METHOD AND METHOD FOR PRODUCING A PREFORM AND AEROSOL FLASK, AEROSOL PREFORM AND AEROSOL FLAKE

摘要

The invention relates to a method for producing a preform comprising the following steps: - providing a matrix (25) of a mold (20) defining a cavity (26), the matrix (25) defining a conduit (40) ) conveying material (15) opening into the cavity (26) through an injection orifice (41); - Arrangement of a spindle (30) in the cavity (26), one end (50) of the spindle (30) being arranged opposite the injection orifice (41); injection into the mold (20) of a first dose of fluidized material (15); - removal of the spindle (30) and injection of a second dose of material (15) fluidized; - final advanced pin (30) in the cavity (26) to bring the end (50) of the pin (30) of the injection port (41); - At least partial solidification of the fluidized material (15) and extraction of the preform from the cavity (26).
