BENITEZ-RANGEL, J.P.; MORALES-HERNANDEZ, L.A. e TREJO-HERNANDEZ, M.. Improvement Performance of the Filling Step in Injection Mold through Vibration. Ing. invest. y tecnol. [online]. 2012, vol.13, n.4, pp.403-410. ISSN 2594-0732.
This paper shows the flow improvement in the filling step of the polymer injection process due to the polymer excitation though vibration. This process can be split up into three main steps: filling, pocking and cooling. Several mechanical and aesthetic properties of the finished product can be changed in the filling step. The objective of this investigation is to demonstrate the improvement in the filling mold under vibration without adding chemical products. To reach this result, an experimental mold was designed and manufactured in which a vibration device was coupled; it was possible to demonstrate the vibration advantage through this process. Moreover, a heuristic methodology was proposed for the experiment which shows an improvement in the filling process with frequencies close to 3 Hz.
