Overview
Shoe material low temperature folding test machine (brand: AISRY, model: NBC-FOLD600, product name: vertical low temperature folding test machine) is a kind of equipment used to test the folding performance of finished shoes, rubber, plastic, sole, synthetic leather and other materials in low temperature environment. The equipment evaluates the cold resistance, bending performance and durability Reliability of materials or finished products by simulating low temperature climate or cold area use conditions.
Features
1. Low temperature environment simulation: It can simulate the low temperature use conditions in winter or extremely cold areas.
2. Multifunctional fixture compatibility: made of stainless steel, it can be equipped with a variety of fixtures such as finished shoes resistant to bending, outsole resistant to bending, leather resistant to bending, etc., to adapt to different test requirements.
3. Precise control system: equipped with a control system to precisely control the temperature (control accuracy +/- 0.3 ° C) and test parameters to ensure test accuracy and repeatability.
4. Data logging and analysis: Equipped with a data logging and analysis system, it can monitor the test process in real time and process the analysis data.
5. Multiple safety protection: with thermal protection shutdown, leakage protection shutdown, over-temperature protection, overload protection and other functions.
6. Efficient and stable refrigeration: using R404 environmentally friendly refrigerant and original fully enclosed Compressor, the cooling speed is fast (about 45 minutes at room temperature to -30 ° C).
7. Durable structure: The inner and outer boxes are made of stainless steel #304 material, and the thermal insulation material is hard foam and Glass cotton.
Principle
The testing machine reduces the temperature of the test inner box to a set low temperature (such as -30 ° C) through a refrigeration system (using R404 environmentally friendly refrigerant and a fully enclosed Compressor) to simulate a cold environment. Under low temperature conditions, the equipment is driven by a belt-free multi-import gear reduction motor, so that the installed specific fixtures (such as finished shoes bending-resistant fixtures, outsole torsion-resistant fixtures, etc.) repeatedly fold or bend the sample to simulate the force deformation of the material in actual low temperature use. The control system precisely maintains temperature stability and records data such as the number of folds, so as to evaluate the material's folding resistance performance and fatigue resistance at low temperature.
Applications
Finished shoe testing, rubber material testing, plastic material testing, sole testing, synthetic leather testing
Standards
ASTM-D1790、D1593、1052、JIS-K6545、HB-T2877、CNS-7705、ISO 20344、GB/T20991-2007
Steps
1. Prepare samples: Select samples of finished shoes, rubber, plastic, soles or synthetic leather according to test standards.
2. Installation fixture: According to the test requirements (such as finished shoes resistant to bending, outsole resistant to bending, leather resistant to bending), select and install the corresponding fixture.
3. Place the sample: Install the sample correctly to the corresponding fixture station.
4. Setting parameters: Set the target temperature (e.g. -30 ° C), the number of tests, or Miscellaneous related parameters through the control system.
5. Start test: Close the box door, start the equipment, and the refrigeration system starts to work. After reaching the set temperature, the motor drive fixture starts to perform folding test.
6. Monitoring and recording: Observe the test process through the window, and the data recording system automatically records the test data (such as the number of folds).
7. End of analysis: After the test reaches the set number of times or the sample is damaged, the equipment stops, the sample is removed, and the test data is analyzed to evaluate the folding performance.
Notice
• power requirements: Please ensure that the AC380V 50Hz or AC220V 50Hz power supply is used and meets the device power consumption (4-6KW) requirements.
• Safety protection: The equipment has multiple protection functions, but it is still necessary to avoid electric shock or mechanical injury during operation.
• Compressor protection: The Compressor starts with a 5-minute delay protection, do not start and stop frequently.
• Sample installation: Ensure that the sample is firmly installed on the fixture to prevent peeling from affecting the results or damaging the equipment during the test.
• Temperature Uniformity: Note that the Temperature Uniformity in the box is +/- 2 ° C. This factor should be considered when placing the sample.
• Maintenance: Regularly check the refrigerant, Compressor and electrical system to ensure the stable operation of the equipment.
• Size and weight: Dimensions of the equipment are large (about 1100 * 1050 * 1600mm) and the weight is 420kg. It is necessary to ensure that the place is stable and easy to dissipate heat.
• environment requirements: equipment operation will generate heat, should be placed in a well-ventilated environment.
