The testing machine uses AC servo motor as the power source, adopts advanced chip integration technology, professional design of data acquisition and amplification and control system, realizes the full digital adjustment of control and display in the process of amplification of test force and deformation and A / D conversion. This machine can test and analyze the mechanical properties of various metals, nonmetal and composite materials. It is widely used in aerospace, petrochemical, machinery manufacturing, wire, cable, textile, fiber, plastic, rubber, ceramics, food, pharmaceutical packaging, aluminum plastic pipe, plastic doors and windows, geotextile, film, wood, paper, metal materials and manufacturing industry. According to GB, JIS. ASTM, DIN, ISO and other standards can automatically calculate the maximum test force value, breaking force value, yield strength, upper and lower yield strength, tensile strength, compressive strength, elongation at break, tensile modulus, bending modulus of elasticity, shear test data.strength testing machine
