Cavity Pressure Behaviour in Micro Injection Moulding
Process monitoring of micro injection moulding (µIM) is of crusial importance to analyse the effect of different parameter settings on the process and to assess its quality. Quality factors related to cavity pressure can provide useful information directly connected with the dyanmics of the process as well as with the filling of the cavity by the polymer melt.
In this paper, two parameters derived from cavity pressure over time (i.e. pressure work). The influence of four µIM parameters (melt temperature, mould temperature, injection speed, aand packing pressure) on the two pressure-related outputs has been investigated by moulding a micro fluidic component on three different polymers (PP, ABS, PC) using the design of experiment approach.
Similar trends such as the effects of a higher injection speed in decreasing the pressure work and of a lower temperature in decreasing pressure rate have been found for all three materials.
