# Industrial Specification: Heated Platens

## 1. Technical Definition
Heated metal plates that provide uniform thermal energy for vulcanizing rubber soles in molding presses.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **150-220°C with ±2°C uniformity across platen surface**. Failure boundary: **Thermal gradient exceeding 15°C/cm or surface temperature exceeding 250°C**, Mechanism: **Differential thermal expansion between Invar alloy heating elements (α=1.2×10⁻⁶/°C) and steel platen body (α=11×10⁻⁶/°C) causing stress exceeding yield strength of 345 MPa**.

### 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.
