How Do We Test Wheelchair Quality? TheInside Story of Our Factory’s Quality Assurance

Introduction:
Quality assurance in wheelchair manufacturing is not just about ticking boxes; it’s about ensuring each wheelchair can stand up to the challenges of daily use. Our wheelchairs undergo a comprehensive series of tests to ensure safety, durability, and comfort. This article provides an in-depth look at the extensive testing each wheelchair undergoes, highlighting our commitment to excellence.

1. Strength and Fatigue Testing:
   Every wheelchair is subjected to strength and fatigue tests. We simulate long-term use to ensure that the wheelchair can withstand repeated stress without compromising structural integrity. This includes over 6,000 drop tests with a 100KG dummy, ensuring no damage to any part of the wheelchair even when lifted and dropped from a height of 5-6 cm.
2. Front Wheel Wear Resistance:
   The front wheels, crucial for maneuverability, undergo wear resistance testing. This ensures they maintain performance even after extensive use.
3. Comprehensive Stability Testing:
   In our stability tests, we place a 100KG dummy in the wheelchair to assess its performance on various surfaces and inclines, guaranteeing user safety in different environments. We also test the effectiveness and safety of the brakes on slopes, ensuring reliable stopping and stability.
4. Frame Comprehensive Test Bench:
   The wheelchair frame undergoes rigorous testing on a specialized test bench. We check for any weaknesses in the frame’s design and construction.
5. Tensile Strength Testing:
   Tensile, or pull, tests are performed to measure the strength of the wheelchair’s materials and joints, ensuring they can bear the necessary weight and strain.
6. Vibration and Bump Testing:
   Vibration and bump tests simulate the impact of moving over rough surfaces. This ensures the wheelchair remains stable and comfortable on uneven terrain. The dynamic test includes a dual-wheel rotation test with 200,000 rotations, ensuring no frame or component breakage.
7. Pendulum Impact Testing:
   The pendulum impact test assesses how the wheelchair withstands sudden forces, such as collisions at 45 km/h with a 100KG dummy, ensuring the frame and components remain intact.
8. Salt Spray Test for Corrosion Resistance:
   Our salt spray tests evaluate the corrosion resistance of the wheelchair’s surface, ensuring parts and tubing withstand corrosion and maintain functionality and durability.
9. Seat and Back Pad Drop Impact Test:
   The durability of seat and back pads is tested through drop impact experiments, ensuring they maintain shape and comfort after heavy use.
10. Electric Motor Noise Test:
    For powered wheelchairs, we conduct noise tests on the electric motors to ensure a quiet, smooth operation.

Conclusion:
By detailing our diverse and meticulous testing procedures, we are committed to delivering wheelchairs that are dependable companions in everyday life. Our rigorous testing process is designed to provide peace of mind to our clients, affirming that every wheelchair from our factory is built to the highest standards of quality and reliability.
