Micro-injection: from theory to practice
Micro-injection is a mass production method for plastic micro-components. The phenomena linking the
conditions for implementation on one hand, and the micro-structural and mechanical properties of the
micro-parts on the other, are nevertheless rarely studied. Research was undertaken at the Institute to try
and address this issue. Regarding semi-crystalline polymers, significant quantitative differences in the
morphology of the micro-parts and traditional injected parts can be observed. Without prejudging the differences
regarding their mechanical properties, this outcome allowed us to progress towards the definition
of an objective criterion for the differentiation of micro and macro parts.
