Abstract

Se describe una investigación experimental realizada para estudiar el comportamiento en condiciones reales de insertos
para cavidades fabricados con dos aleaciones de aluminio diferentes. Se fabricaron 1000 piezas (probetas para ensayo de
plásticos) de polipropileno, empleando un molde de diseño normalizado con insertos para la cavidad correspondiente,
fabricados con cada una de las aleaciones a ensayar. Cada 250 piezas producidas, tanto las cavidades como la pieza
elaborada fueron medidas en zonas previamente seleccionadas y estos resultados se emplearon para caracterizar el
comportamiento de las aleaciones ensayadas. Las condiciones de presión y temperatura del proceso de inyección se
seleccionaron atendiendo a los requerimientos industriales que corresponden al plástico utilizado.

Abstract:
The behaviour of cavities in molds for plastic injection, manufactured with two different aluminium alloys under real
conditions is described by experimental investigation. 1000 pieces (probes for testing mechanical properties of plastics) were
produced from polypropylene, using a normalized designed mold with specially manufactured cavities and the two tested
alloys. For the produced pieces, the dimension (width) of the cavities and the elaborated pieces were measured in previously
selected areas, these results were used to characterize the behaviour of the tested alloys. The conditions of pressure and
temperature for the injection process were selected according to the industrial requirements for the plastic used in the
investigation.


Key words: Mold, cavity, aluminium, experiment.
