Method and mould for manufacturing a drip-irrigation dispenser (emitter), and this dispenser (emitter)

摘要

The invention relates to a method for manufacturing a drip-irrigation dispenser (emitter) by injection moulding, as well as this dispenser (emitter). The dispenser (emitter) is formed by three annular elements 54, 56, 58 which are moulded onto staged sections of a main core 38 and which are fitted onto each other telescopically at the same time that they are ejected from inside of the mould. The assembly of the various elements of the dispenser (emitter) is therefore carried out at the moment that they are ejected from the mould. Field of application: drip-irrigation devices.
