Application of Moldflow and Taguchi technique in improving the productivity of injection moulded energy meter base

Abstract

In injection moulding process, the productivity is largely dependent on the cycle time and its optimisation plays a vital role. Productivity improvement in injection moulding is possible by undertaking scientific moulding using the modern process improvement and statistical techniques. This paper describes the improvement in the productivity of injection moulded polycarbonate energy meter base wherein Moldflow software is used to predict the injection pressure, filling time, clamping force, etc. and the design of experiments is carried out to know the impact of various parameters on sink mark, cycle time and overall quality indexes. The experimentation is done using the predicted values obtained from Moldflow analysis and an orthogonal array is employed for optimising injection time followed by pack time and cooling time. Significant improvements are achieved in reducing the cycle time from 51.5 seconds to 42.0 seconds using the systematic optimised processing parameters and thus increasing productivity.

Optimization of gating system for the inverter shell injection mold based on Moldflow

“…Traditional multi-cavity injection mold production adjusts the flow balance of the gating system through repeated mold testing and repair. With the development and application of computer-aided engineering (CAE) technology, more and more enterprises are adopting injection mold flow analysis technology in plastic mold design to reduce the number of mold testing and speed up product development [4][5][6][7][8]. Based on the Moldflow software, the melt flow balance of the multi-cavity injection mold of the inverter shell is optimized in this paper.…”
