“…Although this process is similar to other polymer processing me thods [17][18][19], it requires separate studies due to its specificity. Despite the fact that the origins of thermoforming go back to the 1870s and its practical aspects have been thoroughly examined, the process is still the subject of numerous research studies [20][21][22][23][24][25][26][27][28][29][30][31][32] and publications for manufacturers [33][34][35]. In this paper, a thermoforming process for producing polystyrene sheet by vacuum forming and vacuum assisted drape forming with and without pre-blow is investigated.…”

The paper describes a utility function -based method for optimization of a thermoforming process for producing finished parts made of polystyrene sheet by vacuum forming and vacuum assisted drape forming with and without pre-blow. Not only does the proposed method enable determination of optimum thermoforming conditions, it also provides information about interactions between these conditions as well as about their impact on the properties of finished parts and polymer heating time, a factor which affects efficiency of this process. The determined optimum thermoforming conditions significantly differ for thermoforming without pre-blow and thermoforming with pre-blow, which results from different ways of forming individual regions of polystyrene sheet during both processes. The employed method enables determination several optimum criteria, the number of which can be extended as desired, which is significant for practical applications of machines and devices.

“…Meneghetti et al [13] investigated the thermal properties of clay/polymer nanocomposites and suggested that adding nano-reinforcing particles would improve the properties of the nanocomposite compared to the composite. Mohan et al [14] have addressed the thermoforming of clay/polypropylene nanocomposites by infrared heating. The purpose of this study was to investigate the effect of adding nanoclay to polypropylene sheets during an infrared-assisted thermoforming process.…”

Experimental analysis of the warm stamping of metal/thermoplastic polymer nanocomposite laminates

The effects of matrix type, temperature, and weight percentage of nanoreinforcement on maximum drawing force and drawing depth have been studied in warm stamping of reinforced metal/nanocomposite laminates.The laminates were composed of two thermoplastic polymers of glass fibersreinforced polypropylene and polyvinyl chloride, two reinforcements of nanoclay and multi-walled carbon nanotubes as the core layer, and aluminum 1050-O as the skin layer. Change of the matrix type from polyvinyl chloride to polypropylene increased the maximum drawing force and decreased the drawing depth. Besides, the drawing depth in most samples was decreased by increasing the weight percentage of the nano reinforcement. Increase of the temperature led to increasing the drawing depth and decreasing the maximum drawing force. Temperature had the greatest effect on the output parameters, especially the drawing depth.
