Tensile tester is really a machine utilized to measure ultimate tensile strength, elongation and lowering of the crossectional portion of the material by subjecting it to axial force. Quality is done to know how a material will answer different sort of forces from the field to ensure weakness are pinpointed and necessary remedial measures are delivered to prevent failure in manufactured goods.
A Universal Tensile testing machine, typically referred to as UTM, is trusted by laboratories to test the tensile and compressive strength of the materials. The main purpose of this tensile tester is defined maximum stretch limit of any material, before its breaks. It is accustomed to test strength of varied materials like rubber, plastic, steel etc, which are found in manufacture of different types of goods.
The Universal tensile testing machine helps to establish the ductility of metal. This property of metal allows it to retain its original shape as soon as the load is slowly removed, without any alteration. Through testing one can possibly understand the variety of elongation and breaking point (point-of-no-return to original shape). Tensile strength testing machine helps manufacturers of industrial garbage, semi-finished and finished goods get right details about the elongation, elastic limit, yield strength and yield reason for their materials and avert any operational failure due to undetected weakness inside the material. This machine ensures satisfactory compliance to industrial safety regulations and manufacturing practices.
The UTM has two crossheads, one is adjusted to accommodate the size of the specimen and yet another one is hydraulically or electromagnetically driven to make the tensile strain on the specimen. The machine generates enough force to fracture the specimen, in quick or slow method to mimic the action of force in actual field conditions.
Tensile tester measures minute alternation in dimensions to demonstrate exact behavior of the material under stress. This can help to create reliable testing report so that inherent weakness in the material are accounted and brought in consideration in the manufacturing process. Besides this tensile tester helps quality control engineers to establish the tensile breaking point or yield point of their finished goods before they are sent into the market. There are numerous types’ types of Universal tensile testing machine available in the market; nevertheless they generally have few common points which might be mentioned below:
• Anti-Backlash system
• Electromagnetic or Hydraulic powered movement of one crosshead
• Emergency stop through rocker, mechanical switch or computer
• Crosshead guidance system
• Quick disconnect load cell and fixture system
There are several suppliers of tensile testing machine in market and value in the tensile testers varies according to the technical features offered, models and the functionalities. It is in best interest from the user to thoroughly analyze the various models, their price and ascertain that the way a said machine will benefit them in optimum manner.
