The double arm tensile testing machine is mainly suitable for the detection of metal and non-metallic materials, such as rubber, plastic, wires and cables, optical fiber cables, safety belts, belt composite materials, plastic profiles, waterproof rolls, steel pipes, copper materials, profiles, spring steel, bearing steel, stainless steel (such as high hardness steel), castings, steel plates, steel strips, non-ferrous metal wire materials in tension, compression, bending, shearing, peeling, tearing Two point extension (with an extensometer) and other tests. This machine adopts an electromechanical integrated design, mainly composed of force sensors, transmitters, microprocessors, load driving mechanisms, computers, and color inkjet printers. It has a wide and accurate loading speed and force measurement range, and has high accuracy and sensitivity in measuring and controlling load and displacement. It can also perform automatic control experiments for constant speed loading and displacement. The floor standing model, styling, and painting fully consider the principles of modern industrial design and ergonomics.

The double arm tensile testing machine adopts a fully digital servo speed control system with high speed accuracy and stable performance. The servo motor is the driving system, the fully digital controller is the control system core, and Windows is the operation interface control and data processing software to achieve screen display of test force, peak test force, transverse beam displacement, test deformation, and test curve. All testing operations can be automatically executed on the computer using the mouse. Good user-friendly design makes testing operations easier. By combining the above technologies, the machine can achieve nearly perfect closed-loop control of parameters such as experimental force and displacement, and can achieve control modes such as constant stress and displacement, and can smoothly switch between various control modes. This machine fully meets the requirements of the national standard GB/T228-2002 "Metallic Materials Room Temperature Tensile Testing Method", and can be tested and data processed in accordance with GB, ISO, JIS, ASTM, DIN, and various user provided standards, with good scalability.

Dongguan Hongjin Testing Instrument Co., Ltd.was founded in June 2007 It is a high-tech manufacturing company that specializes in the design and automatic control of large-scale non-standard testing equipment like simulated environmental testing, material mechanics testing, optical dimension measurement, vibration impact stress testing, new energy physics testing, product sealing testing, and so on! We serve our customers with the utmost passion, adhering to the company concept of "quality first, honesty first, committed to innovation, and sincere service," as well as the quality principle of "striving for excellence."

What are the typical components of a dual arm tensile testing machine?

Load Cell (1)

The weighing sensor converts the tension into a measurable electrical signal. Zwick weighing sensors not only ensure high-quality products, but also are seamlessly compatible with all of our machine components.

Extensometer (2)

An extensometer is a strain measuring device used to measure the strain of a specimen, also known as strain measurement. Almost every standard requires strain measurement for tensile testing, such as ASTM and ISO.

Sample fixture (3)

The sample fixture provides a mechanical connection between the sample and the tensile testing machine. Their function is to transmit the movement of the crosshead to the sample and transmit the test force generated in the sample to the weighing sensor.

Moving the crosshead (4)

The moving crosshead is essentially a crosshead that can be controlled to move up or down. In tensile testing, the crosshead speed of the testing machine is directly related to the strain rate in the specimen.

Electronics (5)

Electronic components control the moving parts of the tensile testing machine. The speed and load rate of the crosshead can be controlled by the microprocessor in the servo controller (motor, feedback device, and controller).

Drive System (6)

The driving system provides different power and frequency levels for the motor of the tensile testing machine, indirectly controlling the motor speed and torque.

Software (7)

Our testing software is a very user-friendly, wizard guided, Windows based solution that allows users to set up testing systems, configure and run tests, and display results.
