Foundry: Introduction to the reasons affecting the quality of agricultural machinery castings

Foundry: Introduction to the reasons affecting the quality of agricultural machinery castings

Foundry: The quality of agricultural machinery castings has a significant impact on the performance of mechanical products. For example, the wear resistance and dimensional stability of equipment castings directly affect the accuracy and service life of machine tools. The size of the impeller, the cavity of the housing and hydraulic parts, the accuracy of the molding line, and the surface roughness of various pumps directly affect the working efficiency, energy consumption, and cavitation development of the pump and hydraulic system.
