Fast Optimization of Plastic Warping Deformation Based on Secondary Development Technology of AMI

Through the combination of orthogonal test method and AMI software, the designing injection molding simulation test can quickly optimize injection molding process parameters which affecting the plastic warping deformation. The orthogonal test scheme and test result analysis are very complex. The development of plastic warping deformation rapidly optimizing software was put forward based on AMI secondary development technology and VB. NET. Considering the factors of mold temperature, melt temperature, injection rate, packing pressure, packing time and cooling time on the influence of warping deformation, designing orthogonal test used L25 (56) orthogonal table. The software automatically created orthogonal test scheme, starting solution analysis, reading the results of warping deformation. The test results data of deviation, range, influence law and influence contribution were analyzed. And the optimal process parameters combination, the maximum of warping deformation under the optimal process parameters combination and the test results were given. Application of the software greatly enhances the optimization efficiency of plastic warping deformation defect.
