Mechanical testing equipment covers equipment used for bonding, compression, drop (impact), tensile, vibration and fatigue testing. The increasing importance of quality control and assurance in production has led to an increasing demand for mechanical testing equipment that has adopted quality control procedures at all production levels in many industrial markets. Mechanical testing for quality control has two main purposes: product durability analysis and product safety assurance. Understanding the strength and durability of the product is beneficial to both end users and suppliers. Mechanical testing helps improve product quality because it enables manufacturers to test material properties before and after the final assembly stage. Due to the diversity of mechanical testing equipment, materials and structures of various sizes can be tested for quality. Mechanical testing methods include user interface options, display options, other output options and environmental parameters.

- ? ASTM defines adhesion as a kind of interfacial force, which may be caused by valence, interlocking, or both to fix two surfaces together. Adhesion is one of the most important characteristics of film systems.
? Compression tests can be performed on materials for multiple purposes. Depending on the type of material, compressive properties may be quite different from tensile properties.
? Tests that characterize material properties under constant strain or stress conditions fall into the category of creep and stress relaxation. These tests can provide important information about the properties of materials or components under long-term conditions.
? Drop mechanical testing is also called impact testing; it is usually performed as part of the hardware qualification or design process. The information obtained during the impact test can improve the survivability of the product and verify its performance in service.
? Ductility can also be called bending or bending test. Ductility refers to the ability to undergo plastic deformation during stretching or bending before breaking.
? Fatigue tester can also be called dynamic tester. The fatigue tester measures the fatigue strength or destructive resistance of materials under controlled cyclic deformation conditions.
? The two most commonly used methods in impact testing are Charpy and Izod. The impact test measures the energy absorbed by the sample before it ruptures. This energy consists of several energy contributions, including the energy absorbed by the impact machine through vibration after the initial contact with the sample and the energy loss of the pendulum during hammering (in the pendulum impact During the test) the total energy consumed by the impact of the sample and the deformation and fracture of the sample.
? Shear strength is defined as the maximum stress that a material can withstand before shear failure. The calculation of shear strength depends on the test method.
? Tensile mechanical testing is the most common type of material and product testing. From quality control to research and development, most laboratories basically need to characterize and report tensile test performance.
? The vibration test system is used to evaluate the design purpose of products and packaging, and to simulate the vibration effect of product transportation. - Technical indicators
