Abstract
An injection molding process for fabricating a sliding vane pump with a close tolerance between the rotor assembly and the pump chamber using two semi-circular inserts to hold the rotor assembly while the molten plastic is injected to form the housing. The inserts function to stop the molten plastic from entering the rotor assembly during injection and upon removal to form the inlet and outlet ports of the pump.
