YOU IL Precision Co., Ltd. manufactures cylinder heads and custom-made precision machining products that are assembled into horizontal engines.
The cylinder head is a precision module that is assembled into a engine and plays a role in reducing the amount of heat generated inside the combustion chamber when the engine is operating.
Depending on the cooling performance of this product, it may have a direct impact on engine durability. In addition, we are also manufacturing electronic equipment, exterior and control hydraulic systems for the defense industry (K55, K9, K21, K2, etc.), and control, hydraulic systems and fixtures for the aviation industry (KUH, T-50, KSLV).
