Adjustment process between the levels of materials universal testing machines

Universal testing machine has the multifunctional application characteristics of tensile testing machine and impact test, and is favored by many customers. Plastic processing companies also use universal testing machine to test, which is convenient for the stability of material performance, easy to operate and low price. The following is a detailed introduction to the plastic universal testing machine:

The universal testing machine for plastic materials includes one or more vertically loaded columns, a fixed horizontal base is installed on the columns, and a movable horizontal cross head (cross beam) is also on the top. In today's rubber tensile testing machines, ball screws are usually used to fix the movable cross head. The bearing level and measurement load of the frame for the size of the universal test machine/A dynamometer of tension is used to represent it together. The dynamometer is attached to a movable cross head driven by a servo motor or hydraulic device. The force magnitude can be measured by a series of dynamometers with fixtures orPCThe machine displays the results. Many hydraulic universal testing machines have interchangeable dynamometers and can therefore match the different materials tested. Static tests are carried out using standard electronic universal testing machines, usually with a loading speed range of0.001~20 in./min(1in.=2.54cm). Dynamic or cyclic tests such as crack growth and fatigue tests are usually performed using a hydraulic servo system universal test machine, which takes longer time and lower loads.

The universal testing machine 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, a universal testing machine can be used to test the materials to determine whether the materials are suitable for certain specific processing applications or terminal applications. Universal testing machines can also be used for product quality control to ensure consistency between batches of product quality.
