5. Incorporate both side and vertical supports to prevent unwanted bends.

Adequate support requires both side and vertical roller-supports, as designed by the manufacturer of the plate-rolling machine. Once employed, plate rolling becomes a one-man job instead of two. This frees up valuable manpower that can be re-routed to other jobs.

When rolling a cylinder, once the inside diameter is more than 200 times greater than the thickness of the material, the weight of the material becomes sufficient to bend the cylinder as it exits the top roll and gets further away from the machine. Without proper support, unwanted radii result.

1. Purchasing a machine with both side and vertical roller supports easily solves this problem.Some manufacturers attempt to skimp on this ancillary equipment by resorting to "makeshift" support such as a forklift or overhead crane. However, this shortcut ties up the use of equipment that can best be utilized elsewhere. Because it cannot adequately support the material, unforeseen bends can still appear.
2. Between diminishing factory orders and increasing labor and energy costs, companies that use plate metal in their fabricating processes are finding their profit margins increasingly pinched. Yet, manufacturers must still invest in new production equipment -- whether to replace obsolete equipment or to take advantage of new business opportunities -- in order to remain competitive.

Manufacturers must make careful assessments when evaluating the addition of new plate-rolling equipment. Debt capital is still available to purchase new machinery, but paying back the loan will not yield a satisfactory return on investment unless the equipment adds value to the production. Unfortunately, many buyers end up purchasing equipment that lacks the capability and flexibility to meet production volumes and tolerances, simply because they don't understand all available options and considerations. In an effort to help manufacturers optimize plate rolling operations, 5 key considerations are offered in order to choose a proper plate bending machine.

1. Factor in the properties of the material to be rolled.

Even though drawings call for a plate to be rolled down to the same dimensions, a tougher material will require a much higher-rated rolling machine. In absence of such considerations, defects will result and the manufacturer will end up with excessive scrap.
