    The tester is also applicable in other specialized industries such as automotive manufacturing, textiles, and consumer electronics, where tensile strength, elongation, and tear resistance are crucial properties. The film tensile and film elongation tests are used to evaluate the material’s ability to withstand tension and deformation under load, ensuring optimal performance in end-use applications.

    Why You Must Need the TST-01 Tensile and Elongation Tester

    In the packaging and material manufacturing industries, tensile and elongation tests are essential to determine the strength and durability of materials. The elongation rate of a material gives insights into its flexibility and stretching potential before failure. Without these crucial measurements, manufacturers risk using materials that may not perform as expected in real-world applications, leading to product failures, safety hazards, and costly reworks.

    With the TST-01 Tensile and Elongation Tester, professionals can assess the tensile strength and elongation at break of materials, ensuring that packaging solutions meet industry standards and customer expectations. The elongation at break test helps to identify whether the material can maintain its integrity under stress and is especially critical for thin films and packaging that may need to stretch during handling or transportation.

    Working Principle 

    The TST-01 is a CRE type tensile testing machine (constant-rate-of-extension) that operates based on a precision ball lead screw mechanism, which ensures consistent movement and accurate control over the testing speed and displacement. The tester applies a constant speed to the sample, gradually elongating it while measuring the force required to continue stretching. As the material stretches, the machine records the tensile force and elongation rate, allowing for real-time monitoring of the sample’s behavior under stress.

    The process begins by clamping the sample between two grips. The machine then applies a force that stretches the material, recording the force and elongation at various intervals. The elongation at break is determined when the material finally fails or breaks. The results are then displayed on the HMI touch screen or can be printed via an optional microprinter or exported via RS232 data output for further analysis.

    Test Process:

    1. Specimen Preparation: A sample of the film is cut to size 150mm*150mm or a 150mm wide roll sample, and its thickness is measured.
    2. Probe Application: A pear-shaped TFE-coated probe is used to apply force to the film. The probe penetrates the material at a low rate of speed 250mm/min.
    3. Force and Penetration Measurement: The maximum force required to puncture the film, along with the penetration distance are recorded.
    4. Data Analysis: The data collected during the test provides insight into the strength of the film’s puncture.

    This method ensures that the tester simulates real-life conditions where the film may be subjected to puncture or stress from sharp objects or mishandling.

    Advantages of the Protrusion Puncture Tester

    The TST-01 offers precise displacement control with 0.01mm accuracy in displace and better than 0.5% force reading accuracy, ensuring reliable test results across materials.

    The 7-inch HMI touch screen provides intuitive control, making operation simple for both new and experienced users.

    In addition to tensile and elongation tests, the machine can perform other essential tests like peeling, seal strength, and puncture force.

    The tester can accommodate various test samples and materials, from thin films to robust composite materials.

    Results can be displayed on the screen, printed on a microprinter (optional), or transmitted to external devices via RS232 for detailed analysis.
