This testing machine is mainly used for repeated bending test of metal wire and testing performance an d defect of bearing plastic deformation at the process of bending metal wire repeatedly.You can operate on digital display screen and it shows bending times. It can also process sheet metal bending test after using sheet clamping device. The Cupping testing Machine ( Erichsen Tester) is precise technology testing machine which i s used for sheet metal & strip steel rolled stock etc. It can complete test of plastic deformation for sheet metal & strip steel rolled stock. • By changing different specification clamping jaws that can do a variety of specifications of materials bending test. • Stepless speed test. • Equipment stable performance, compact structure, reliable qua lity.Simple, bending frequency digital display. • Low noise running smoothly, reliable long life, reasonable desi gn, easy maintenance. It conforms to ASTM E 643-78 & GB4156-84 named Testing Machine for MetalCupping test • Mainframe—Iset High performance reduction system- • Dedicated bending fixture—Iset Dedicated blessing fixture—Iset • Measurement and control system-----Iset Frequency Control System-----Iset • Three-phase asynchronous motor—Iset • Photoelectric bending frequency measuring device—Iset
