Mask tensile testing machine

The mask tensile testing machine is suitable for testing equipment of non-woven fabrics, industrial masks, medical masks, ordinary masks, N95 masks, medical protective clothing and goggles, etc.It can be used for a variety of tests such as puncture, tensile strength, tensile, peeling, shearing, etc., and can meet standards and industry standards such as GB, ISO, JIS, ASTM, DIN, JG, JT, YB, QB, YD, YY, QC, SY, SL, BB, HG, etc.The testing machine has a powerful CNC display system and microcomputer control processing system. The LCD CNC can also set the required parameters, curves, displacements, and force values. The required parameters can be dynamically displayed on the LCD digital display. The whole process of data collection is not divided into stages. Imported servo motors and Taiwanese industrial machine reducers are used to drive the ball screws to move the entire machine table up and down. The balanced and stable features greatly extend the service life and efficiency of the testing machine. It can be connected to a computer to achieve full computer control and print standard test reports.
