Abstract (en)

[origin: WO8903754A1] The present invention briefly refers to a method for controlling the melt temperature of plastic raw material during the manufacture of plastic articles. The desired melt temperature is obtained and/or maintained by changing the amount of mechanical energy supplied to the raw material in the plasticizing section.

Abstract (fr)

L'invention se rapporte à un procédé de régulation de la température de fusion de matière plastique brute pendant la fabrication d'articles en plastique. On obtient et/ou on maintient la température de fusion voulue en changeant la quantité d'énergie mécanique appliquée à la matière brute dans la partie de plastification.
