For large machinery and equipment, the choice of brand, manufacturer, model, after-sales service, price, and other issues is very important, so how to choose the right universal testing machine for you? How should we choose in the procurement process?
Here is the content list：
Determine the ASTM or ISO national standards
Outline the calculations required to test the sample
Select the maximum load required to test the material
Determining the maximum speed required for testing
Selecting the required fixtures or fixtures
Determine the deflection meter or extensometer
Consider the functions needed

Each material sold to the public or private sector must be rigorously tested according to national recommendations. The first step is to determine the type of material for which the universal testing machine can test
Outline the calculations required to test the sample and which systems have such capabilities. One of the most important parts of selecting a universal testing machine is choosing the controller to go with it. NANJING T-BOTA SCIETECH INSTRUMENTS & EQUIPMENT can provide correct controller and software which accords to international standard, which ensure customer to get correct testing result.
The type of universal testing machine can be determined based on the maximum load required to perform the test. Once the maximum load is selected, characteristics such as benchtop versus floor standing, double column versus single column, and electromechanical versus hydraulic can be understood. The force capacity ultimately determines the size of the system. NANJING T-BOTA SCIETECH INSTRUMENTS & EQUIPMENT offers several series of load cells to meet the customer's needs.
The operating speed of a material testing system can specify the motors, actuators, and drives required to equip the universal testing machine. This is an important factor to consider for static versus dynamic fatigue testing.
Depending on the type of sample being tested, the fixture purchased may be beneficial or detrimental to the overall results. The fixture is appropriate. The tester should be equipped with the proper fixture. Fixtures should not cause the sample to break at the fixture. When any load is applied, the fixture on the universal tensile tester should be immediately aligned with a line so that the long axis of the specimen coincides with the direction of tension through the centerline of the fixture. For example, cord and wire sample need tensile clamp, pneumatic type or normal type can be ok.
Depending on the type of test you are performing, an extensometer can accurately determine the elongation of the specimen during the test. NANJING T-BOTA SCIETECH INSTRUMENTS & EQUIPMENT offers several types of extensometers.
Consider the functions needed
Consider all the possible applications your universal testing machine will need to perform. While you may only need tensile and compression capabilities today, your material testing needs may expand in the future and you will need torsion, bending, peel, and fatigue testing. By considering all the options you may need for your universal testing machine, you will be able to reduce costs in the long run by purchasing an all-inclusive system.
The most important thing is the brand. The testing machine industry is a relatively mature market. There are many brands, but each has its focus. But when buying and selling, you should also pay attention to whether the tester manufacturer is professional and competent. Can the service keep up, because it is impossible to leave the future use?
