In vertical anodising the extrusions are jigged on a horizontal table and are
then raised to a vertical position for transfer through the line. The profiles
are held at one end only, from clamps that never enter the solution, and the
profiles hang from these clamps during processing. The equipment for vertical
anodising lines is more complicated than that for a conventional line, and much
higher and more expensive buildings are required. However such lines have
enormous production capacity. The process sequence in vertical anodising lines is
similar to that in horizontal lines, and all the normal processes can be carried
out vertically. Vertical anodising is very common in Japan, but in Europe and
North America the profiles are essentially jigged horizontally.
