A testing machine, broadly speaking, is an instrument that verifies the quality or performance of a product or material according to design requirements before it is put into use. From the definition, it can be seen that any instrument used to verify quality or performance can be called a testing machine. A testing machine is a precision testing instrument that measures the mechanical properties, process performance, internal defects, and dynamic unbalance of rotating components of metal materials, non-metal materials, physical properties of mechanical parts, engineering structures, etc. under various conditions and environments.

Tensile testing machineThere are mainly two types of tension measurement and recording devices: mechanical instrument type and sensor type. The mechanical instrument type tension measuring device mainly relies on the reaction force during the stretching process, which drives the pointer on the instrument panel to rotate and indicate the tension value through mechanical transmission devices such as springs and weights, and uses traditional recorders to record the force value time curve. Mechanical instrument typeTensile testing machineThe price is cheap, but its performance cannot meet the requirements of rubber tensile testing. It can only handle tensile values separately and cannot record subtle changes in tensile values, and effectively link tensile values with sample gauge length. A tensile testing machine equipped with an appropriate precision tension sensor can record the tension value at each moment and process and calculate it through relevant programs to meet the requirements of rubber tensile testing.

In the process of global industrial development, testing machines are an inevitable result of the development of industrial civilization. Essentially, testing machine products are instruments used to verify the quality, performance, and design requirements of certain products before they leave the factory. Typical examples include cantilever beamsimpact testing machine、Electronic tensile testing machineThe Mooney viscosity tester and various measuring instruments also belong to this category. While domestic industrial civilization continues to advance, the technological development of testing machines has also achieved remarkable results.
Computer tensile testing machineMainly used for mechanical performance testing in industries such as metal wire, metal foil, plastic film, wire and cable, adhesive, artificial board, wire and cable, waterproof materials, etc. through stretching, compression, bending, shearing, tearing, peeling, cycling, and other methods. Widely used for material inspection and analysis in industries such as factories, mines, quality supervision, aerospace, machinery manufacturing, wires and cables, rubber and plastics, textiles, construction materials, home appliances, etc.

The design of the main unit and auxiliary equipment of the computer bending test machine has the characteristics of beautiful appearance, easy operation, stable and reliable performance. The computer control system controls the servo motor to rotate through a DC speed regulation system, and then decelerates through a reduction system. The high-precision screw pair drives the moving crossbeam to rise and fall, completing mechanical performance tests such as tensile testing of the sample. This series of products has low noise, high efficiency, and a very wide speed regulation range and crossbeam movement distance. Paired with a wide variety of auxiliary equipment, it has a very broad application prospect in metal and non-metal mechanical performance testing. This machine is suitable for various experimental fields such as quality supervision, teaching and research, aerospace, steel metallurgy, automotive, rubber and plastic, weaving materials, etc.
