Method of manufacture of an automobile structure

摘要

The present invention provides a method of manufacture of a plurality of different automobile structures comprising the steps of forming in a die a plurality of identical castings 10 each having at least one socket open in two directions perpendicular to each other; forming a first length of metallic extrusion 12 of a first chosen cross-section; cutting the first length of metallic extrusion into a first plurality of side rails for an automobile each with the same first length; cutting the metallic extrusion into a second plurality of side rails for an automobile each with the same second length different to the first length; fixing the metallic rails of the first plurality in sockets of a first plurality of castings to form a first type of automobile structure; and fixing the metallic rails of the second plurality in sockets of a second plurality of castings to form a second type of automobile structure.
