How to choose a universal testing machine that suits oneself?

We have identified an issue

So, let's solve the problem!


Firstly, both hydraulic universal testing machines and electronic universal testing machines belong to material mechanics testing instruments, but they have their own characteristics in structural design, performance, and application scope. Users can decide whether to choose electronic universal testing machines or hydraulic universal testing machines based on the specific usage environment of their industry.

1、 In terms of application scope
Electronic universal testing machine is widely used for testing tensile performance indicators of various metal, non-metal and composite materials, such as wood, plastic profiles, wires and cables, paper, film, rubber, medicine, food packaging materials, fabrics, etc. The digital display electronic universal testing machine is suitable for users who only need force values, tensile strength, compressive strength and other related data. If complex parameters are required, microcomputer controlled electronic universal testing machine is a better choice.
In terms of cost-effectiveness, electronic universal testing machines below 30T have more advantages. The hydraulic universal testing machine is mainly used for testing the mechanical properties such as tension, compression, and bending of metal, non-metal materials, parts, and components. Hydraulic universal testing machine is an ideal testing equipment for industrial and mining enterprises, building materials, quality inspection centers, water conservancy and hydropower, bridge engineering, research institutes, and mechanical testing laboratories in colleges and universities. The electro-hydraulic servo universal testing machine is suitable for laboratories with high requirements for steel and building material testing. Compared with electronic universal testing machines, electro-hydraulic servo universal testing machines with a capacity of over 30T have a price advantage.
2、 In terms of structural characteristics
There are two main forms of electronic universal testing machines: synchronous belts and reducers; Electronic universal testing machines all use load sensors for force measurement.
Hydraulic universal testing machines mainly use high-pressure hydraulic sources as power sources, while electro-hydraulic servo universal testing machines use servo valves or proportional valves as control components for control. Some domestic manufacturers have also adopted high-precision load sensors for force measurement.
3、 In terms of performance
The electronic universal testing machine does not require an oil source, making it cleaner and easier to use and maintain; Its testing speed range can be adjusted, with testing speeds ranging from 0.001mm/min to 1000mm/min and speed ratios up to one million times. The testing stroke can be customized as needed, making it more flexible; High force measurement accuracy, some can even reach 0.2%; Small in size, light in weight, spacious, and convenient to add corresponding devices for various material mechanics tests, truly achieving multi-purpose use of one machine. At present, the electronic universal testing machines produced by mainstream testing machine manufacturers in China can achieve the so-called three loop control of load control, strain control, and displacement control.
Hydraulic universal testing machine, limited by the flow rate of the oil source, has a lower testing speed. Manual hydraulic universal testing machine, easy to operate and inexpensive, but with low control accuracy; Compared with electronic universal testing machines, the performance of electro-hydraulic servo universal testing machines is not inferior in terms of speed and control accuracy.
