How to adjust the universal test machine at different levels
Nowadays, more and more plastic processing companies are purchasing so-called universal testing machine "universal" testing machine, and use it to conduct tensile, bending, compression and shear tests to evaluate the performance of materials, develop and research the application and quality control. Developed electronics improves the performance of these devices, making them easier to operate and less expensive.
The universal testing machine (UTM) stretches, bends, compresses or pulls the splines of plastic material through adjustments at different speed levels. This is an ordinary equipment in plastic mixing laboratories. During the preparation of compound mixing, UTM testing materials can be used to determine whether the material is suitable for certain specific processing applications or terminal applications. UTM can also be used for product quality control to ensure consistency between batches of product quality.
The UTM test machine includes one or more vertically loaded columns, a fixed horizontal base is installed on the columns, and a movable horizontal cross head (cross beam) on the top. In today's UTM testing machines, ball screws are usually on the columns to fix the movable cross head. The size of the UTM is characterized by a frame bearing level and a dynamometer measuring load/tension force. The dynamometer is attached to a movable cross head driven by an electric motor or hydraulic device. The series of dynamometers with fixtures measure the magnitude of force, and the results can be displayed through a digital display or PC. Many UTMs have interchangeable dynamometers and therefore can match the different materials tested. Static tests are carried out using standard electronic universal testing machines, and the usual loading speed range is 0.001~20 in./min (1in.=2.54cm). Dynamic or cyclic tests such as crack growth and fatigue tests are usually performed using a hydraulic servo system UTM test machine, which is longer and has a lower load.
