How to Choose a Reliable Tensile Testing Machine


When selecting a tensile testing machine, the first step is to understand what types of tests your company’s products need to undergo. These may include stretching, compression, shear, adhesion, peeling, tearing, and other material-specific tests. Identifying these requirements will help you choose a machine that fits your specific needs.

To ensure you make the right choice, consider the following four key factors:

1. **High Precision**: A reliable tensile testing machine should offer high accuracy in force measurement, typically within ±0.25%, and displacement accuracy as precise as 0.001mm. This ensures consistent and repeatable results, which are essential for quality control and research.

2. **High Intelligence**: The machine should be equipped with smart features such as automatic break detection, automatic return to the starting position, manual control points, unit switching, and language support. It should also have an internal printer, adjustable upper and lower deviation limits, automatic alarm signals, and output capabilities. These functions enhance efficiency and reduce human error during testing.

3. **Powerful Software**: The software should allow for closed-loop control of force, speed, and displacement. This is crucial for conducting low-cycle fatigue tests and material retention tests on materials like rubber. The system should support full data recording, test result storage, and various curve analyses—such as stress-strain, force-displacement, force-time, and deformation-time. It should also be able to store up to 10 sets of measurements for printing or averaging.

4. **Multi-Functionality**: A versatile tensile testing machine can be adapted with different fixtures to perform a wide range of tests, including tension, compression, bending, shearing, tearing, and peeling. This flexibility makes it suitable for multiple applications and future testing needs.

Choosing the right tensile testing machine is not just about buying equipment—it's about investing in accuracy, reliability, and long-term performance. Make sure the machine you select meets all your current and future testing requirements.

Continuous Beam Formwork

Continuous beam is a common term for two or more continuous collinear beams that are supported by columns or other beams without seismic performance requirements. It is not often built in earthquake-prone countries like Greece. On the other hand, it is widely used in areas with little seismic activity. As far as steel bars are concerned, the structure of continuous beams without seismic behavior requirements is much simpler than that of seismic beams.
