Mechanical testing


Melytec LLC sells equipment for conducting mechanical tests. This is a vast category of devices used to determine the resistance of various materials and components made of such materials to deformation and braking under the force of applied loads. They can be used to determine such important parameters as ductility, tensile strength, yield strength, elastic modulus, forgeability, etc., and to understand how the properties and structure of metal, plastic, and ceramics change under various stresses. This equipment is used in the machine building industry, at metallurgical enterprises, and in research laboratories.

Main types of experiments:

All the various research studies can be divided into two groups in accordance with the actual load application time:

  • static;
  • dynamic.

In static tests, a load is constantly applied to specimens. Dynamic mechanical tests imply that the specimen is exposed to the rapidly changing load applied with a different speed.

The most popular examination types that are performed using such equipment are bend, tensile, compression and torque tests. They are often used for weld inspection.

Static tests mostly use the following equipment:

  • tensile machines which apply tensile stress to parts and are often used for weld inspection;
  • presses which apply compression with a certain force and can be used for longitudinal and transverse bending test;
  • versatile equipment which applies stresses of various types.

A testing machine which applies dynamic impact force is called an impact testing machine. The most popular devices in this category are pendulum impact testing machines. They are widely used for impact tests. The operation principle of an impact testing machine is quite simple: a pendulum rotating around a fixed axis falls onto the specimen from a certain height, and then makes a reverse pendulum motion which is recorded on a special scale. Many devices of this type are equipped with an electronic unit for storing information obtained during the testing.

A separate examination category includes endurance tests of materials with constant or changing loads. They study high-cycle fatigue (HCF) caused by continuous operation at loads close to or exceeding the yield limit. Our company offers machines for testing turbine blades which can simulate this effect in laboratory conditions.

A wide range of equipment

Our catalog contains a variety of devices which differ in purposes, principles of operation, design features, the presence or absence of an electronic unit and other parameters. In particular, we offer equipment designed for working with various materials:

  • plastics testing machine;
  • ceramics testing machine;
  • composites testing machine;
  • versatile testing machines.

Another category of devices is specialized machines. These are machines for vacuum, liquid media, high-temperature and other tests.

Melytec LLC also sells a variety of accessories for testing mechanical stress resistance. These include grips, remote control systems, strain gauges (extensometers) and many other types of equipment. Indexing mechanisms can be used for marking specimens of various shapes — both flat and cylindrical.

The advantages of electromechanical tensile-testing machines and other versatile and specialized equipment presented in this catalog section:

  • ease of operation;
  • a wide range of possible loads;
  • reliability;
  • compliance with modern standards.

Many machines are equipped with electronic units. These simplify the operation significantly, improve measurement accuracy and allow to store digital information.
