Product Description
The foot warmer bending test machine is a specialized device designed in accordance with standards such as GB 4706.80:21.101 and IEC 60335-2-81:21.101 to simulate the bending stresses experienced by the leg area during normal use of foot warmers, thereby assessing their mechanical strength and structural safety. It can automatically perform cyclic testing and record any failures, making it a core testing instrument for foot warmer safety certification.
Core Testing Principles and Procedures
- Specimen Installation: Secure the foot warmer to the support platform and place the leg region on a 300×150×20 mm glued laminated timber board with rounded edges.
- Load setup: A wooden board, a movable support, and the load have a total mass of 30 kg. The wooden board is allowed to fall freely from a height of 200 mm above the base, causing the leg area of the foot warmer to bend and compressing the device between the wooden board and the supporting surface.
- Cyclic testing: Perform 1,000 bending cycles at a rate of 6 cycles per minute; for leg-area foot warmers, test only the upper surface.
- Result determination: After testing, inspect the structure for fractures or deformations, and check the electrical system for faults such as short circuits or leakage.

Core Functional Features
- Automated testing: After setting the parameters, the test runs automatically and stops when the specified number of iterations is reached, eliminating the need for manual supervision.
- Fault Monitoring: Real-time detection of electrical faults, structural cracks, or deformations during testing, with automatic alarm activation and shutdown.
- Precise counting: LCD displays the number of cycles, with power-off memory and traceable data.
- Highly adaptable: compatible with foot warmers both with and without leg coverage; standard wood board dimensions; rounded edges to prevent additional injury.
- Robust Structure: Driven by servo motors or solenoids, the system ensures precise drop height and load accuracy, with a rigid support platform that delivers excellent test repeatability.
Application Scenarios
- Foot-warming device manufacturers: Conduct factory-outgoing inspections and structural optimization during the R&D phase to proactively identify structural and electrical safety hazards.
- Third-party testing agency: Provides compliance test data for the safety certification of foot warmers and issues a test report.
- Quality Supervision Authorities: Conduct random market inspections to verify that products comply with safety standards, thereby ensuring consumer safety.
