A method of filling the cavity of a tool used for production of a molded part from a melt, especially the cavity of an injection molding machine, wherein the melt is introduced into the cavity under pressure and is subjected to a dwell pressure towards the end or at the end of its flow path. The tool wall temperature is determined at the end of the flow path of the melt and the switching point for switching to the dwell pressure is determined from the increase of the tool wall temperature.

Method of filling the cavity of a tool

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.

Method for automatically balancing the volumetric filling of cavities

A method for regulating the contraction of molded parts in a cavity in a mold of an injection molding machine after completing the filling process of the cavity with molten mass. According to the method, the temperature of the mold is regulated, whereby the temperature and/or the internal pressure in the cavity is monitored and adapted to a reference curve by performing temperature equalization of the mold from the end of the filling phase or from a maximum pressure in the cavity until the end of the injection cycle.

Method for regulating the contraction of molded parts

A method for the automatic identification of sensor sensitivity, according to which resistance of a specific magnitude is allocated to the sensor. The resistance is used to allocate the sensor to a specific sensor group with a predetermined sensitivity range.

Method for the automatic identification of sensor sensitivity

A method for controlling process parameters to achieve constant process conditions, including studying the actual data and reference data independent of time and applying them one on top of the other so that, in the case of optimum match, a 45&#xb0; straight line is achieved or, in the case of non-match, one tries to achieve a 45&#xb0; straight line by modifying the process parameters.
