Production
machinery from Atlanta Grotnes uses one, or all of the three methods:
expanding, shrinking and roll forming. Each process produces a
particular end product, and the process which would be used to
produce your product will be determined by your individual needs.

Through the process of expanding intricate contours and sharp profiles
are easily formed Beads, threads, flanges, bosses, flutes or practically
any contour can be achieved. |

|
This procedure is the opposite of expanding. The metal is formed
or sized by compression to a small diameter. This increases the
part's strength by cold-working the metal. It is well suited for
forming tapers, spherical sections, inward beads, offsets and contours.

 |
|
This is a continuous process for forming straight sided cylinders
or rings into shapes of essentially uniform cross sections. During
the process only bending takes place, and the thickness of the metal
is not changed except for a slight thinning at the bend radii. |
| |
|
|
This is a combination of the three major processes. A part may be
expanded and then revolved as a roll moves in to form a groove or
reduced profile. This combination has the advantage of lowering
the tonnage requirements for forming due to the rolling process
and holding tolerance inherent with the expanding process. |
