Final Report - SONOPLAST (New Process and Machinery for Microparts Moulding based on Ultrasound excitation)

Project ID: 222378
Funded under: FP7-SME


This is the final report of the SONOPLAST project which introduces the first ultrasound injection moulding machine exclusively designed for the replication of microparts. The report shows that based on results, it was feasible to think of a compact moulding machine, as the clamping force can be provided by small electric motors. Another important advantage to consider involves eliminating the plastification unit.

Along with the reduction of the sprue volume, those characteristics represent an important cost advantage in terms of raw material and power consumption. The ultrasound transducer gives more energetic efficiency to the process than the electrical heater bands used in conventional injection moulding. Finally, the shorter cycle time exposures the raw material to a significant less risk of plastic degradation, reducing the waste. Images, graphs and charts are also included in the report.
