The present invention relates to a resilient material lined stator and method of forming. A method of forming a resilient material lined stator can include disposing a resilient material tubewith a profiled helical inner surfaceinto the bore of a body. A cast materialcan be disposed therebetween. The cast materialcan bond to the bodyto form a resilient material lined stator or the bodycan be removed. The cast materialcan include a conduitor conductorextending therethrough. The cast materialcan include a pathwayformed therethrough. The resilient material can be an elastomer.

Controlled thickness resilient material lined stator and method of forming

The present invention relates to an automatic elastomer extrusion apparatus and method. An apparatusfor in-situ extrusion of an elastomeric coatingon a profiled helical surfacecan include a template () forming a gap between the profiled helical surfaceand an adjacent profiled helical surface () of a template () itself to extrude an elastomer therethrough. A tracking mechanismand/or carriagecan allow a template to follow the contours of the profiled helical surface. The apparatus can include means for providing relative movement between the profiled helical surface and the template. The apparatus () can include a cleaning module (), an adhesive application module (), an elastomer deposition module (), and/or a curing module (). Each module can further include a template () and/or a tracking mechanism
