Claims16
A method for use in producing a stator for a progressing cavity apparatus, the method comprising:
- (a) providing a stator tube electroforming mandrel;
- (b) incorporating the stator tube electroforming mandrel into an electrolytic cell so that a cathode of the electrolytic cell is comprised of the stator tube electroforming mandrel;
- (c) electrodepositing a thickness of a deposited metal onto the stator tube electroforming mandrel as an electroformed deposit;
- (d) removing the stator tube electroforming mandrel from the electrolytic cell;
- and
- (e) separating the stator tube electroforming mandrel from the electroformed deposit, thereby producing a stator tube, wherein the stator tube is comprised of the electroformed deposit.
