Injection molding process is one of the most important methods of forming in the plastics manufacturing industry. Shrinkage and out of roundness are phenomenons that affect the final product quality. In this study, the effect of the thickness of cylindrical parts from polypropylene material on shrinkage and out of roundness has been investigated. For this purpose, injection molding process is s...

Abstract This paper investigates the dependence of functional life additively manufactured plastic insert moulds on occurring shear stresses and temperatures during injection moulding process. As a first step, dedicated is designed that allows for experimentally simulating different rates thermal loads injected polymer in single shot, allowing to assess their effect lifetime insert. Then, numer...

Enjeksiyon kalıplama, plastik ürünler için yüksek verimlilik sebebiyle tercih edilmektedir. sonrasında en önemli unsurlardan birisi de parçanın soğutulmasıdır. Soğutma işlemi, toplam kalıplama süresinin kısmını oluşturmaktadır. Genellikle enjeksiyon kalıplarında soğutma işlemi kalıp üzerine radyal ve eksenel yönde açılan deliklerden sıvısı dolaştırılması ile yapılır fakat soğumanın istenilen dü...

Analytical orientation models like the Folgar Tucker (FT) model are widely applied to predict of suspended non-spherical particles. The accuracy these depends on empirical parameters. In this work, we assess how well analytical can suspensions not only consisting fibers but also an additional second particle type in shape disks, which varied size and filling fraction. We mainly focus FT model, ...

This study aims to develop a simulation-based research evaluate the influence of primary operational conditions on efficiency compression molding in processing thermoplastic parts mold design with no air venting. Moldflow Insight has been used simulate process assess quality range semi-crystalline and amorphous products, performance said mold. Simulation results were obtained by varying surface...

The main objective of this paper is to predict the warpage of a circular injection molded part based on different processing parameters. The selected part is used as spacers in automotive, transmission, and industrial power generation industries. The second goal is facilitating the setup of injection molding machine without (any) need for trial and error and reducing the setup time. To meet the...

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...
