摘要
The object of the invention is a process for manufacturing a product comprising at least one zone of polymeric material, in particular thermoplastic; from a dry knitted preform. The dry preform is made in three dimensions, by weft knitting of a continuous piece corresponding to the shape of the finished product to be obtained. The preform is then consolidated by heating under pressure in a mold and then cooled. The method according to the invention is particularly advantageous because it makes it possible to obtain parts made of polymeric materials of controlled thickness; the finished products have no connection and do not require any assembly of different parts. The method does not cause any loss or fall of material. The method according to the invention is not accompanied by any emission of volatile elements that are toxic at room temperature.
