Mechanical properties of micro-injection moulded components
Macromolecular Symposia, 2002Micro-injection moulded specimens and components were investigated using instrumented indentation testing and tensile testing. Conventional nano indentation testing, from which hardness and modulus can be obtained, is useful for the characterization of thermoplastics and filled thermoplastics. The difficulties of indentation measurements on LCPs can be

Biopolymers Processing Experimentation by Micro Injection Moulding
AIP Conference Proceedings, 2011Most of Micro‐Mechanical product new applications are disposable polymer parts. The increasing of environmental concerns and the unsustainability of petrochemical resources are going to promote the employment of biopolymers in the near future. A new approach to experimentation in Micro‐Injection Moulding (MIM) is presented in this paper, where a ...

A New Approach For The Validation Of Filling Simulations In Micro Injection Moulding
AIP Conference Proceedings, 2007In manufacturing polymer micro products, numerical simulations are used with the same purposes as in conventional injection moulding, mainly the optimization of micro components design, the optimization of process parameters and the decrease of production costs. Dedicated simulations softwares fail to correctly describe the melt flow in microstructures,

Selected Problems of Micro Injection Moulding of Microelements
2007Tests results of filling micro-channels by synthetic polymers were displayed. Special test mould was applied, having ability of being heated or cooled. The material tested was polyethylene. Test results have been shown on Fig. 3 to 5. Filling tests were carried out depending on injected material temperature, injection pressure and mould temperature ...

A Novel Setup for Cavity Pressure and Temperature Measurements in Micro-Injection Moulding
Proceedings of the 4M/ICOMM2015 Conference, 2015In injection moulding, continuous monitoring of temperature and pressure parameters in the mould cavity is very important for process control and optimization. In the micro injection moulding process, however, it is more difficult to measure the cavity pressure and temperature due to the extremely small sizes involved.

Improving the accuracy of micro injection moulding process simulations [PDF]
, 2013 Process simulations in micro injection moulding aim at the optimization and support of the design of the mould, mould inserts, the plastic product, and the process. Nevertheless, dedicated software packages for micro injection moulding are not available. They are developed for macro plastic parts and are therefore limited in the capability of modelling
