Pneumatic Sealing Machine
The Pneumatic Sealing Machine (Heat Seal Tester) is a high-precision laboratory instrument designed to determine the optimal heat seal temperature, dwell time, and pressure for various composite films. Built to guide industrial production and ensure packaging integrity, this instrument utilizes specially designed heat sealing jaws that fully comply with multiple national and international testing standards. It is an essential tool for manufacturers looking to achieve consistent sealing quality in flexible packaging materials.
Product Overview
Operating in full accordance with ASTM F2029, this Heat Seal Tester features a robust electro-pneumatic system for reliable and repeatable performance. The machine allows for the precise control of critical parameters, including temperature (up to 300 °C), pressure, and dwell time, through an intuitive operator interface. With its independent PID temperature control for both upper and lower jaws and a convenient pedal-switch start command, it provides a safe and highly efficient environment for testing large specimens or multiple samples simultaneously.

Advanced Features
Dual-Jaw PID Temperature Control
Equipped with independent PID controllers for the upper and lower jaws, allowing for unique temperature combinations. This ensures precise thermal regulation from ambient up to 300°C with high display accuracy.
Electro-Pneumatic Operation
Compliant with ASTM F2029, the system utilizes a smooth electro-pneumatic mechanism to apply consistent pressure (0.05Mpa to 0.7Mpa), ensuring uniform contact across the entire sealing area for reliable test results.
Pedal Switch Safety System
Features a dedicated pedal-switch start command that allows for hands-free operation. This provides a convenient and safe working environment for the operator while handling delicate composite film specimens.
Extended Sealing Surface
The machine features high-quality SS316 HD heaters with an extended surface area (20 X 300 mm). This design allows for the sealing of large specimens or the simultaneous testing of several samples to increase laboratory throughput.
