Influence of Ultramelt process is dependent on material’s MFI, polymer type and processing conditions used. ¡Highest increases in flow have been achieved with low MFI PP grade -3.0 ¡Variability in moulding weight at this time due to manual process control. ¡Probe position within melt chamber has effect on degree of improvement ¡Time Ultrasonics is applied before injection has an effect on results. Initial Injection Moulding Trial Injection Moulding Trials were undertaken to ascertain the effect of: Probe efficiency, operating window for a range of plastics. Initial trials from October achieved 15% increase in flow length By modifying interface between ultrasonic probe and polymer melt, improvement in Flow length increased by 130%. Trials carried out with low MFI PP grades, Moplen HP400K, and processing temperature 220°C Using 80% amplitude from start of moulding cycle - Futher Injection Moulding Case Study Trial Click here to see further details of CASE STUDY 1 Click here to see further details of CASE STUDY 2
