FSR-01 Shrink Force and Ratio Tester

Application
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).

Test Process
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.

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.
