Compensation of Fluctuations in Plastic Viscosity
Thanks to Regulation of the Injection Volume with iQ weight control
The software optimises the injection volume during the ongoing injection moulding process. This regulates fluctuations in plastic viscosity. iQ weight control compares the injection pressure curve of each cycle with a previously defined reference curve and reacts to external influencing factors. The accuracy of the injection moulding process is increased, and the weight of the components remains constant.
The intelligent assistance programme, iQ weight control, regulates every injection process during production. It corrects the injection volume and calculates the switching point of the injection moulding process in the same shot, depending on the plastic viscosity. Fluctuations are compensated for in each shot, thus reducing the scatter of the moulded part weight by up to 85%. You benefit from better process stability, increased part quality and process repeatability.
Fluctuations in the viscosity of plastics are a major challenge when processing recyclates. iQ weight control detects these fluctuations in the raw material and adjusts the injection profile and the changeover point to the current production conditions in the same shot. Recyclates can thus be processed from different sources - with a significantly minimised reject rate and increased productivity.
The simple visualisation when monitoring process-critical parameters in production immediately shows where adjustments are necessary in the injection moulding process. Using automatic calculations of the parameters, the software compares the pressure curves of the injection volume and the reference curve determined by iQ weight control. As a result, the system detects differences and corrects deviations in terms of plastic viscosity quickly and efficiently.

iQ weight control enables a significant advantage in terms of part quality and productivity in a wide range of applications thanks to regulation of the injection volume. In addition to the economic aspect, a key feature of our assistance systems is their ease of use.
Braun, the manufacturer of electric shavers, has reduced weight fluctuations from 0.02 g to 0.003 g with iQ weight control - an 85% improvement in weight consistency.
To ensure consistent part quality, intelligent assistance systems such as iQ weight control do a great job in the high-performance range. Closure production also benefits from this.
