Abstract (en)
[origin: WO2008148826A1] The invention relates to a shaping method wherein a material (10) of a workpiece (12, 30) is shaped using at least one mold (14, 44, 48, 50, 142). In order to allow a wider variety of shapes while enhancing quality, a lubricant (18) is used between the material (10) and the at least one mold (14, 44, 48, 50, 142), the viscosity of said lubricant being variable by applying or varying a field (56).
