Aluminum suitable for die casting process represents a specialized category of metallurgical material known as die cast aluminum, which encompasses various aluminum alloy compositions engineered specifically for high-pressure injection molding applications. This material class incorporates an integrated system of sophisticated technical components including core withdrawal mechanisms, precision cooling circuits, and auxiliary support infrastructure designed to manage the complex thermal and mechanical stresses inherent in industrial production.

The main function of the front and back end covers is to install bearings, fix the rotor, to ensure that the rotor and the stator coaxial, the general structure of the front cover is the bearing hole step + housing positioning step + housing fixing screw through the hole, part of the motor fixed flange, the general structure of the back end cover is the bearing hole step + housing fixing screw through the hole + blade cover fixed thread hole.
