DUNKES stretch forming presses are engineered to give manufacturers precise, repeatable control when forming sheet metal, extrusions, and brake-formed profiles. Systems are configured around the part\u2014not the other way around\u2014whether that means a sheet press for large, complex panels or a swing-arm (V-press) design optimized for extrusions and formed profiles. Each platform can be adapted to handle all three material types, giving you flexibility as programs evolve.<\/p>

Stretch forming is relied on worldwide where dimensional accuracy, surface quality, and consistency matter most\u2014particularly in aerospace. We understand the demands of aerospace production environments: tight tolerances, traceability, and long-term process stability. Our presses are built to deliver reliable, repeatable results shift after shift, with the control and precision required for critical structural components.<\/p>

DUNKES is committed to supplying hydraulic press solutions that support stable production, reduce rework, and perform predictably over the full life of the equipment.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Designed to grip each end of the sheet stock material. Then it applies the required tension force to stretch the material beyond its yield point and into its plastic region. It maintains the sheet tension while the sheet is wrapped over the Forming Die. This process creates quality parts with no wrinkles, even stress distribution, and minimum spring back. <\/p>\n<\/p>\n

The machine\u2019s structural components are designed using FEA, stress relieved, and accurately machined to provide rigid support of the forming process.<\/p>\n<\/p>\n

The Loading, Unloading, and Forming motions of the press are controlled by a PLC-based CNC control system. An added feature of the control system is the ability to create part forming programs. The programs provides consistent and repeatable forming cycles for quality parts production. The programs can be saved and reloaded for future use. <\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t
