METHOD FOR FILLING AT LEAST ONE CAVITY

摘要

The invention relates to a method for filling at least one cavity of a tool for producing a preform from a melted mass, especially a cavity of a tool in an injection moulding machine, the melted mass being introduced into the cavity under pressure from a plurality of nozzles. According to the inventive method, a sensor (6a,8a) is associated with at least one nozzle, said sensor determining the flow of melted mass in the cavity, and the filling process through the nozzles is automatically co-ordinated on the basis of the signals of the sensor.
