Using Vacuum Low-pressure Casting to Found Water Pump Copper Impeller
The vacuum low-pressure casting was used to found water pump copper impeller.In the process of casting,the rapid prototype technology was used to make complex ceramic mould core,and the complex ceramic mould core was used to form the impeller's complex inner chamber structure.The metal mould and special made vacuum low-pressur casting device were used to found Water Pump Copper Impeller.The impellers casting made by this foundry technology have good dimensions precision and surface glabrous degree,can meet the use needs of the water pumps.
