The quality of the green and the shaping efficiency are affected by the mold structure during the course of powder injection molding (PIM). Based on the numerical simulation, the mathematic model for the optimal design of the gating and runner system in PIM mould is constructed. The method is testified by the Moldflow software and the experiment. From the result, it is suggested that the clamp force and the shape cycle are clearly decreased, the green is densified and the samples’ density error of the green is decreased after the optimal design of the mold structure. Furthermore, the number of trial mold is reduced and the shape efficiency is improved.

The paper finished the design of injection molding by UG MoldWizard module, and realized numerical simulation and analysis of injection process by MoldFlow software. Best gate location was obtained. Fill time was deeply studied. Though the mold designing process, it completed the CAD/CAM/CAE integration of the injection molding, and achieved the optimal design of the mold. NC machining of the mold core was programmed by UG NX software. CAD/CAM/CAE greatly improved the development efficient of the mold.

Solid Conveying

Understanding the solid conveying process is important for the optimal design of micro injection molding machines. To solve problems such as starve feeding and process instability during plastication of polymers, which deteriorate product qualities, studies have been carried out on the conveying process of discrete polymer pellets. The effect of screw axis inclination on the speed of solid conveying is investigated with both simulation and experimental approaches. A discrete element modeling method (DEM) specially designed for simulating polymer particle movements in screw channels, which takes into account the effect of gravity while maintaining the simplicity of calculations, has been developed. The agreements between results of simulations and experiments verify the integrity of the models developed herein. The proposed modeling method is capable of optimizing the design of plasticizers of micro injection molding machines.

Abstract The present work concerns optimal design for the injection molding process of a deflection yoke (coil separator). The optimal design for the injection molding process is developed using design of experiments and finite element analysis. Two design of experiments approaches are applied such as: the design of experiment for mold design and the design of experiments for determination of process parameters. Finite element analyses have been carried out as a design of experiments for mold design: runner system and cooling channel. In order to determine optimal process parameters, experiments have been performed for various process conditions with the design of experiments scheduling.
