A dynamic testing machine is an electrical system-based machine that has a high-frequency servo hydraulic testing mechanism. The main goal of these machines is to determine the durability of products and materials. It helps in determining if the material or product is compatible to compress, alter, or tensile. Most of these machines are electrical, but there are servo hydraulic actuators. These actuators are great for high loads or fatigue testing applications.
These machines comprise various kinds of grips. Below are some of the grips utilized for the dynamic testing machine:
Bollard Grip
These grips are used for tensile tests on various kinds of fabrics, yarns, and fibers. This testing machine helps to know how much such materials can last. To use this grip, the materials like fabric or yarn, are tied to various ends of the drip. After this, the grips are pulled in the opposite direction. The main purpose of this grip is to determine the durability of fabrics, yarns, and fibers.
Three-Point Bending Fixture And Four-Point Bending Fixture Grip
These grips in the dynamic testing machines are used for checking the bending characteristics of the products or materials. It helps to know how much the material or product can bend till it breaks. The machine helps in carrying out clockwise as well as anti-clockwise analysis. To carry out this kind of testing, the machines seek the help of dynamic torsion and static.
The three-point bending test is done by putting the peak stress on the mid-point of the material that is being tested.
On the other hand, a four-point bending test is done by pressing along an extended region of the material.
Fluid Bath Grip
The fluid bath grip of the dynamic testing machine is utilized to check how the materials or products react at various temperatures of water. This testing is done by submerging the material or product. It helps in finding how resistant the products and materials are to water. Such kind of testing is done to find out if the specific product or material is water-resistant or waterproof.
Compression Plates Grip
It is the grip used for checking the compression levels of products or materials. For carrying out this testing, the material or the product is placed between two plates. After this, the pressure is applied on both sides. By carrying out this test, one can find how much pressure a product or material can take before breaking.
Temperature Chamber Grip
Such a kind of chamber grip helps in testing the durability and sustainability of the material or product at various temperatures. It helps to know how long a product or material can sustain at various temperatures.
Why These Machines Are Used?
The different grips of the dynamic testing machine help in testing the products or materials in different ways. Once the testing is carried out, it helps the manufacturers to decide if the product can be approved or disapproved before going ahead with the mass production. When positive results are obtained using this machine, instructions can be easily framed to handle the specific product or material for further procedure. Such instructions are usually found on the packaging.
If you plan to get a dynamic testing machine, you will be glad to know several companies have come up with such machines. Due to this, you can get a wide range of choices to select from. However, before going ahead with selection, you must know your needs first. Think of the specifications and accessories that you would like to have in such a machine. Based on these, ask for quotes from several companies. Make sure you compare the prices based on the accessories and specifications you want. Also, do not forget to ask for a demo of the machine. Most importantly, read reviews about the company and the machine. Considering all these you will surely be able to find the right machine for your needs.
