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.

The FPT-01 Friction and Peel Tester is a versatile instrument that serves as a valuable tool for quality control, product development, and research in industries dealing with a wide range of materials, from packaging to medical applications. System Description FPT-01 Friction and peel tester has a fixed loadcell position, with a protection cover. A movable plane is installed firmly to ball lead screw. The sled is to put on sample sticking to the plane, which is then connected to loadcell, with a filament. When performing peeling test, as the force is small, the right sample clamp is stuck to plane, using double side type. Then a separation action is performed to peel the sample and force is recorded during the process. Technical Features FPT-01 Friction and peel tester is a PLC-controlled unit with industrial-grade stability and operates through an intuitive HMI touch screen interface. The precision ball lead screw mechanism ensures consistent speed and displacement control. The system offers two distinct testing methods: one for measuring the coefficient of friction (COF) and another for assessing peeling forces. In COF tests, precise free speed settings are available, while peeling tests consider parameters that influence peeling results, such as initial and tail portions. Other features 1.

Background Impact resistance plays an important role in the performance of material subjected to regular shocking load or impact load. As this kind of load may cause rupture, cracking or deformation. There are various test procedures to evaluate the impact resistance of a material, such as dart impact, ball impact, pendulum impact, izod, charpy, tensile, etc. Application Falling ball impact tester measures the resistance performance of plates, sheets, and composites, films foils, paper etc. with less than 2mm thickness. By impact test, the material ability to resist external destruction can be indicated. User observes the destruction status of the test specimen after it has been hit by a falling weight that fell from a given testing height. Test Method A steel ball of known mass and diameter is released from a predetermined height, creating a controlled impact force on the test specimen (film or plastic sheet). The impact energy and the resulting damage or deformation are measured and analyzed to assess the material's impact resistance. Factors Influence Result 1. Drop Height: The height from which the steel ball is dropped is a critical parameter that can be adjusted to simulate different impact scenarios. 2. Ball Size and Mass: The size and mass of the steel ball are selected based on the specific testing standards or application requirements.
