Abstract
A method for molding a plug and a hose or a pipe, wherein the plug is part of a pipe connection and the pipe connection is constructed as a sealing plug-in connection between a connecting piece and the plug. The plug includes an outer part and an inner part connected to each other in one piece and a rear free end of the plug forms an annular gap. The deformation forces acting on expanding jaws of an expanding device during the molding of the plug and the hose or the pipe are directly recorded and the molding of the plug and the hose or the pipe is performed in dependency on these directly recorded deformation forces. As a result, a constant molding degree is achieved in case of plugs and hoses or pipes with varying wall thicknesses.
