# Industrial Specification: Extrusion Die

## 1. Technical Definition
A precision tool that shapes molten aluminum into specific cross-sectional profiles during extrusion.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **15-45 MPa (2175-6525 psi) at 450-550°C**. Failure boundary: **Exceeds 55 MPa (7975 psi) at 600°C or falls below 10 MPa (1450 psi) at 400°C**, Mechanism: **Thermal fatigue from cyclic heating (450-550°C) and cooling (200-250°C) during extrusion cycles, combined with creep deformation at sustained temperatures above 500°C, leading to microcrack initiation and propagation in H13 tool steel**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Die land length-to-opening ratio exceeding 8:1 | 8 | Excessive back pressure causing material stagnation and weld line defects | Implement tapered die land design with progressive reduction from 10:1 to 4:1 ratio |
| Localized temperature gradient exceeding 100°C across die face | 8 | Thermal distortion creating profile deviation beyond ±0.1mm tolerance | Integrate multi-zone cartridge heaters with PID control maintaining ±5°C uniformity |

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

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

- **Caution**: 

### Q: What is the difference between H13 steel and tungsten carbide extrusion dies?
**A**: H13 hot work tool steel offers excellent toughness and thermal fatigue resistance for high-volume aluminum extrusion, while tungsten carbide provides superior wear resistance and longer lifespan for abrasive alloys or complex profiles, though at higher cost.

### Q: How does the die plate work with other BOM components like the backer plate?
**A**: The die plate shapes the aluminum profile, while the backer plate supports it against extrusion pressure. The bolster plate holds the assembly, and the bearing surface controls metal flow and surface finish—all working together for precise, consistent extrusion.

### Q: What maintenance is required for aluminum extrusion dies?
**A**: Regular cleaning to remove aluminum buildup, inspection for wear or cracks on the bearing surface, and proper storage to prevent corrosion. H13 dies may require periodic heat treatment, while tungsten carbide needs careful handling to avoid chipping.
