The main differences between rubber and plastic tensile, compression and bending testing machines lie in their application scope, test items and applicable standards.
Application
Tensile testing machine: Mainly used to test the tensile, compression, bending, shearing, peeling and other mechanical properties of materials. Suitable for testing rubber, plastic, metal and other materials, widely used in scientific research, teaching, quality control and other fields.
Pressure testing machine: mainly used to test the pressure performance of materials, suitable for compression performance testing of rubber, plastic sheets, pipes, special-shaped materials, etc.
Bending tester: specially used to test the bending properties of materials, suitable for testing the bending strength and modulus of plastics, metals and other materials
Test items and applicable standards
Tensile testing machine: can test tensile stress, compression strength, bending strength, tear strength and other mechanical properties. Applicable standards include：GB/T 16491-2022、ASTM 3330、ASTM D903 、 CNS11888 、JIS-K6854 etc.
Pressure testing machine: mainly used for compression performance testing, applicable standards such as GB/T 1041-2008, etc.
Bending testing machine: specially used for bending performance testing, applicable standards such as GB/T 9341-2008, etc.
Structural features and technical parametersTensile testing machine: common hydraulic and electronic types, with high precision, wide speed range, compact structure, etc.
Pressure testing machine: usually electronic type, with high precision and stability
Bending testing machine: the structure may contain special fixtures and measuring devices to ensure accurate bending test results
