Shrink Force and Ratio Tester for Plastic Film

FSR-01 Shrink Force and Ratio Tester Application
The FSR-01 serves to measure both shrinking forces and ratios of heat shrinkable films, typically made through extrusion and hot drawing during manufacture, retaining this state post-cooling. Upon reheating to the initial stress temperature, the film contracts or "shrinks back," categorized as biaxially or uniaxially oriented based on manufacturing treatment.

Test Process
1. Heat an insulated air oven to the set temperature. Place two samples separately on test stations for shrinkage rate and force testing.
2. Position a temperature probe for reference. The oven automatically covers the samples, measuring force and rate until the shrinkage temperature is reached.
3. When force decreases by around 15% to 30%, lift the oven and record time.
4. Assess shrinkage ratio in the meantime.

Technical Features
1. PLC Control and HMI Touch Screen: ensuring industrial-level stability.
2. Well-Insulated Air Oven: The air oven is excellently insulated and capable of automatic lowering and lifting, enhancing the precision of the testing.
3. Non-Contact Shrink Ratio Measurement: accomplished through a noncontact method, improving accuracy and reliability.
4. Real-Time Display: including shrinking force, contracting force, and shrinkage ratio, allowing for immediate analysis and monitoring.
5. Elimination of Interference Factors: Irrelevant interference factors like friction and cool air are effectively eliminated, ensuring the accuracy of the results.
6. Stable Heating System: The heating system is stable and well-balanced, maintaining consistent and controlled test conditions.
7. Easy Sample Loading: Sample loading is made easy, streamlining the testing process and reducing setup time.
8. High-Resolution Sensors: The system is equipped with high-resolution force transducers and thermometers, guaranteeing precise measurements.
9. Connectivity and Software: (optional) It includes an RS232 port for data connectivity and offers optional professional software for advanced data analysis and reporting capabilities.
