Nowadays, with higher and stricter requirements for components and end products in uniformity, geometry, accuracy, and cost-saving, hydraulic straightening presses have been more and more widely used by manufacturers who intend to improve productivity while saving costs. Hydraulic straightening presses are particularly useful for shafts, plates, and large weldments. Machining, heat treatment, and forming can cause these kinds of workpieces to warp or deform. Manufacturers have to remove or reduce such deformation before moving on to the next production steps. Especially for shafts, which are more complicated and have diversified sizes, it is barely possible to automate the straightening process, so a (hydraulic) straightening press is required. Regardless of whether you are bending or straightening large sections of steel alloy I-beams for the railroad industry, high-strength alloys for aerospace parts, or rugged chassis for off-road vehicles, Shuntec has the solution.
For customers from the automotive industry, who require accurate and repeatable straightening processes for precision parts, the Shuntec C-frame presses are the ideal straightening press to choose from. The press provides flexible precision control modes, which are “fixed speed/setting position stop”, “fixed speed/setting load stop”, and “fixed speed/pressing distance stop”. The accuracy ranges from 0.01mm (0.0004 inches). A shuttle bed can also be offered for some special occasions, to offer the repeatable straightening cycle and the ability to automatically straighten.
All gantry and C frame hydraulic straightening presses in Shuntec are built with tough quality standards to ensure years of maintenance-free and reliable operation.
