our various technique of bending, joining, and end forming for pipes, we are able to accommodate even complicated shapes.
Either welding method or brazing method is available for joining process.
Multiple portions can be joined at once because a whole part is heated in brazing process.
Welding is also available.
Responding flexibly to required product shape and production volume.
Oil cooler tube
Pipe to connect the oil cooler and the transmission
50% weight reduction and 10% cost reduction are achieved by using aluminum pipes in place of conventional iron pipe with surface treatment.
It has excellent corrosion resistance by providing a sacrificial layer on outer surface.
In addition, the necessary strength is ensured by brazing the bracket to the pipe.
Whole part is thrown into brazing furnace and multiple portions can be brazed at once.
We accommodate various design in shape according to customers’ needs including bending shapes.
