Abstract
Described is a method for manufacturing a diaphragm assembly through the use of injection molding. The method can avoid the use of PTFE as a chemically resistant coating. Further, the method can increase overall adherence of a polymer diaphragm to an insert through the use of an interference surface on at least the surface of a head of the insert.
