Leather Product High and Low Temperature Stretch Testing Machine

The leather product high and low temperature stretch testing machine is a specialized device used to test the mechanical properties of leather under extreme temperature conditions, particularly its tensile strength, elongation, and breaking point at both high and low temperatures. This equipment simulates the effects of different environmental temperatures on leather products and is widely used in leather product development, quality control, and material performance evaluation.

1. Adjustable Testing Space

• The testing space of this machine can be adjusted according to the size of the leather sample, suitable for testing both small and large leather products. The adjustable testing space ensures that the machine can efficiently and accurately complete tests for leather samples of various shapes and sizes.

• The adjustable space design ensures the machine can perform testing on leather samples of various dimensions and shapes effectively.

2. High and Low Temperature Environment Simulation

• The machine is equipped with a high-efficiency temperature control system capable of conducting stretch tests in a temperature range from -70°C to 200°C, simulating various extreme temperature conditions. The system allows for rapid heating and cooling, ensuring temperature stability and precise control during testing.

• The temperature control system is designed to simulate the physical behavior of leather in different environments, such as extremely cold or hot conditions.

3. Rapid Temperature Change Function

• The high and low temperature stretch testing machine can achieve rapid temperature changes, usually exceeding 10°C per minute. This function is suitable for simulating thermal shock or scenarios with sudden temperature fluctuations.

• Rapid temperature changes more realistically simulate the temperature fluctuations leather products might encounter in real-world use, providing more accurate performance data.

4. Precise Stretch Testing

• The machine uses high-precision load sensors and displacement sensors to accurately measure the stress, strain, tensile strength, and elongation of leather samples during the stretching process.

• During testing, the machine records real-time data of the leather sample’s stretch behavior and temperature changes, helping to evaluate the material’s properties under different temperature conditions.

5. Intelligent Control and Data Analysis

• The machine is equipped with an intelligent control system, allowing operators to set test parameters such as temperature, stretch rate, and test duration via a touchscreen or computer. The machine will automatically conduct tests according to the set parameters.

• The device features a data acquisition system that records real-time test data and generates detailed test reports. Users can export data for further analysis as needed.

6. Safety Protection Design

• To ensure the safety of both the operator and the machine, the device has multiple safety protection measures in place. If the machine detects overheating, overloading, or other faults during testing, the system will automatically stop the operation and issue a warning.

• The machine also includes an automatic detection function for leather sample rupture to prevent damage to the machine when a sample breaks。
