Valve Cover

The valve cover is a critical component of the automotive engine. We utilize advanced powder metallurgy pressing and forming technology, employing an integrated powder metallurgy molding process to completely eliminate defects such as pores and sand holes that occur during casting. The surface treatment involves resin impregnation followed by blue-white zinc electroplating, ensuring high corrosion resistance and rust prevention, thus completely preventing oil leakage from the source. The integrated design allows for the complex internal oil baffle and reinforcing ribs to be formed in a single process with the main body, reducing welding points, significantly improving structural reliability, and lowering assembly costs. This ensures perfect sealing from the very first product.
