Method for manufacturing tubular body, involves bringing material to be transformed warmly in material-deforming tool and pressing material by mold of material-deforming tool in mold cavity

摘要

The method involves bringing a material (3) to be transformed warmly in a material-deforming tool (1) and pressing the material by a mold (4) of the material-deforming tool in a mold cavity (5) for forming an end piece (9). A tubular central section is extruded after forming the end piece, where fiber-reinforced plastic is utilized as the material. An independent claim is also included for a controlling arm for a chassis of a vehicle.
