# Industrial Specification: Jointing System

## 1. Technical Definition
A mechanical assembly designed to securely connect and seal adjacent insulated panels.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-2.5 MPa clamping pressure, -40°C to +120°C temperature range**. Failure boundary: **Clamping pressure below 0.3 MPa causes seal separation, above 3.0 MPa causes gasket extrusion failure**, Mechanism: **Gasket material viscoelastic creep at sustained pressures exceeding yield strength (σ_y = 15 MPa for EPDM rubber), combined with thermal expansion mismatch (Δα = 23×10^-6 K^-1 between aluminum frame and polyurethane panel)**.

### 2.1 Analytical Physics Model
Governed by the **Frame Structural Deflection Analysis**:

> **Primary Equation**: $\delta = \frac{5 q L^4}{384 E I}$  
> **Engineering Impact**: Ensures structural stability for multi-stage machines.

| Symbol | Variable Definition | Localized Reference |
