Today, hot embossing and injection molding belong to the established plastic molding processes in microengineering. Based on experimental findings, a variety of microstructures have been replicated so far using the processes. However, with increasing requirements regarding the embossing surface and the simultaneous decrease of the structure size down into the nanorange, increasing know-how is n...

This paper presents the application of injection molding of wedge-shaped plates for lightguiding application. This paper discusses the influence of processing parameters on injection molding. The filling stages of lightguide plate for mold flow simulation (3D, midplane) are analyzed. The numerical simulation of mold filling process is based on the concept of control volume finite element method...

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 state of melt viscosity in injection process is significantly influenced by the setting parameters due to that the shear rate of injection process is higher than other processes. How to determine plastic melt viscosity during injection process is important to understand the influence of setting parameters on the melt viscosity. An apparatus named as pressure sensor bushing (PSB) module that...

High demand for plastic worldwide has resulted in increasing environmental pollution. To make the manufacturing process more environmentally friendly, recycling of waste must be considered. In view this a social enterprise called Me.reka Makerspace aims to use produce recycled products using injection molding. However, molding is complex process. past experienced numerous failures resulting def...

The two objectives of this research are to produce plastic that is environmental friendly whereby the plastic produced can be at least slightly decomposed to smaller substances by the living organisms from marine algae and also to characterize the plastic that have been produced from the marine algae via mechanical and physical testing. In this study, algae which are Red Eucheuma cottonii are t...
