A bursting strength tester is a specialized piece of laboratory equipment used to measure the bursting strength of materials, typically paper, paperboard, and cardboard. This test is crucial in industries like packaging, where the ability of a material to withstand internal or external pressure is essential for product integrity and safety.
Here's how a bursting strength tester typically works:
Sample Preparation: A small, circular or square sample of the material is cut and prepared for testing. The size of the sample can vary depending on the testing standards and the specific requirements of the material being tested.
Test Chamber: The prepared sample is placed in a test chamber or clamped between two circular clamps. One side of the sample is exposed to hydraulic pressure, and the other side is held in place.
Hydraulic Pressure: A hydraulic pump is used to apply pressure to the sample. The pressure is increased gradually until the sample bursts. The hydraulic pressure required to burst the sample is recorded as the bursting strength.
Measurement and Recording: The bursting strength is typically measured in units of pressure, such as pounds per square inch (psi) or kilopascals (kPa). This measurement provides information about the material's ability to withstand internal pressure without rupturing.
Calculation: The test results are often used to calculate other properties like burst factor or burst index, which can help in material characterization and quality control.
A bursting strength machine is essential tools for quality control and product development in industries where paper and paperboard materials are used extensively, such as in the production of packaging materials, cardboard boxes, and various paper products. They help ensure that materials can withstand the forces they may encounter during handling, transportation, and use, which is crucial for maintaining the integrity and safety of products. We can use the bursting strength of fabric .
Know More about digital bursting strength tester
A digital bursting strength tester is an advanced version of the traditional bursting strength tester, equipped with digital technology to provide more accurate and precise measurements. Here are some features and advantages of a digital bursting strength tester:
Digital Display: The most apparent feature is a digital display screen that shows the test results in a clear and easily readable format. This eliminates the need for manual reading and interpretation of analog gauges, reducing the chances of human error.
Data Logging: Many digital testers have the capability to store test data electronically. This allows for easy record-keeping, traceability, and analysis of test results over time.
Automatic Testing: Some digital testers are equipped with automated features, such as automatically applying pressure at a controlled rate until the sample bursts. This helps ensure consistent and repeatable testing procedures.
User-Friendly Interface: Digital testers often have user-friendly interfaces with intuitive controls, making it easier for operators to set up tests, input parameters, and initiate testing.
Data Analysis: Digital testers may offer built-in data analysis tools, allowing users to perform calculations and generate reports directly from the device. This can save time and enhance efficiency.
Calibration: Digital testers typically come with calibration options to ensure accuracy. They may also provide alerts when recalibration is needed, helping to maintain the precision of measurements.
Remote Control and Connectivity: Some advanced models may have remote control capabilities and connectivity options, allowing operators to monitor and control tests from a distance or integrate the tester with a broader quality control system.
Multiple Test Modes: Digital testers often offer various test modes to accommodate different testing standards and materials. These modes may be easily selected from the interface.
Safety Features: Digital testers may include safety features like overpressure protection to prevent damage to the tester and ensure operator safety.
Software Integration: Some bursting strength tester machine can be integrated with computer software for advanced data analysis and reporting.
Overall, digital bursting strength testers offer increased accuracy, efficiency, and ease of use compared to their analog counterparts. These features make them valuable tools for quality control and research in industries where the bursting strength of materials is a critical parameter. Here multiple bursting strength testers uses in different industries in 2023.
Business Situation in the world of Packaging
India is growing day-by-day with the growing infrastructure and economy; large numbers of goods are transported across and country and all over the world. These products are carried to multiple places in the form of corrugated boxes, cardboard cartons, and sacks. These goods face many hurdles at the time of shipment like bursting, compression, fall and drop, leakage of packets, etc. Hence, to ensure the quality of the packages, it is necessary to test the quality of the packages to make the packaging products burst proof.
Problems and Challenges faced by Packaging Industries
The products which are packed in the cartons and shipping boxes are of high value and are expensive enough. If the boxes are of inferior quality the cartons will burst at the time of transportation due to loading and unloading, storing and warehousing. This distortion enhances the cost of the material by 10 to 12 percent and trade returns. Moreover, it also leads to diminishing the brand image.
Solution to Measure the Strength of Products in Packaging Industries
Packaging Industries is working continuously to ensure the containers integrity to reduce the cost of packaging and, on the other hand, scientific quality check and proactive ensures that nothing will be damaged due to transportation and warehousing. Quality testing of packages also helps to ensure that the corrugated boxes and containers are of best quality. This results in considerable savings to the packaging industries. One of the best solutions that presto offers to the manufacturers in order to test the bursting strength of corrugated boxes made up of multi-layered and single-layered fiber-boards is known as carton bursting strength tester.
