“…This shows that the hot embossing temperature is the most significant factor affecting the transcription rate of the embossed parts. This result was in good agreement with results of other investigations [17,18]. Figure 7 shows Fresnel lenses fabricated by the conventional hot embossing molding process parameters and optimal hot embossing molding process parameters [24].…”

“…In the Taguchi method, the design parameters of the system to be studied are known as the process control factors or design variables, which mainly affect the output of the objective function. Factors affecting the transcription rate of the embossed parts in the hot embossing molding include embossing temperature, embossing pressure, demolding temperature, pressure holding time and cooling rate [18][19][20][21]. In the present study, four parameters (hot embossing temperature, hot embossing pressure, demolding temperature and pressure holding time) were used as control factors.…”

This paper proposed a method for fabricating a microstructured hot embossing tool with excellent replication fidelity using rapid tooling technology. The optimal hot embossing molding process parameters of Fresnel lens was also investigated using the Taguchi design method. The experimental results revealed that the most influential factor affecting the microstructures of Fresnel lens is the hot embossing temperature. The optimal hot embossing molding process parameters are hot embossing pressure of 83 kgf/cm 2 , hot embossing temperature of 155°C hot embossing time of 6 min and demolding temperature of 55°C. The depth transcription rate of the embossed part can be enhanced about 7.8% using the optimal hot embossing molding process parameters.

“…These researchers also observed that the coated stainless steel micro-moulds exhibited better replication performance compared with bare stainless steel micromoulds in terms of the quality of the polymeric micro-fluidic devices fabricated. Shuhuai et al [40] studied the principal factors affecting the final replication fidelity of the hot-embossing process of glassy polymers for pattern replication. The relationship between the process condition and final quality was thoroughly and systematically investigated.…”

Micro-metal injection moulding process technology is one of the key technologies to satisfy the increasing demands for smaller parts associated to miniaturisation and fictionalisation in different application fields. The process combines the shape-making capability of polymer by hot embossing with sintering technology to produce complex, high density metal parts with outstanding properties. The present work focussed on elaboration and characterisation of feedstock based on 316L stainless steel powders for micropowder embossing process. In this paper, the rheological specifications of the binder and the feedstock were observed by means of capillary rheometry. Thermogravimetric analysis was carried out on feedstock in order to understand decomposition behaviour of the binder components. The effects of sintering temperature on the dimensional stability, and particularly hardness of sintered components, were investigated. The results show that the feedstock can be used for the manufacturing of the micro-fluidic die mould cavities with a low roughness, proper dimensions and good shape retention.
