Background. The object of research is the technology of manufacturing parts on injection molding machines. The subject of the study is the influence of the parameters of the material injection process on the quality of the shape and surface of the product. The purpose of the work is the optimization of technological parameters for the elimination of rejects of products without conducting experimental works.
Materials and methods. Computer modeling in CAE-systems based on the finite element method was applied. The optimization is performed using a sequential search simplex strategy.
Results. A computer model of a mold assembly using a three-dimensional finite element is developed. The modes of operation of the automatic thermoplastic were determined, which ensured the absence of defective products.
Conclusions. The developed technique makes it possible to improve the quality of products on existing molds with design flaws without carrying out experimental studies. It is also possible to predict the level of product quality with the high level of reliability when designing molds.
