Cylinder Head Products

The cylinder head produced by our Baohua Company can be made of different materials according to customer requirements. Materials such as 45 #, 40Cr, 30CrMo, 35CrMo, 42CrMo, 18CrNiMo7-6, etc. In addition, Baohua Company has independently developed the double cavity forging process, which can greatly improve the forging efficiency and reduce the blanking weight, and ultimately achieve the goal of cost saving. Forging is carried out on different forging equipment units according to different weights. The weight of forged products can reach 6kg-500kg. Forging needs to be completed through heating, pre forging, forming, trimming and other processes.

The cylinder head is generally cast by high-quality gray cast iron or alloy cast iron, while the gasoline engine used for cars mostly uses aluminum alloy cylinder heads. Aluminum alloy has good thermal conductivity, which is conducive to improving the compression ratio of the engine. Secondly, the casting performance is excellent, which is suitable for casting parts with complex structures. However, attention must be paid to the cooling of the aluminum alloy cylinder head, and the temperature of its bottom plane must be controlled below 300 ℃. Otherwise, overheating of the bottom plane will cause plastic deformation and warping.

The cylinder head is a box shaped part with complex structure. The intake and exhaust valve seat holes, valve guide holes, spark plug mounting holes (gasoline engines) or fuel injector mounting holes are machined on them. The cylinder head is also provided with a water jacket, an air inlet and an exhaust port, and a combustion chamber or a part of the combustion chamber. If the camshaft is installed on the cylinder head, the cylinder head is also provided with a cam bearing hole or a cam bearing seat and its lubricating oil passage.

Cylinder head forgings

The cylinder heads of water-cooled engines have three types of structures: integral, block and single. In a multi cylinder engine, if all cylinders share one cylinder head, the cylinder head is said to be an integral cylinder head; If there is one cover for every two cylinders or one cover for three cylinders, the cylinder head is a block type cylinder head; If each cylinder has one head, it is a single cylinder head. Air cooled engines are all single cylinder heads.
