Plastics is one of the world’s largest and fastest growing industries, ranked as one of the few multi-billion dollar industries. Due to the vast improvements in polymers and production processes, plastics are now amongst the world’s most widely used materials, with the world consumption of polymers surpassing steel in volume and weight. Injection molding represents approximately 32% (by weight)...

Abstract In this paper, injection molding is used as a method of plastic molding, which in the molten state injected into closed mold cavity by compression, and material fills then cured cooling to maintain shape mold. The basic structural form parameters mold’s parting surface, winding system, system are determined flow analysis. CAE analysis move filling computer, casting system’s design sche...

In this study, an adaptive optimization method based on artificial neural network model is proposed to optimize the injection molding process. The optimization process aims at minimizing the warpage of the injection molding parts in which process parameters are design variables. Moldflow Plastic Insight software is used to analyze the warpage of the injection molding parts. The mold temperature...

Injection molding is classified as one of the most flexible and economical manufacturing processes with high volume of plastic molded parts. Causes of variations in the process are related to the vast number of factors acting during a regular production run, which directly impacts the quality of final products. A common quality trouble in finished products is the presence of warpage. Thus, this...

In this paper, a numerical analysis of in-cavity residual stress formation in the thin-walled parts of injection-moulded parts is presented by considering the residual stresses produced during the post-filling stage. Injection moulding of shallow thin-walled parts with a thickness of 0.7 mm was performed using lignocellulosic polymer composites (PP + 50 wt% wood), and the parts have been system...

Injection molding is the most common manufacturing process for production of high volume commercial parts. However, injection molding is characterized by extremely complex process dynamics and material properties, which make it difficult to understand and predict the product quality and can lead to numerous unacceptable quality defects. There are many solutions to these problems – Moldflow is r...

The quality of injection molded products is influenced by several factors: the geometry product, polymer used, mold, technological parameters processing and molding machine itself. For this reason, modelling process computer justified widely used in industry. Modelling, however, complicated complex flow dynamic thermal processes during molding, changes material structure polymer. Various filler...

Product quality for plastic injection molding process is highly related with the settings for its process parameters. Additionally, the product quality is not simply based on a single quality index, but multiple interrelated quality indices. To find the settings for the process parameters such that the multiple quality indices can be simultaneously optimized is becoming a research issue and ...
