Dishing and Flanging

JMT is proud to announce their long awaited partnership with a world renowned builder of the utmost quality Dishing and Flanging machines available to modern industry worldwide. JMT is currently one of only a very small contingent of suppliers certified to represent this manufacturer in North America.

In the storage tank, pressure vessel fabrication industries, making the cylinder portion of the completed tank or vessel is by far the easiest part of the project. The equipment required to fabricate these cylinders is usually a fairly common 3 or 4 roll plate rolling machine. A rather simple set or multiple set of tank turning rolls and a welding manipulator or two. Just like that, you have a solid steel cylinder of varying diameters, thickness, and lengths well on your way to a completed tank or pressure vessel right? But how do you form or fabricate the tank/vessel ends known in that industry as the “caps. “or “bottoms” ? These pieces can be somewhat complex, with a specific radius, may or may not have a center hole, may or may not have numerous holes all around it and oh yeah, needs to have a specific flange rolled up its edge so the cap has some way to be connected to the cylinder. These caps or bottoms can range from as small as 36 inches in diameter to well in excess of 300 inches or more and our line up of dishing and flanging machines are up to the task.

Enter, JMT’s new lineup of dishing and flanging machines. The process of creating a tank cap or bottom requires 3 separate pieces of machinery to accomplish the finished piece part. First the flat round steel blank is set on the manipulator so the blank can be positioned underneath the main ram of the dishing press. The pressing sequence then begins with the main press making its first impression on the flat blank. The manipulator then repositions the blank in a spherical motion all the way around the circumference of the steel blank, until it arrives at its initial starting position. The manipulator then repositions the blank in reference to the main ram end and begins to make another circular pass, progressively moving up the wall of the dished piece part until the cap or bottom has been pressed to customer specifications. This entire sequence occurs automatically between the manipulator and the main press via a simple programming control panel which has been programmed by the operator. Now that you have a dished tank end cap or bottom how do you attach it to the cylinder of the tank that is being fabricated? The next process that is required to complete a tank end cap is called the “flanging process”. This flanging process is accomplished utilizing a machine called curiously enough, a flanging press. JMT has you covered there as well. As all three pieces of equipment originate from the same world renowned manufacturer, all three machines work in near perfect harmony. The flanging press takes the completed dished cap or bottom and rolls a specific flange dimension per customer requirements. This operation is accomplished with a press specifically designed to do this work which is equipped with a set of dedicated rolls which can be positioned in relationship to each other to achieve the specific flange dimensions.

As we have demonstrated in every other category of machinery we sell, JMT only partners with the best equipment manufactures in the world. Our new flanging and dishing machines are literally constructed to last decades. With all the newest stress analysis, three dimensional state of stress to mass considerations, and decades of experience engineering and building these machines, quality and durability is inherent from the base up. These ultra-heavy duty machines are all electron beam welded construction and chemical atmospheric quenching process to relieve all stress in the major casting and fabricated components. All primary internal components are supplied from the best producers worldwide.
