With the gradual increase of environmental protection, low energy consumption, low emissions and low pollution have become the goals of innovative design of mechanical products. In order to improve the efficiency of the engine and reduce emissions, the design of the cylinder block tends to be integrated, making its structure more complex, and the requirements for the casting are also higher and higher. The new generation cylinder block integrates the structure of water channel, oil airway and gear chamber, and has higher requirements for core assembly and sand core exhaust in the process of casting production. Thanks to our Sand 3D Printing technology, it really helps a lot to make sure the new generation cylinder head and engine block can meet the processing needs.
