Abstract: A method and apparatus for manufacture of duckbill valves (1) in which the opposed lips of the valve (1) are split by applying a high fluid pressure inside the valve (1). This pressure causes the valve to balloon and burst. Preferably, the valve (1) is supported over all of its outer surface except the end (6) to be split by a die (5, 10). The system is particularly suited to duckbill valves made of thermoplastic elastomer.
