# Industrial Specification: Precision Coating Dispenser

## 1. Technical Definition
A precision dispensing component that applies controlled amounts of release agents or coatings to mold surfaces

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-3.0 MPa (5-30 bar) at 20-60°C fluid temperature**. Failure boundary: **Fluid pressure exceeding 3.5 MPa (35 bar) causes diaphragm rupture, or fluid viscosity below 10 cP at 20°C causes seal leakage**, Mechanism: **Diaphragm material (typically PTFE or silicone) experiences plastic deformation beyond yield strength of 15-25 MPa at 3.5 MPa operating pressure, or low-viscosity fluid (&lt;10 cP) exceeds seal material's permeability coefficient of 1.2×10⁻¹² m²/s**.

### 2.1 Analytical Physics Model
Governed by the **Darcy-Weisbach Pressure Drop**:

> **Primary Equation**: $\Delta P = f \cdot \frac{L}{D} \cdot \frac{\rho v^2}{2}$  
> **Engineering Impact**: Critical for sizing CIP (Clean-In-Place) pump heads.
