# Industrial Specification: Capping Head

## 1. Technical Definition
A mechanical component that applies and seals caps onto containers within an industrial packaging system.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-2.5 kN axial force, 10-60 rpm rotational speed, 0.1-0.3 mm vertical tolerance**. Failure boundary: **Exceeds 3.0 kN axial force, exceeds 80 rpm rotational speed, exceeds 0.5 mm vertical misalignment**, Mechanism: **Yield strength of AISI 304 stainless steel (205 MPa) exceeded at 3.0 kN load, centrifugal force imbalance at &gt;80 rpm causing bearing fatigue, Hertzian contact stress exceeding 1.5 GPa at &gt;0.5 mm misalignment**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Cap diameter tolerance exceeds ±0.15 mm specification | 8 | Incomplete cap seating with 0.2-0.4 mm gap formation | Implement dual-laser diameter verification system with 0.02 mm resolution |
| Cap thread pitch deviation &gt;±5% from nominal 4.0 mm | 8 | Cross-threading causing 15-25 N·m torque spikes | Install torque-limiting clutch with 20 N·m threshold and automatic reversal |

## 3. Key Technical Parameters
| Parameter | Value | Unit | Status |

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

### Q: What materials are used in this capping head?
**A**: This capping head is constructed from durable stainless steel and hardened tool steel, ensuring longevity and resistance to wear in industrial environments.

### Q: How does the torque adjustment mechanism work?
**A**: The torque adjustment mechanism allows precise control over the sealing force applied to caps, preventing overtightening or under-tightening for consistent packaging quality.

### Q: What maintenance does this capping head require?
**A**: Regular cleaning of the chuck assembly and periodic lubrication of moving parts are recommended. The hardened tool steel components typically require minimal maintenance due to their durability.

## 6. Manufacturing Compliance
- ISO 9001:2015 - QUALITY MANAGEMENT SYSTEMS
