Abstract

a. Procédé pour la réalisation d'un réflecteur optique, notamment pour projecteur d'automobile. b. Procédé caractérisé en ce que l'on injecte dans un moule une première matière plastique, le volume de cette matière ne correspondant qu'à une partie du volume du moule et on fait fluer cette première matiere plastique sous la forme d'une peau contre les parois de ce moule par injection immédiate d'une seconde matière plastique qui, en repoussant la première matière, se loge entre les deux peaux formées par cette première matière contre les parois du moule.at. Method for producing an optical reflector, in particular for an automobile headlight. b. Process characterized in that a first plastic material is injected into a mold, the volume of this material corresponding only to a part of the volume of the mold and this first plastic material is made to flow in the form of a skin against the molds. walls of this mold by immediate injection of a second plastic material which, by pushing back the first material, is housed between the two skins formed by this first material against the walls of the mold.
