Vehicle wheel cast aluminum alloy comprising a style motif, process for obtaining such a press and mold used for the method

摘要

Wheel (1) of aluminum alloy, especially a motor vehicle wheel, comprising at least one unit of style (2) reproduced on at least one face (23) of the wheel (1), characterized in that the motif (2 ) comprises a plurality of parallel successive grooves (21) extending in a substantially circumferential direction relative to the center of the wheel (1) and whose dimensions are of the same order of magnitude as the tolerances so obtained with a molding process to low pressure; performing the wheel (1) and the subject (2) of successive grooves (21) by a single operation of low-pressure molding.
