# Industrial Specification: Soft-Close Damper

## 1. Technical Definition
A hydraulic or pneumatic damping device that slows and quiets the final closing motion of a drawer.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-8.0 bar hydraulic pressure, 0.3-6.0 bar pneumatic pressure, 0.1-0.5 m/s closing velocity**. Failure boundary: **Hydraulic: 12.0 bar burst pressure, Pneumatic: 9.0 bar seal failure, Velocity: 1.2 m/s impact force exceeding 150 N**, Mechanism: **Hydraulic: Cavitation at vapor pressure &lt;0.02 bar absolute causing bubble implosion and surface pitting. Pneumatic: Adiabatic compression heating exceeding 120°C degrading elastomer seals (NBR/EPDM). Mechanical: Hertzian contact stress &gt;350 MPa at cam-follower interface causing spalling.**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Hydraulic fluid contamination with 15 μm+ particulate exceeding ISO 4406 18/16/13 | 8 | Spool valve stiction causing erratic damping profile (0.8-2.5 s variance vs 1.2±0.1 s spec) | Integrate 10 μm absolute filter with 0.3 bar ΔP bypass and magnetic plug in reservoir |
| Pneumatic system dew point &gt; -20°C at 7 bar causing condensate formation | 8 | Ice crystal abrasion in cylinder bore (Ra degradation from 0.4 to 1.6 μm in 500 cycles) | Desiccant dryer maintaining -40°C dew point with 3% purge flow and coalescing pre-filter |

## 5. Engineering Risks & FAQ
- **Caution**: 
- **Caution**: 
- **Caution**: 

### Q: How does a soft-close damper work?
**A**: A soft-close damper uses hydraulic or pneumatic pressure to slow the drawer's final closing motion, preventing slamming and reducing noise through controlled damping.

### Q: What materials are used in soft-close dampers?
**A**: Common materials include Polyoxymethylene (POM/Acetal) for the cylinder body, silicone oil as damping fluid, and stainless steel for components like pistons, ensuring durability and smooth operation.

### Q: Can soft-close dampers be installed in existing furniture?
**A**: Yes, many soft-close dampers are designed for retrofitting into existing drawer systems, typically requiring minimal modification and tools for installation.
