Predicting flow-induced stress during injection/compression molding

Wei Cao, Qian Zhang, Yanhui Qi, Guixiang Lu, and Changyu Shen
11 March 2016
A new approach, which combines the eXtended Pom-Pom finite element model and an arbitrary Lagrangian-Eulerian technique, is used to simulate stress levels at different points in a molded part.

Rajkumar Subbiah, Mohini Sain, Sanjay K. Nayak, and Jimi Tjong
11 January 2016
Treated sisal fiber-based materials exhibit permeability, resin flow direction, and tensile strength changes compared with untreated samples.

Angle analysis for the evaluation of in-plane anisotropic properties

Claudio Di Fratta
16 December 2015
A new approach, based on angle measurements in simple unidirectional tests, reduces the time, samples, and costs required for determination of material parameters such as textile permeability.

Foam injection molding with nitrogen and carbon dioxide as co-blowing agents

Xiaofei Sun, Hrishikesh Kharbas, and Lih-Sheng Turng
26 November 2015
A novel process combines gas-laden pellets and microcellular injection molding to produce thermoplastic polyurethane foams with low density, uniform cell structure, and high durability.

A novel foaming method for fabricating microcellular injection-molded parts

Lih-Sheng Turng and Jun Peng
6 November 2015
Water vapor represents a new kind of physical blowing agent for the fabrication of foamed-polycarbonate parts with a smooth surface finish.

The skin-core structure of injection-molded parts

Sudheer Bandla and Jay Hanan
3 November 2015
A highly oriented skin layer caused by flow-induced stresses from injection molding was visualized and quantified by x-ray nanotomography.

Core-material penetration in multi-cavity co-injection molding

Chao-Tsai Huang and Jackie Yang
14 October 2015
A high core-material ratio and slow injection speed allow for good penetration, but leading behavior during the runner-filling stage can result in unsatisfactory material distribution in the molded parts.
