Cold Bending Testing Machine It Can Be Used For Testing In Various Scientific Research Institutions And Factory And Mine Central Laboratories

Product Overview
The cold bending testing machine is one of the climate simulation chambers, suitable for testing the adaptability of various products or materials, household appliances, instruments, meters, components and other electrical and electronic products under high and low temperature environments. It can be used for testing in various scientific research institutions and factory and mine central laboratories. This testing machine is suitable for cold bending tests of wires. First, set the temperature of the test chamber. When the temperature reaches the set value, take a sample of a certain length and put it in. After the test time, immediately wind it around a circular rod of the specified diameter at a uniform speed, then take out the sample and check if there are any cracks or fractures.

Product features
The unique balanced temperature regulation method enables the equipment to achieve high-precision and highly stable temperature control.
The studio is made of high-quality stainless steel plates, and the sample shelves are also made of stainless steel, which is corrosion-resistant and easy to clean.
3. The temperature controller of the equipment features high precision and stability, PID self-tuning and LED intuitive display, ensuring precise control of the equipment.
The equipment is equipped with over-temperature protection and timing functions. When the timing ends or an alarm is triggered, the power supply will be automatically cut off to stop the operation of the equipment, ensuring the safety of the equipment and personnel.
The sealing strips of the equipment are made of silicone material, which features good toughness and is not prone to deformation or stickiness in high and low temperature environments.
The box body is made of stainless steel, with uniform color and a beautiful and elegant appearance.

There is no strong vibration around. '
There is no direct sunlight or direct radiation from other heat sources.
There should be no strong air flow around. When the surrounding air is forced to flow, the air flow should not directly blow onto the box.
There is no strong electromagnetic field influence around.
There should be no high-concentration dust or corrosive substances around.
To ensure the normal operation of the equipment and the convenience of operation, in addition to keeping the equipment placed horizontally, a certain space should be reserved between the equipment and the wall or objects.

Safety Precautions
To protect the equipment and ensure the safety of the test, please install an external protective mechanism.
The equipment should be installed horizontally and it is strictly prohibited to place it at an Angle.
Non-professionals are not allowed to disassemble or repair the equipment system.
During the test, do not open the box cover unless it is absolutely necessary, otherwise it may cause personal injury and malfunction of the system.
The equipment should be reliably grounded to ensure safety and the effective control of the protection control system.
If a heating sample is placed inside the device, please use an external power supply for the sample. Do not directly use the device's power supply.
Tests on explosive, flammable and highly corrosive substances are strictly prohibited.
The power circuit breaker of the equipment, the over-temperature protection system, the provision of equipment test pieces, and the safety protection of the operators should be inspected regularly.
You can operate this equipment only after reading the manual carefully.
When the machine is operating below 0℃, the box door should not be opened. Otherwise, frost and water will form on the evaporator and other parts inside the box, reducing the efficiency of the machine.
After the low-temperature operation is completed, please set this machine to 60℃ and conduct a 30-minute drying operation.
This machine is equipped with a timer switch. When the temperature inside the box reaches the test temperature, if timed operation is required, please turn it on. After the set time is reached, the machine will automatically cut off the power supply and send out a prompt signal.
During the youdaoplaceholder3 test, if the box door is opened, it may cause misunderstanding of the system PID and trigger the over-temperature protection. Please avoid this.
After the cold machine switch is turned on, the equipment enters a delayed protection state. Do not forcibly start it in this state.
Do not change the set parameter values during the operation of the instrument; otherwise, it will be difficult to ensure the control accuracy of the equipment.
This equipment is equipped with an observation window and a lighting device for observing the test conditions inside the laboratory. This lighting device is only used for observation.
