ECT-100 Erichsen cupping tester  is mainly used to check the ductility of metal sheet and strip. It conform with ISO 20482:2003 Metallic materials - sheet and strip - Erichsen cupping test standard.  GB 5125-2008 (Method for deep drawing cup testing of non-ferrous metal). Can inspect the ductility deformation performance of test sample and inspect anisotropism of metal sheet.
Erichsen cupping test mean use certain size steel ball or ball shape punch, press a sample that be loaded a 10KN pressure, till the sample appear a penetrate through crack. Check the deep (mm) at this situation, this deep value is called Erichsen cupping test result value.

Features:
1, Adopt advanced new structure, servo motor constant speed loading, constant rate control, microcontroller to control the punching process, can preset the speed.
2, Clamping force is apply by independent hydraulic oil source, can adjust the clamping load, can independent calibrate.   
3, Force measuring change from oild sensor to load cell, encoder to measure the cupping value. Our low friction moving device technology used in the punch moving system, improve the test data repeatability, accuracy and reliability.
4, Test fixture easy to change, sample dismantle and installation convenient.  install the sample, then press a button will automatically clamping. Can input or change test parameter, punching process is PID control, automatically judge the sample cracking and automatically stop.  With watch window, can easy observe sample cracking, for the ultrathin sample can manually stop the test.             
5, Test result is computer display, with peak value memory function, max. punching load, Erichsen cupping value etc.,  can save the test result, curve drawing, test report etc.,  one test finish can automatically back to initial condition.
