In response to the increasing world wide demand for small diameter (i.e., 0.188″ to 0.375″ OD) steel tube for both refrigeration and automotive purposes, Yoder can provide equipment for production of these tubes. Since 1992, complete Yoder Cold-Stretch Reduction Small Diameter W-10 / W-15 Tube Mill Systems have been supplied to Turkey, China (2 lines), South Africa, and the United States. This U.S. line may be the first new mill of its type installed domestically in the last fifteen years.
Yoder has been involved with the pipe producing market for many years. Cutoffs have evolved from rotary disc or tool machines to friction saws to the latest saw technologies. Milling saws provide a fantastic edge finish with minimum burr but tend to have longer cycle times. Formtek works with its licensee Milltech to provide the pipe mill markets the highest quality with the greatest performance. Milltech has developed mill cutoff systems utilizing 2-heads or 4-heads (depending on pipe size) to provide the best combination of end finish and cycle time performance. These machines are designed to handle the heavy strains put on them by the demanding cycles required by our customers.
Yoder M-Series Roll Forming Systems are one of the most popular and copied mill stands in the world. Highlights of these systems include:
Yoder has been in the pipe industries for over sixty years. Pipe is often threaded for a particular application and Milltech has developed two pipe threading systems to handle sizes up to 13-3/8” OD and 20” OD. These machines perform extremely fast cycle rates and when you put them into your threading system – your thread processing costs will certainly decrease!
Milltech and Formtek can now offer you either stand alone machines or complete threading systems, depending on what best fits your budget.
MTL Series
The MTL-340 series will produce 4-1/2” to 13-3/8” (114.3 to 339.7 mm) OD while the MTL-508 series will 10-3/4” to 20” (273.1 to 508.0 mm) OD. The MTL-340 has average cycle rates of 44 pcs/hr while the MTL-508 has average cycle rates of 37 pcs/hr. Different thread types can be produced, please inquire.
Yoder QVW-Series Roll Forming Systems feature:
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 has long been recognized as one of the earlier pioneers in the welded seam tube mill business. Yoder Tube and Pipe Mill Systems include multiple standard tube mills for common product sizes. In addition to the standard machines, Yoder also offers specialized equipment that covers a huge diameter range of metal tubes and pipes; from the 3/16″ (4.76mm) O.D. cold stretch reducing mills to the 28″ OD cage mills. As required by the application for welding the tube or pipe, Yoder can provide mills with high-frequency induction or contact welders, DC & AC Square Wave Welding (ERW), TIG and laser.
For Tube and Pipe manufacturing, Yoder provides a range of solutions to fit the application: complete mills, individual machines, mill accessories, tooling, as well as well as consulting, engineering studies and retrofits to existing installations.
Yoder Tube Coilers are available in two and three basket configurations for recoiling small diameter single wall and double wall tubing, used in fuel lines, refrigeration, and brake line applications.
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.
Yoder is one of the few companies in the roll forming industry that can provide equipment for the heavy gauge and high-strength steel markets. Yoder WH-Series Roll Forming Systems offer increased strength capabilities, decreased changeover time and simplified maintenance compared to the W-Series machines that preceded them. Like the Yoder tradition, the WH-Series machines continue to utilize rugged cast housings made in the United States, machined, assembled and tested at our facility in Cleveland, Ohio.
