The HK-561 Plastic Buckle Durability Testing Machine is designed to simulate the real-world usage of plastic buckles by repeatedly opening and closing them at a controlled frequency. This test evaluates the durability, strength, and overall quality of plastic buckles used in backpacks, bags, and other outdoor gear. It complies with QB/T5247-2018 and QB/T4117-2010 standards, making it ideal for quality control and product development.
* Simulates continuous opening and closing of plastic buckles under a set frequency.
* Automatically counts each cycle for accurate durability testing.
* Detects buckle failure, deformation, and fatigue performance.
* Provides data to improve buckle design and production quality.
* Backpack and outdoor gear manufacturing quality control.
* Luggage and handbag accessory testing laboratories.
* Plastic hardware R&D and performance testing.
* Standard compliance testing for fasteners and buckles.
1. Secure the plastic buckle sample in the test fixture.
2. Set the testing frequency to 25 ± 2 cycles per minute.
3. Select the target number of test cycles: 1000, 2000, 3000, or as specified by standards.
4. Start the machine and allow it to run continuously until the target cycle count is reached.
5. After testing, let the sample rest for 1 hour, then inspect for damage, deformation, or failure.
6. Record the test results, including changes or damage observed.
1. Left and Right Test Fixtures: The left fixture holds the upper buckle part and presses the locking mechanism periodically, while the right fixture holds the lower part and performs forward and backward movements.
2. Synchronization Mechanism: Ensures coordinated horizontal movement for precise buckle opening and closing actions.
3. Counter: Records each complete opening and closing cycle automatically.
4. Adjustable Frequency: Allows users to set test speed according to standards.
