DK28 diesel engine accessories products cylinder head body

The manufacture of engine cylinder head body first needs to prepare various raw materials, including casting materials, processing materials and so on. Casting material is an important material, its quality directly determines the strength and durability of the cylinder head and other performance parameters. Common casting materials are iron, aluminum, magnesium and so on. The cylinder head materials of different engines are different, and in order to reduce the brittleness of the material and make the cylinder head have higher strength and hardness, it is usually necessary to improve the material performance by adding some metal elements.

Adding an appropriate amount of impurity metal to the casting material can strengthen the structure of the material, and improve its rigidity, toughness, heat resistance and wear resistance and other physical properties, so that it is not easy to deform under high temperature and high pressure. At the same time, in order to process faster and improve casting efficiency, some high-quality tools and processing equipment should be selected when preparing processing materials.

The casting process of Marine diesel engine parts cylinder head body is divided into sand casting and pressure casting. Sand casting is to pour the metal liquid into the mold in the sand mold, and then wait for the metal to cool and solidified and set, and then knock the sand mold for post-treatment. Pressure casting is the use of liquid metal for high pressure injection molding, cylinder head casting molding efficiency, stable output quality, high product fineness, long life.
