Yoder Strut Cable Tray Roll Forming Systems

Yoder Strut Cable Tray Roll Forming Systems

Strut framing channels are used in construction for installation of electrical and mechanical supports as well as utilities and air handling duct to name a few. They are used as a common solution for general industrial framing needs. Due to the versatility of applications and uses, there is a range of strut sizes, material thickness, hole patterns and profile features that may be required. Over the years, Yoder has developed robust Strut Cable Tray Roll Forming Systems for producing strut framing channels that support regional manufacturers as well as the high production OEM producers. The combination strut tooling design that Yoder has perfected enables customers to have a single installation that covers the entire product range with only partial tooling set changeover when switching products. This tooling design helps customers to produce channels in smaller production quantities with faster changeover and less setup scrap so they do not need to maintain large inventories of odd strut sizes in case of an order.

Yoder Universal Cage Forming System

Yoder Universal Cage Forming System

The Yoder Universal Cage Forming System, originated and patented by Yoder, is based on sound mathematics and unique concepts. This method becomes more desirable and essential as the ratio of the pipe outside diameter to wall thickness (i.e., D/t ratio) exceeds 40:1, and up to 100:1 range. More conventional forming methods roll material in discrete steps or passes and employ brute force. The Yoder Cage System forms the strip continuously with smooth transitions and minimum effort. Hence, the material is actually guided through the forming mill with uniform but infinitesimal change of shape in each small increment of pipe travel.

The buckling of strip edges in light wall pipe has been a shortcoming of the conventional pipe mill. This is problem is even more evident now that higher yield strength materials are allowing pipe producers to decrease the wall thicknesses (and pipe weight) further, thus increasing the D/t ratio even more.
