FSR-01 Shrink Force and Ratio Tester

The FSR-01 Shrink Force and Ratio Tester is a state-of-the-art instrument designed for accurately measuring both the shrink forces and shrinkage ratios of heat shrinkable films. These films, which undergo extrusion and stretching (hot drawing) during their manufacturing process, maintain their stretched state even after cooling. When reheated to the temperature where the initial stress was introduced and subsequently fixed, the stress is released, causing the film to contract or "shrink back." T

Applications

The FSR-01 Shrink Force and Ratio Tester is a state-of-the-art instrument designed for accurately measuring both the shrink forces and shrinkage ratios of heat shrinkable films. These films, which undergo extrusion and stretching (hot drawing) during their manufacturing process, maintain their stretched state even after cooling. When reheated to the temperature where the initial stress was introduced and subsequently fixed, the stress is released, causing the film to contract or "shrink back." The film can be categorized as either biaxially oriented (stretched in two directions) or uniaxially oriented (stretched in one direction) based on the specific manufacturing treatment applied.

 

Testing Process

  • Heating the Air Oven: The well-insulated air oven is heated to a precise set temperature. Two samples are placed separately on two test stations for shrinkage rate and shrink/contraction force testing.
  • Temperature Probe Measurement: A temperature probe located in the measuring area provides accurate reference temperatures. The air oven automatically covers the sample area, ensuring controlled testing conditions.
  • Force and Shrink Rate Measurement: The force and shrink rate are measured as the shrinkage temperature is reached when the maximum shrinking force is attained. The oven is lifted once the force decreases by 15-30%, and time is recorded.
  • Shrinkage Ratio Assessment: The assessment of the shrinkage ratio is performed at the mean time, ensuring precise evaluation of film properties.

 

Technical Features

  • PLC Control and HMI Touch Screen: Ensures industrial-level stability and user-friendly operation.
  • Well-Insulated Air Oven: The air oven is excellently insulated, capable of automatic lowering and lifting, which enhances testing precision.
  • Non-Contact Shrink Ratio Measurement: Achieved through a non-contact method, improving accuracy and reliability.
  • Real-Time Display: Displays shrinking force, contracting force, and shrinkage ratio, allowing for immediate analysis and monitoring.
  • Elimination of Interference Factors: Effectively eliminates irrelevant interference factors like friction and cool air, ensuring the accuracy of results.
  • Stable Heating System: The heating system is stable and well-balanced, maintaining consistent and controlled test conditions.
  • Easy Sample Loading: Simplifies sample loading, streamlining the testing process and reducing setup time.
  • High-Resolution Sensors: Equipped with high-resolution force transducers and thermometers, guaranteeing precise measurements.
  • Connectivity and Software: Includes an RS232 port for data connectivity and offers optional professional software for advanced data analysis and reporting capabilities.
