During the demoulding stage of the hot embossing process, the force required to separate a polymer part from the mould should be minimized to avoid the generation of structural defects for the produced micro structures. However, the demoulding force is dependent on a number of process factors, which include the material properties, the demoulding temperature, the polymer pressure history and th...

In this paper we present an analysis on MoLICC, an interaction design language rooted in Semtiontic Engineering that perceives the user-system interaction as a conversation between designer (the system) and user, bringing focus to collaborative systems based on the 3C Model of Collaboration. In our analysis, we present the different aspects of collaboration as defined by the 3C Model of Collabo...

Purpose The purpose of this study is to demonstrate and characterise a soft-tooled micro-injection moulding process through in-line measurements surface metrology using data-intensive approach. Design/methodology/approach A soft tool for demonstrator product that mimics the main features miniature components in medical devices microsystem has been designed fabricated material jetting technique....

The making of ear mould for hearing aids is generally considered to be a safe process. However, there are a few reported cases of complications caused during mould making. We report the case of a man with 69 years age, where the process of making the mould for a hearing aid led to the perforation of the tympanic membrane and pouring of mould material into the middle ear, necessitating surgical ...

This article is focused on the calculation of heat radiation intensity and its optimization on an aluminum mould surface. The inside of the mould is sprinkled with a special powder and its outside is heated by infra heaters located above the mould surface, up to a temperature of 250°C. By this way artificial leathers in the car industry are produced (e. g. the artificial leather on a car dashbo...

the rapid growth in natural gas consumption has increased the need for gas storage, in particular in the form of injection into depleted reservoirs. also, co2 sequestration into the depleted reservoirs has attracted a large attention recently. however, it is important to ensure that the injection pressure is maintained below a certain limit to avoid unsealing the cap rock or reactivation of any...
