1、 Overview

The rubber tensile testing machine is suitable for measuring the mechanical properties such as tensile, tear, peel, compression, and bending modulus of various materials. This machine is an advanced computer-controlled testing instrument.

The rubber tensile testing machine is a gantry structure, using an imported servo transmission system, imported ball screw transmission, equipped with imported force sensors and automatic elongation tracking and displacement devices. During the experiment, the microcomputer continuously collects signals of force and deformation, and processes the data according to the requirements of the experiment. The PC automatically saves the test data, and the test results are printed out by the printer.

Its characteristics are advanced technology, high degree of automation, and high testing accuracy.
