MIM turbo charging blade Technical Field The utility model relates to the technical field of turbocharging blades, in particular to an MIM turbocharging blade. Background MIM turbocharger blades play a vital role in enhancing engine performance as a key component in a turbocharger system. The turbine is driven to rotate by the energy of exhaust gas discharged by the engine, so that the air compressor is driven to compress air, the air inflow of the engine is increased, the combustion efficiency is improved, and the power and torque output of the engine are improved. MIM (metal powder injection molding) technology enables the turbocharger vane to be manufactured in complex and precise shapes, meeting the stringent requirements of high performance engines. In practice, MIM turbocharger blades typically work in conjunction with the following structures: 1. The turbine shell plays roles of protecting turbine blades, guiding exhaust gas to flow and connecting the turbine with an engine exhaust system, and has good high temperature resistance and sealing performance; 2. The compressor impeller is connected with the turbine blades through a connecting shaft and driven by the turbine to rotate at a high speed so as to compress air, and the design of the compressor impeller directly influences the supercharging effect; 3. The bearing system supports the rotating shafts of the turbine and the compressor, ensures stable rotation and low friction, and bears radial and axial loads caused by high-speed rotation; 4.
