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 computational cost of high-fidelity injection molding simulations has been growing in the past years making it more and challenging to use them for performing analyses such as optimizations or uncertainty quantification. Surrogate modeling offers a cheaper way realize studies gaining attention field simulation. In this work, we propose compare three surrogate techniques along with two desig...

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...

Autodesk Moldflow is a simulation package for plastic injection molding. As part of the solutions for Digital prototyping, it helps CAE analysts and manufacturers optimize the design of plastic parts and injection molds. In general, models of the plastic parts are created at the first stage of product optimization and the major concern is the manufactured quality of the parts. Once the product ...

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...
