Semi-Automatic Sliding Door

Operating Principle

Unlike manual or fully automatic doors, our Semi-Automatic Sliding Door combines manual opening with automatic closing during operation. Its underlying mechanism can be explained by breaking down the process into several distinct stages.

The first stage is opening. Users can initiate the opening sequence by lightly pushing the door leaf, pressing a wall-mounted button, swiping an access card, or utilizing other designated methods.

Upon receiving this command, the control system activates the motor, causing the door to slide open automatically until it reaches its fully open position. Since no continuous physical effort is required, this offers greater convenience compared to manual doors. During the opening cycle, the door remains stationary in the open position for a specific duration; this holding time is fully adjustable.

Finally, once the preset delay period has elapsed, the door automatically and smoothly closes, subsequently locking securely.

Why do we recommend Semi-Automatic Sliding Doors for areas with low to moderate traffic?

1. No Electrical Power Required

Semi-Automatic Sliding Doors feature a self-contained power mechanism; they rely on mechanical energy storage to execute the closing motion. This eliminates the need for a mains power connection, thereby saving energy and reducing wiring costs.

In the event of a building power outage or an emergency, the door retains its full closing functionality, ensuring the airtight integrity of fire compartments or cleanroom environments.

2. Smooth Damping Technology

OWNIC’s semi-automatic doors are equipped with high-quality hydraulic damping buffers. During the final stage of closing, the door decelerates significantly to settle gently into place, effectively preventing pinch injuries to personnel and eliminating noise caused by forceful impacts.

Thanks to our precision-engineered tracks and rollers, the initial opening resistance is minimal; medical staff and patients alike can open the door with a single, light push.

3. Low Maintenance Costs and Exceptional Longevity

Compared to fully automatic doors, the semi-automatic design eliminates the need for complex motors, controllers, sensors, and drive belts. The product features a robust mechanical structure with an extremely low failure rate. OWNIC’s mechanical components have undergone rigorous fatigue testing—exceeding 3,000,000 cycles—ensuring that performance remains stable even after years of high-frequency use.

4. Airtight and Dust-Resistant Performance

After every opening cycle, the semi-automatic door reliably returns to a fully closed position. When combined with our proven sealing strip technology, the system effectively blocks out dust and odors.
