Abstract
A method for automatically balancing the volumetric filling of cavities, especially of multiple injection molding dies, which is characterized by detecting the temperature profile in the cavities and averaging the same for all cavities.
Claims3
A method for automatically balancing the volumetric filling of a plurality of individual cavities of multiple injection molds comprising:
- providing a plurality of individual cavities;
- positioning a temperature sensor in each of the individual cavities at a location along the filling path of each of the individual cavities;
- providing an individual hot runner for each of the individual cavities for feeding a melt to each of the individual cavities;
- sensing when the melt in each of the individual cavities contacts the temperature sensor to determine the time taken to fill each of the individual cavities;
- identifying a temporal offset for filling each of the individual cavities;
- and
- controlling the temperature of the individual hot runner for each of the individual cavities to balance the volumetric filling of each of the individual cavities without the temporal offset.
