摘要： A mandrel for a molding system includes a support structure formed in a generally closed loop shape. The support structure is formed of a plurality of discrete segments coupled together. The number of discrete segments is increasable or reducible to change the overall geometry of the closed loop shape. The mandrel may be part of a molding system that includes a mandrel surface that closely fits about the outer surface of the mandrel body. The mandrel surface is formed of a plurality of discrete toothed segments that form a generally closed loop shape.
