Compensation for fluctuations of plastic viscosity

The intelligent assistance program, iQ weight control, adjusts each injection process during production. It detects and monitors the injection volume and calculates the switchover point of the injection molding process in the same shot, based on the plastic viscosity. Fluctuations are compensated for in each shot. This reduces deviations of the molded part weight by up to 85%. Your benefit is better process stability, increased part quality and process repeatability.

Fluctuations in the viscosity of plastics are a major challenge when processing recyclates and bioplastics. iQ weight control detects these fluctuations in the raw material and adjusts the injection profile and switchover point to current production conditions in the same shot. Recyclates and bioplastics from different sources can be processed - with a significantly minimized reject rate and increased productivity.

The simple visualization when monitoring process-critical parameters immediately shows where adjustments are necessary in the injection molding process. By automatic calculations of the parameters, the software compares the pressure curves of the injection volume and the reference curve determined by iQ weight control. The system can detect differences and corrects deviations of the plastic viscosity quickly and efficiently.
