The glass four-point bending testing machine is suitable for testing and analyzing static physical and mechanical properties of mobile phone glass, tablet computer glass, liquid crystal glass and other materials such as three-point bending, four-point bending, compression and tensile tests. According to the customer's product requirements, we can carry out tests and provide data according to international standards such as GB, DIN, ISO, JIS and ASTM (such as JC/T 676-1997 Bending Test Method for Glass Materials, BS EN 1288-3-2000 Building Glass. Determination of Bending Strength of Glass). The glass four-point bending testing machine uses computer-controlled windows operating system to dynamically display the test data curve, and can automatically calculate the parameters such as force, deformation, bending stress, bending strength, bending modulus, compressive strength and compressive force. Test curves and data results can be dynamically displayed and arbitrarily set on the computer, and the curve operation is more simple and easy. All electronic display monitoring such as curve editing, superposition, separation, scaling and printing can be carried out anytime and anywhere. Glass four-point bending testing machine is mainly used in mobile phone, tablet computer manufacturers, colleges and universities, scientific research units, quality inspection centers, quality inspection departments of enterprises, laboratories, etc. It is used for testing the physical and mechanical properties and technological properties of metal and nonmetal materials, rubber and plastic materials, and is favored by users.
