Components that are assembled in automobile engine cylinders by assembling the water temperature controller and are gradually plasticized in aluminum casting products.
In the case of plastic water temperature regulators now mass-produced, they are injected at high temperature (290 ° C) with engineering plastics (HTN),
high pressure hose for extracting cooling water is assembled. There is a parting line of injection mold in high pressure hose assembly part, and It is applied to complete vehicle by processing after injection.
