“…The water assisted injection moulding process can also enable greater freedom of design, material savings, weight production, and cost savings in tooling and press capacity requirements. 2 Typical applications include large sheetlike structural parts with a built-in water channel network. Table 1 lists the advantages and limitations of the water assisted injection moulding process.…”

This report investigates the filling phenomena of the water assisted injection moulding process by using a flow visualisation technique. Experiments were carried out on an 80-tonne injectionmoulding machine equipped with a laboratory-developed water injection unit. The material used was semi-crystalline polypropylene. A flow visualisation mould was specially designed and made for this study. A high-speed video camera was used to record the mould filling phenomena of rectangular cavities with three-channel geometry and layouts: a flat plate, a plate with two zones of different depths and a plate with symmetric ribs. The interaction between the assisting water and the polymer melt during moulding was observed, and insight into the water penetration behaviour was summarised.

In recent years, a new and promising polymer processing technology known as water‐assisted injection molding (WAIM) has attracted attention not only for academic reasons but also for its industrial applications. WAIM technology provides a new way to fabricate hollow or other complicated products due to its faster cycling time and light weight. This paper aims to give an overview of the basic principles and applications of WAIM as well as the current research status in academia. The origin and development of WAIM technology are first described and then, their advantages and applications are given. This review focuses on the experimental trends of WAIM such as computer simulation, the effect of processing parameters on the WAIM samples, and the morphology as well as related WAIM–molded composites and polymer blends' work.

“…The profile of the deposited layer on this structure is analysed with a scanning electron microscope. Related investigations to the growth shape of the coating without substrate bias were done by Michaeli et al [2] To characterise the influence of the substrate bias on the molecular structure of the layer, FTIR spectroscopy is used. By adapting FTIR to the coating reactor the molecular composition of the layer system can be monitored in situ during the deposition process.…”

For the development of diffusion and insulation barriers for thin film solar cells on unpolished steel with a rough surface as substrate, investigations of the shape of deposited SiOx layers in dependence on an applied substrate biasing are carried out. Si‐wafers with a well‐defined surface structure in the range of micrometre are used as ‘model’ substrate. As a result, the deposition in the indentations of this surface is much higher in the case of a biased substrate. To determine the influence of the bias on the molecular structure, first investigations of the deposited layer without an applied bias are performed with in situ Fourier Transform InfraRed (FTIR) spectroscopy. Hence the molecular composition of the films is monitored during the deposition. In these spectra the Berreman effect occurs and is analysed.
