Description

Digital Tensile Strength Tester

The Digital Tensile Strength Tester is a versatile material testing machine designed to evaluate the tensile strength, tear strength, peel strength, and bond strength of different materials. The machine can be configured with suitable grips and fixtures for testing rubber, wire, plastic, films, tapes, and other materials.

Globe Tex Digital Tensile Strength Tester uses a motor-driven screw mechanism to move the fixtures at a controlled speed. The test specimen is securely held between the upper and lower fixtures, and the upper fixture moves upward to apply tensile force to the specimen. The applied force and displacement can be monitored during the test, helping users evaluate the mechanical performance of the material.

The machine features a 500 kg force rating, digital force display, peak hold facility, overload protection, emergency stop, and upper and lower limit switches for safer operation. Fixed or variable traverse speeds can also be provided according to customer requirements.

Working Principle

The Digital Tensile Strength Tester operates using a motor-driven screw mechanism that controls the movement of the test fixtures.

The specimen is positioned and securely held between the upper and lower grips. Once the test begins, the upper fixture moves upward at the specified traverse speed, applying a controlled tensile force to the specimen.

As the specimen is stretched, the machine measures the applied force and displacement. The digital display allows the operator to monitor the test results, while the peak hold facility can retain the maximum force achieved during the test.

Depending on the material and fixture configuration, the same testing platform can be used for tensile, tear, peel, and bond strength evaluation.

Technical Specifications

Testing Capabilities

The machine can be used for different mechanical testing applications depending on the selected grips and fixtures.

Tensile Strength Testing

Tensile testing determines how a material behaves when subjected to a pulling force. The specimen is held between the grips and stretched until the required test endpoint, allowing the user to evaluate its resistance to tensile loading.

Tear Testing

With suitable fixtures, the machine can be used to evaluate the resistance of materials to tearing. This can be useful for materials where tear strength is an important performance characteristic.

Peel Testing

The tester can also be configured for peel testing of suitable materials such as films, tapes, bonded materials, and other flexible products where peel resistance needs to be evaluated.

Bond Strength Testing

Suitable grips and fixtures allow the machine to perform bond-strength evaluation of materials or assemblies where the strength of a bonded connection needs to be determined.

Applications

The Digital Tensile Strength Tester can be used across a wide range of industrial and laboratory testing applications.

Typical applications include:

• Rubber testing
• Plastic testing
• Film testing
• Tape testing
• Wire testing
• Tensile strength evaluation
• Tear strength testing
• Peel strength testing
• Bond strength testing
• Material quality control
• Research and development
• Laboratory testing
• Production quality control

The appropriate grip, fixture, test speed, specimen dimensions, and test procedure should be selected according to the material and applicable testing standard.

Grips and Fixtures

The performance of a tensile testing machine depends significantly on the correct selection of grips and fixtures. The supplied grips are designed to hold the specimen securely during testing and help minimize premature slipping, wear, or damage during specimen holding.

One set of grips is provided free of cost with the machine. Additional grips and specialized fixtures can be selected according to the customer’s material and testing requirements.

Safety Features

The machine incorporates several safety features to help provide controlled operation during testing:

• Emergency Stop: Allows the operator to stop the machine quickly when required.
• Overload Protection: Helps protect the machine against excessive applied loads.
• Upper and Lower Limit Switches: Help prevent unintended movement beyond the specified travel limits.

These features support safer operation during routine laboratory and industrial testing.
