General introduction
Mobile phone Glass screen compression, bending strength tester / Mobile phone 3-points compression testing machine is widely used for compression and bending tests on products such as tablets, mobile phone lenses, and glass. It features a servo motor, ball screw, and original USA load cell, making it an ideal testing device for related manufacturing enterprises, colleges and universities, research institutions, and technical supervision departments. For evaluating the bending resistance and physical-mechanical performance of mobile phone glass screens, as well as similar materials like tablet glass, LCD glass, and tempered glass. It ensures the quality and durability of glass screens by simulating real-world stress scenarios (e.g., accidental drops or pressure) and complying with international and industry standards such as GB, ISO, JIS, ASTM, and DIN.
Equipped with dedicated test control software and clamping devices, it can test the performance of lenses. According to standards, it can automatically determine parameters such as maximum test force (minimum force/average value), breaking force, tensile and compressive strength, elongation, peel strength, and peeling force. The results are accurate, reliable, and highly repeatable. It can also perform data rounding and print mechanical performance indicators such as Fm, Rm, Rp, ReH, ReL, Re, A, Z, E, as well as curves for load-deformation and stress-strain relationships. It comes with specialized fixtures for three-point compression, four-point compression, and bending tests, making it an ideal device for enterprises, regulatory agencies for product inspections, and research and teaching in universities and colleges.

Key Features
Multi-mode testing: It mainly conducts three-point bending and four-point bending tests; with customized fixtures, it can also perform tensile, shear, compression, and puncture tests (e.g., crush test, ROR test, ring-on-ring test for sapphire glass).
Intelligent data analysis: Equipped with a computer control system (Windows OS) and a liquid crystal display, it dynamically shows test curves (force, displacement, deformation) in real time. It automatically calculates key parameters like bending stress, bending strength, bending modulus, and compression strength.
Safety & automation: It has multiple protection mechanisms (overload protection when exceeding 10% of maximum load, electronic limit, mechanical limit) and automatic functions (automatic stop when the sample breaks, automatic return of the test bench after the test, batch test execution).
It is widely used in R&D, production, and quality inspection links of industries related to mobile phone glass:
Testing the bending resistance of mobile phone/LCD screen cover glass to prevent breakage during use.
Evaluating the mechanical performance of special glass materials (e.g., sapphire glass for high-end phones, tempered glass).
Verifying whether glass products meet international standards (e.g., CT 2130-2012 for mobile electronic product screen cover glass, ASTM D6109 for plastic/glass flexural properties).

Standard
ASTM C158 is a standard test method for determining the flexural strength (modulus of rupture, MOR) of glass and glass-ceramics via bending, covering two core methods (A for flat glass, B for rectangular/elliptical cross-sections) with clear specimen, equipment, procedure, and calculation rules. It is critical for glass engineering as flexural strength directly governs structural safety, design optimization, and compliance with industry standardsNational Glass Association.
