MIT Folding Endurance Tester For Packaging Paper Folding Resistance ISO 5626 Paper Testing Instrument

Introduction to the MIT Folding Endurance Tester

The MIT Folding Endurance Tester (NZD-01) is an advanced and reliable instrument designed to assess the folding resistance performance of sheet materials such as paper, cardboard, and tobacco sheets with a thickness of less than 1.25 mm. This critical testing instrument is essential for industries like packaging, paper manufacturing, and tobacco production, as it helps evaluate a material's durability when subjected to repetitive folding and bending stresses.

The MIT Folding Endurance Tester works by subjecting specimens to double folding under standardized tension conditions. The key metric, fold endurance, is calculated by measuring the logarithmic value (base 10) of the number of double folds at the point when the specimen fractures. The higher the fold endurance value, the more resistant the material is to damage from bending and folding. This valuable data is used by manufacturers and researchers to choose or improve materials based on their durability and performance.

In the packaging industry, the MIT Folding Endurance Tester is crucial for ensuring that packaging materials, such as cardboard and paper, maintain their strength and integrity throughout handling, storage, and transportation. Additionally, it is indispensable in the production of tobacco sheets, where folding resistance plays a vital role in quality control.

Technical Features of the MIT Folding Endurance Tester

• Adjustable Folding Rate: 20 to 200 double folds per minute, allowing for customized testing based on material requirements.
• Versatile Tension Weights: The tester includes various tension weights, offering flexibility for different materials and test conditions.
• Color Touchscreen Operation: A user-friendly color touchscreen interface provides easy operation and precise control over the test settings.
• Multiple Folding Heads: Equipped with various folding heads to accommodate a wide range of samples, ensuring versatility across different materials.
• Built-in Micro Printer: A modular integrated thermal printer allows for quick and accurate test result documentation.

Test Principle of the MIT Folding Endurance Tester

The operation of the MIT Folding Endurance Tester begins with leveling the instrument and positioning the oscillating folding head vertically. A weight is placed on the plunger, applying the required tension (typically 9.81 N) to the specimen. The tension is checked and adjusted using a load indicator. The test piece is clamped securely and precisely in the jaws, ensuring the surface is flat and aligned. Once the plunger lock is released, the specified tension is applied to the sample, and the folding process begins. The test continues until the specimen breaks, at which point the counter automatically stops. The number of double folds required to fracture the material is recorded.

Industry Standards and Compliance

The MIT Folding Endurance Tester complies with several global standards, including:

• ISO 5626: Standard for folding endurance testing.
• TAPPI T511: Test method for folding endurance of paper.
• GB/T 457: Chinese standard for paper testing.
• QB/T 1049: National standard for folding endurance testing.

These certifications ensure the tester's accuracy, reliability, and compliance with industry standards.

Key Configuration Options

• Standard Configuration: Includes the MIT Folding Endurance Tester (NZD-01), a paper roll, a manual, a calibration certificate, and a power cord.
• Optional Configuration: Non-standard jaws for specialized testing requirements.
