Scénarios d'application
- Footwear product quality control: Test the flex cracking resistance of shoe soles and KPU shoe uppers to verify service life under daily walking conditions
- Automotive interior inspection: Verify the bending fatigue performance of dashboard components, door panel trim and buffer foam parts to avoid cracking during long-term use
- Industrial product testing: Inspect the repeated bending resistance of solid tire components, buffer blocks and sealing parts to meet dynamic working condition requirements
- Raw material formula verification: Test the flex toughness of different polyol and isocyanate systems to support formula optimization of low pressure polyurethane foaming machines
- Cold-region performance matching: Combined with low-temperature environment, verify the flex resistance of products under cold climate conditions
Core Quality Assurance Advantages
1. Full-Process Fatigue Control, Reliable Long-Term Use
From raw material screening to finished product delivery, flex fatigue performance is verified at each key node to effectively avoid cracking and damage after repeated bending, ensuring the long-term service life of delivered products.
2. Standardized Test Conditions, Authentic and Comparable Data
Adjustable bending angle and stable test frequency ensure consistent test conditions for each batch. With regular third-party calibration, the test results strictly comply with international mainstream standards, and the data is authoritative and comparable.
3. Support Formula Debugging, Shorten Product Development Cycle
With independent flex testing capability, we can quickly verify the bending performance of different formulas and process schemes when matching foaming equipment solutions for customers, accelerating the landing of customized products.
4. Strict Factory Inspection, Reduce After-Sales Quality Risks
Each batch of delivered products for dynamic working conditions has passed sampling flex test, which effectively reduces quality objections caused by insufficient bending resistance and lowers customer application risks.
5. Complete Testing Matrix, Multi-Dimensional Quality Guarantee
In addition to the flex tester, we are also equipped with tensile tester, peel strength tester, brittleness temperature tester and other testing equipment to cover all-round performance verification of polyurethane products.
6. Linked Production Process, Optimize Durability Scheme
Combined with rich polyurethane foaming process experience, we can adjust equipment parameters and formula schemes according to test results to help customers achieve the best balance between bending durability and production cost.
