Product Application:

The Office Chair Seat and Backrest Synchronized Motion Testing Machine is designed for testing seating products such as office chairs and stools. It performs mechanical performance tests, including free-fall impact and durability impact tests, under room temperature conditions. This machine is widely used in the office chair and furniture industry to evaluate the seat and backrest's performance under vertical forces, assessing their ability to withstand single impacts and fatigue durability. The goal is to improve product quality and ensure reliable performance.

Product Features:

1. Adjustable Height:

   • The seat testing mechanism typically includes manual or automatic lifting devices, accommodating chairs of various heights.
   • For instance, machines like TST Instrument's seat testing system offer a testing range from 200mm (minimum) to 1000mm (maximum) to meet diverse specifications.

2. High-Quality Components:

   • Ensures accuracy and stability with premium parts from trusted brands, such as:
     • APS high-strength aluminum alloy frames
     • Taiwan Bangshuo motors
     • Taiwan gear reducers
     • German Festo electric cylinders, sensors, air pipes, solenoid valves, and oil mist separators

3. Low Noise Operation:

   • Advanced machines feature noise-reduction technology, such as the patented electric cylinder silencing technology from TST Instruments, which reduces noise by up to 70% without compromising precision.

4. Modular Design:

   • Modular blocks allow flexible adjustment of loading forces. For instance, TST machines can adjust loading forces from 0N to 2000N.
   • When standards are updated or custom testing is required, upgrading the electric cylinder module is sufficient, enhancing versatility and scalability.

5. Precise Control and Data Logging:

   • Equipped with high-precision sensors and control systems, enabling accurate control of parameters such as force, speed, and stroke.
   • Provides detailed records of test data, including pressure distribution, deformation levels, and fatigue lifespan, offering reliable insights into chair performance.

Compliance Standards:

• EN 1728-2012 7.3: Combined static load test for seat and backrest
• EN 1728-2012 7.4: Seat front edge static load test
• EN 1728-2012 7.9: Seat and back durability test
