The FSR-01 Shrink Force and Ratio Tester serves the purpose of measuring both the shrinking forces and shrinkage ratio of heat shrinkable films. These films are typically created through extrusion and stretching (hot drawing) during their manufacturing process, retaining this stretched state even after cooling.

When the heat shrinkable film is reheated to the temperature at which the initial stress was introduced and subsequently fixed during its production, this stress is released, causing the film to contract or "shrink back." Depending on the specific manufacturing treatment applied, the film can be categorized as either biaxially oriented (stretched in two directions) or uniaxially oriented (stretched in one direction).

1. A well-insulated air oven is heated to the set temperature. The two samples are placed separately on two test stations, for shrinkage rate and shrink/contraction force testing. 

2. A temperature probe is located to measuring area, to give result as reference temp. The air oven is driven down automatically to cover the sample area. The force and shrink rate are to be measured and the shrinkage temperature is reached when the maximum shrinking force is attained. 

3. When this force has decreased by around 15%~30%, the air oven is lifted and time is recorded. 

4. The assessment of shrinkage ratio is performed at the mean time.

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.
