# Industrial Specification: Polymer Extrusion Die Plate

## 1. Technical Definition
Precision-machined plate that shapes molten plastic into specific profiles during extrusion.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **15-45 MPa pressure, 180-280°C temperature, 0.1-2.0 mm/s extrusion velocity**. Failure boundary: **Yield strength exceedance at 310 MPa (AISI 4140 steel), thermal expansion differential &gt;0.15 mm/m at 300°C, surface roughness degradation beyond Ra 0.4 μm**, Mechanism: **Thermal-mechanical fatigue from cyclic heating (ΔT=120°C) causing microcrack initiation at stress concentrations (Kt=2.8), polymer degradation products (carbon black accumulation) accelerating abrasive wear via three-body mechanism**.

### 2.1 Analytical Physics Model
Governed by the **LMTD Logarithmic Mean Temperature Difference**:

> **Primary Equation**: $Q = U \cdot A \cdot \Delta T_{lm}$  
> **Engineering Impact**: Sizing validation for pasteurization and cooling tunnels.

| Symbol | Variable Definition | Localized Reference |

- **Caution**: 

### Q: What materials are best for polymer extrusion die plates?
**A**: Tool steel offers durability for high-volume production, stainless steel provides corrosion resistance, and hardened aluminum is lightweight with good thermal conductivity for specific applications.

### Q: How do thermal equalization channels improve extrusion die performance?
**A**: Thermal equalization channels distribute heat evenly across the die plate, preventing material flow inconsistencies and ensuring uniform plastic profile dimensions during continuous extrusion.

### Q: What specifications should I consider when selecting an extrusion die plate?
**A**: Key specifications include operating temperature range, orifice diameter for your profile, plate thickness for structural integrity, pressure rating for your extrusion system, and surface hardness for wear resistance.

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