The glass four-point static pressure testing machine is suitable for four-point static pressure test of various mobile phone glass, computer display, TV screen, tempered glass, glasses glass, plexiglass and special glass. It is widely used in the inspection and analysis of materials in small hardware, building materials, aerospace, machinery manufacturing, wire and cable, rubber and plastics, shock absorbers, textiles, home appliances, etc. It is a research institute, college, industrial and mining enterprise, technical supervision, commodity inspection. Ideal test equipment for arbitration and other departments.
The characteristics of the glass four-point static pressure testing machine: the whole process of data acquisition is not divided into files. The imported servo motor and the self-developed synchronous belt reduction system drive the ball screw to make the whole machine up and down. The balance and stability are greatly extended. Machine life and efficiency; connected to the computer to achieve full computer control and print standard test report, about 100kg of weight completely change the traditional material testing machine machine is bulky, complex operation and other shortcomings. According to the function, it can be divided into digital display and microcomputer control. The digital display is controlled by a single-chip computer or a microcomputer, and the operation is simple and convenient; the microcomputer control is very powerful, and the whole test process is controlled by a computer without manual intervention, and multi-language printing can also be realized.

Test parameters: maximum tensile stress, tensile strength, compressive stress, compressive strength, tensile strength, yield strength, elongation, shear stress, shear strength, tensile stress, constant stress, elongation, stress, tear strength, arbitrary point, arbitrary value Elongation pull-out force Adhesion and peak calculation value Pressure test Adhesion force Peel force test Average peel strength Bend test Bending strength Pull-out force Puncture force test Elastic modulus (Young's modulus) Indentation hardness Non-proportional yield strength Non-proportional elongation

This diameter of this series glass bead is two or three times bigger than regular beads. The surface part beyond paints is higher than regular beads; hence the reflectivity of road marking has been increased, especially in rainy, foggy areas.
The diameter is 850-1400mm (20-14mesh) with ≥80% of roundness. The special coating on the surface of glass bead can improve the adhesion between paint and glass beads, thus the longevity can be increased.

The glass bead can be produced based on the standard of countries or areas, such as EN1423/1424, AASHTO M247, BS6088, JIS R3301 and KS L2521 etc.
