Applications and functions This series testing machine adopts hand control. It is mainly used to do tensile test, compression test, bending test, torsion test, shear test to examine mechanical properties of metal materials, non-metal materials, composite materials and other materials. Features 1.Stable and reliable loading frame Loading frame adopts underneath hydraulic cylinder. Main loading parts use high stiff materials and good connecting to reduce inclination angle of crosshead under load, enable very precise alignment and application of force to specimen. 2. Easy and convenient to install and take off specimen The clamps adopt whole open structure to enable install and take off specimen easity Using of hand control box to control open and close of clamping jig to effectively install and take off specimen 3. Precise measuring and control system Bidirectional load cell is used, high precision, stable, and accurate. High effective and precise servo measuring control system is used to make the machine response as quickly as possible during operation and test and high precise test results(force at break, tensile strength, compression strength, yield point, elongation, etc) are got after test. 4. Extensive applicability A wide range of gripsenables test machines to be used for tests on plastics, elastomers, metals, composites, paper, board, textiles, foams, foodstuffs and components, while the generous test-area depth allows the use of larger fixtures and enables larger components to be tested. 5. Accord with many test method Test method of GB, ISO, JIS, ASTM, DIN, BS, EN, etc can be satisfied. 6. Safe Limit position protection of cylinder Over flow protection of hydraulic system
