The MAGMA test system measures the hot tack and heat seal properties of film used in flexible packaging, bags and pouches. Under the control of Pilot software, MAGMA automatically creates and tests three heat seals under a programmable range of pressures, temperatures, dwell times and peel rates. The system automatically tabulates and plots statistics such as heat seal strength versus temperature, hot tack strength versus temperature, and averages and standard deviations of force data.
The test instrument follows the test methods described in ASTM F1921, ASTM F2029 and ASTM F88 for hot tack and heat seal testing, and offers capabilities even beyond those standards.
With its three integrated test stations, easy to use operation, and precision measurement and control system, the MAGMA is by far the most productive hot tack and heat seal test system available anywhere.
The MAGMA Hot Tack and Heat Seal Tester simultaneously tests three samples at each condition of pressure, temperature, dwell time, cooling time, and peel rate. During the peel operation three load cells measure the individual load responses of the specimens, instantly providing statistically relevant data. The result is data throughput that is far higher than other heat seal testers. Generate complete heat seal curves and statistics with astonishing speed.
Insert a specimen into each test station with a fast, single-motion action:
The MAGMA test system is engineered using only the finest transducers and control components. The high sensitivity load cell, independent temperature control for upper and lower sealing jaws, high precision seal pressure control, and high accuracy peel motion servo control are integrated into a precision test instrument.
Contributing to the MAGMA’s exceptional data quality is the highly repeatable specimen alignment achieved during specimen loading. Alignment repeatability is a result of the easy-to-use, side-entry grips described before.
Pilot software gives you powerful data analysis tools. Plot heat seal strength or hot tack strength versus temperature. View average force and standard deviation at each temperature. And analyze other test results too.
Test data can be exported in CSV format for viewing and further analysis using third party spreadsheet software. Once test data is saved, Pilot Viewer software can be used to remotely access and analyze the saved data.
Once a sample set is loaded, close the clear guard door and simply hit “Start” in the Pilot user interface. Under control of the Pilot software, MAGMA automatically seals the three samples, peels them, collects data and displays the results for instant review.
All tests are safely done behind the protective clear guard door. This provides protection against operator harm, as no moving machine parts are exposed during test execution.
Once the sample set has been tested, Pilot prompts the operator to open the guard door to remove the samples and then to load the next set.
The MAGMA is easy to calibrate, configure and maintain:
No specialized tools are needed. There’s no need to keep wrenches, extra fasteners, removal handles, and other tools for routine system configuration work
