Materials Testing Machine FAQ Guide

A material testing system is an essential tool for material testing, and it has been used to specify the suitability of materials for a variety of applications – for example, construction or aircraft construction, machinery, or packaging. Full-scale or small-scale models of proposed machines or structures can be tested. Alternatively, researchers can build mathematical models that use known material properties and behavior to predict the ability of the structure. Below is a complete guide to materials testing systems:

1. What is a material testing machine?

The material testing machine, also known as the material testing system, is a precise test for measuring the mechanical properties, process properties, internal defects of metal materials, non-metallic materials, mechanical components, engineering structures, etc. under various conditions and environments, as well as checking the dynamic imbalance of rotating parts. instrument.

In the process of researching and exploring new materials, new processes, new technologies, and new structures, material testing machines are indispensable and important testing instruments. It is mainly used for testing and analysis of static properties such as tensile, compression, bending, shearing, peeling, tearing, holding the load, relaxation, and reciprocation of metals and non-metals (including composite materials).

2. Why are material testing machines important in the industry?

In order to ensure the quality and safety of materials, material testing has become an indispensable link in almost all industries. This is critical, especially in the construction and car manufacturing sectors, because it can hurt people if something is done wrong.

Therefore, the need for proper material testing becomes indispensable to protect the people who will use manufactured products. In most products, testing is done at the end of the production process. However, rather than testing the entire product, it is a good practice to test individual parts of the manufactured product.

A material testing machine is a tool that can solve this problem. Every part can be tested during the manufacturing process, which can completely reduce the loss of errors. In fact, more and more factories are choosing material testing machines to improve the safety of production.

4. How does the material testing machine work?

The material testing machine/texture analyzer has a load cell on its arm – a highly accurate strain gauge that can measure forces of up to 750kg. The arm moves up and down under the control of Exponent Connect software, which can be programmed to move at a selected speed and to a selected distance, or the instrument can operate as a pre-programmed standalone unit.

During testing, stress and strain data for compression/tension of the sample are recorded and analyzed. The data is usually displayed in the form of graphs, which are then analyzed and the relevant parameters are displayed in a spreadsheet. These parameters will be selected to be measured as important material properties to determine whether the material being tested is fit for purpose or conforms to established standard values.

Measurements outside of quality boundaries can lead to physical failure during use or quality changes during storage, with possible safety implications and ultimately damage to the product and/or company’s reputation.

5. What industries can the material testing machine be used for?

Materials and therefore the requirements for material testing are everywhere, including the plastics, medical, paper and cardboard, leather and textile, automotive, medical devices, building materials, and electronics industries.

6. What are the characteristics of the material testing machine?

Materials testing machines can be configured for a variety of applications simply by selecting the appropriate load cells, sample grips, optional materials testing software, and accessories such as extensometers, heat cabinets, and high-temperature furnaces.

7. What are the applications of the material testing machine?

Material testing machines are suitable for quality control, production, laboratory, R&D, or education. The wide range of testing capabilities listed above means that there are different applications in the market, such as:

  • plastic
  • rubber
