# Industrial Specification: Twin-Screw Polymer Compounding Extruder

## 1. Technical Definition
Industrial machine for melting, mixing, and homogenizing plastic compounds with additives

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **15-300 bar melt pressure, 50-400°C barrel temperature, 100-1200 RPM screw speed**. Failure boundary: **Melt pressure exceeding 350 bar causes barrel rupture, screw speed exceeding 1300 RPM induces polymer degradation, barrel temperature exceeding 450°C initiates thermal decomposition**, Mechanism: **Exceeding yield strength of barrel steel (typically 550 MPa for 4140 steel) at high pressure, shear-induced polymer chain scission at excessive screw speed, Arrhenius kinetics of polymer degradation at elevated temperatures**.

### 2.1 Analytical Physics Model
Governed by the **L10 Bearing Life & Fatigue Model**:

> **Primary Equation**: $L_{10} = (\frac{C}{P})^p$  
> **Engineering Impact**: Predicts mechanical lifecycle before component fatigue.
