Brief Introduction of Aluminium piston skirt
Forged aluminium piston skirt is the future development direction and goal of engine. For heavy-duty and high-power diesel locomotive engines, in order to meet the needs of high explosive pressure (greater than 20 MPa), forged aluminium piston will gradually become the mainstream of design. Piston is the core part of the engine, its performance directly affects the performance of the engine. At present, the main forming methods of piston are gravity casting, pressure casting, forging and so on. Compared with the casting process, the forged piston can be formed by plastic processing, and the grains can be refined, streamline distribution, internal defects such as voids are more compact after welding. The mechanical properties, thermal conductivity and high pressure resistance of the forged piston are obviously enhanced, which increases the reliability of the piston work.
The production process of Aluminium piston skirt
