At Toledo Metal Spinning Company we provide custom cone and cylinder fabrication services for customers in a variety of industries including aerospace, agricultural, automotive, building, HVAC, industrial, and manufacturing. We utilize state of the art equipment and the latest manufacturing techniques to meet the highest quality standards.
Cylinder products are produced from a variety of materials, including, but not limited to 1100-O, 3003-O, and 6061-O aluminum, carbon steels 1008-1020, CDA 655 copper, 655 and 718 inconel, and stainless steel series 304, 304 DDQ, 316, 410, and 430.
These materials possess similar properties such as excellent formability, weldability, and strong corrosion resistance. Cylinders can be furnished with custom features including ribbed, custom formed ends, fittings, side holes, and weld flanged options. Forms are created by rolling flat sheets into a round shape, then sealing with a seam weld produced with Jetline TIG welding equipment. Once the metal cylinder is welded, the planishing operation also realigns the molecular structure of the metal to its original state. Our processing yields accurate dimensions, with smooth, strong weld seams.
Size capabilities for cone and cylinder parts are up to 72 in. in length, diameters from 5.5 to 48 in, and thicknesses from 0.030 to .134 in. The tightest tolerances of ±0.030 in are met for parts up to 1 ft in length, with higher tolerances for larger parts. Turnaround times are 2 to 4 weeks, and all parts and processes meet ISO standards as well as our own internal standards for excellence. Value added additional services include secondary forming, welding, metal finishing, engineering support, stamping, embossing, extruding, and, of course, spinning.
There are cut out, edge, profile and welding options available to customize the cylinder for a specific metal fabrication application. Toledo Metal Spinning Company forms and welds high quality sheet metal cylinders to work with other TMS products. Double flanged cylinders are used as non-welded spacers to extend the height of the deep drawn cups and hoppers. When welded construction is preferred, either a plain or single flange cylinder can be TIG welded to either the conical or flat cylinder ends. Using the cylinders in conjunction with our stock metal spun hoppers, deep drawn cups and stainless steel lids will permit a rapid development of a vessel that can be used for several applications mentioned below. For more information about our custom cone and cylinder fabrications or our other available services and products please see the table below or contact us directly.

We can roll up to 6’ in length with up to a 4’ diameter. The thickess can range from .032” thick to .250” thick with materials like cold rolled steel, hot rolled steel, various stainless steels, and aluminum. Copper, brass, and Inconel are also available to roll.
Once the parts are rolled in the Davi roller, we take them over to the tabbing station to tab each end of the cylinder. The tabs are welded to the ends of the cylinder to prevent “blow through” on the cylinder ends. The seam welder will initiate the weld on the tab outside of the main cylinder and continue seam welding throughout the length of the cylinder and onto the exit tab.
Longitudinal Seam Welding
In our large roll and seam weld cell, we have a state of the art Davi roller. The large longitudinal seam weld cell can roll a minimum of .032” thick up to .250” thick by 6′ in length and 5′ in diameter.
Once the seam welding is complete, the cylinder is taken over to the planishing machine to flatten the weld to near flush with the cylinder. Then, the cylinder goes to the cutoff machine to remove the tabs. Voilà! The cylinder has nice and even ends.
At this point, the cylinder could be finished or it could go to the flanging process. We are able to make a single flanged cylinder or a double flanged cylinder. The customer can choose what flange radius they would like. The standard choices available are 1/4”, 3/8”,1/2”, 5/8”, or 3/4”, the radius depends on the material type and thickness. Typically, a radius of at least three times metal thickness is acceptable.
The machine capacity will have a bearing on what the final dimensions of the rolled and welded cylinder will have. This is determined based on the material type, thickness, length, and diameter of the part to be formed. The different material types that can be used on the small and large longitudinal weld cells include but not limited to the following:
|Material Types – Ferrous Metals (Contain Iron)|
|Cold Rolled Steel||304|
|Hot Rolled Steel||304L|
|Inconel 600 Series|
|Inconel 700 Series|
|Material Types – Non-Ferrous Metals|
Lean Manufacturing ; One Piece Flow Technology
Instead of batching parts between each machine, one part is fabricated at a time so that when the part comes out of the cell, it is complete and ready to ship or go to the next cell or department. This method of manufacturing reduces the overall time that it takes to make a completed part.
