Why does the mesh of automobile oil control valve choose etching processing

Automobile oil control valve is a device that controls the intake valve of the engine to transport engine oil, also called OCV valve. OCV is a low-pressure oil control valve when the variable valve reset timing drives the intake valve of the engine. This device is relatively complex and has a relatively high degree of precision processing, and the products need to undergo strict inspection. At present, OCV control valves with variable valve timing system (VVT) are adopted on mazda 6, Mazda 3 and Mazda Wagon.

There is a precise mesh on the precise OCV valve, that is, the automotive OCV valve mesh. The thickness of this mesh is all below 2MM, and the traditional laser processing can't meet its requirements. At the same time, the characteristics of the material can't be well preserved by laser processing and burning, but the performance of the material can be guaranteed by etching. The fineness of the etched automotive OCV valve mesh can be traced back to the thumb size, and the thickness of 1mm can also meet the processing requirements of etching the automotive OCV valve mesh. The design scheme of automobile OCV can be adjusted at will without high cost by etching, and the etched surface of automobile OCV valve net is smooth and delicate, which can meet its precision requirements when installed in the device.
