The EGR Housing cools the exhaust gas and injects it into the combustion chamber of the engine along with air to reduce emissions. To maximize its efficiency, the product has separate coolant and exhaust gas passages inside. This product is manufactured by the gravity casting method to form water channels using core inside.

The manifold assembly distributes the fuel/air mixture evenly to the cylinder head for the purpose of maintaining the engine's efficiency and performance. It is a one-piece product assembled with sensors and controls to maintain ride comfort and required power during driving. This product is manufactured by the gravity casting method using cores to form a hollow part that allows air to flow inside.

The WTC housing makes up the Water Temperature Control assembly and has a central function of the automotive engine coolant temperature control, which prevents engine overheating and manages transmission oil temperature. This product is produced with an additional process of casting with a core inside for the complex internal conduit configuration, and then removing it again. This is a housing product for a thermostat that assembles SUS pipes are applying the gravity casting method.

The transmission oil pump cover supplies hydraulic oil inside the automatic transmission which requires a precision machining process to maintain the clamping force with the assembled products and prevent hydraulic oil leakage. This product is manufactured by gravity casting method using a core to form a hollow part that allows oil to flow inside.

This product plays a role of a passage to evenly distribute fuels/air mixture through the cylinder head in order to maintain engine efficiency and performance.
