# Industrial Specification: Die Head

## 1. Technical Definition
The final shaping component in an extrusion system that determines the cross-sectional profile of extruded food products.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **15-45 MPa (150-450 bar) at 120-180°C**. Failure boundary: **Material yield strength threshold: 550 MPa for tool steel, 250 MPa for aluminum alloys**, Mechanism: **High-cycle fatigue failure due to cyclic thermal stress exceeding 300 MPa from 120°C to 180°C temperature differentials during extrusion cycles**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Material fatigue accumulation exceeding 10^6 cycles at 300 MPa stress amplitude | 8 | Crack propagation at die orifice leading to profile distortion &gt;0.1 mm tolerance | Implement finite element analysis-optimized fillet radii &gt;2.5 mm at stress concentration points |
| Food particle abrasion at velocities &gt;2 m/s with particle hardness &gt;3 Mohs | 8 | Orifice diameter wear exceeding 0.05 mm causing dimensional deviation | Apply plasma-enhanced chemical vapor deposition tungsten carbide coating with 1800 HV hardness |

## 3. Key Technical Parameters

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

### Q: What materials are best for food extrusion die heads?
**A**: Stainless steel (304 or 316) is ideal for food contact due to corrosion resistance and hygiene. Tool steel and hardened alloy steel offer durability for high-volume production.

### Q: How does the die head affect extruded food product quality?
**A**: The die head is the final shaping component that determines the cross-sectional profile, texture, and consistency of extruded foods. Precise engineering ensures uniform shape, minimal waste, and consistent product quality.

### Q: What maintenance is required for extrusion die heads?
**A**: Regular cleaning to prevent food residue buildup, inspection for wear on die plates/inserts, and ensuring heating/cooling jackets function properly. Proper maintenance extends lifespan and maintains product consistency.

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