This chair shape extrusion is a one-piece extrusion profile extruded from our
100MN extrusion press. It is extruded for the spectator stand seats of the Stadium
for the London 2012 Olympic Games. Its size is exactly the size of a real chair, about
800mm (31.496”) high and 508mm (20”) wide. With this giant press, it is possible to make a chair in one whole piece, without further welding or fabricating, due to its large outlet opening and large extrusion billet.

      The 100MN extrusion press is designed to make large section aluminum extrusion profiles, with longer length up to 30 meters, wider width up to 914.4mm (36”). One
piece extrusion profile has the following merits:

1.It can save further welding and joining work: In actual application of
    aluminum extrusion profiles, the parts are often required to be welded together to
   make a functional structure or parts. With larger and wider extrusion section, the
   welding process can be substantially reduced or saved, and some time the
   welding cost itself will be more expensive than the extrusion parts.

2.With whole piece extrusion, the extruded part will be more solid and stronger
    than welded parts. Arc welding seam may crack or leak but extruded part will
   not have such problem. It will remain intact and sound through out its service life.

3.Cost efficient: aluminum extrusion profile of large section and size will be more
   economic than welded parts of smaller size. The extrusion die is only one time
   investment and it will extrude as much as needed without further money input.

4.With high extrusion pressure of 100MN from this giant press, the extruded
   aluminum parts will be more compact in its inner micro structure, grain size will be
   more even and mechanical strength will be more consistent in its entire length. It will
    contribute to longer and stable condition of the extrusion products in its whole
   service life. Products made from such extrusion parts will be more durable in its
   application, tougher in structure and more reliable in its usage.

5.Matched with 30 meters long aging furnace, 18 meters high vertical
    quenching furnace and 2000T stretcher, our 100MN extrusion press line can make
   solution heat treatment to heat-treatable alloys and stress relieving treatment, to
    bring 2xxx, 6xxx and 7xxx alloys into T6511 tempers, which can guarantee the
   strength, hardness and machinability of the extrusion products.
