# Industrial Specification: Mold Assembly / Fixture

## 1. Technical Definition
A specialized assembly or fixture used to hold and position molds during silicone molding processes.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.1-15 MPa clamping pressure, -20°C to 200°C thermal cycling**. Failure boundary: **Clamping pressure exceeding 18 MPa causes permanent deformation, thermal gradients &gt;220°C induce differential expansion exceeding 0.15% strain**, Mechanism: **Yield strength threshold of AISI 4140 steel (415 MPa) exceeded under combined thermal-mechanical loading, with coefficient of thermal expansion mismatch (11.7×10⁻⁶/°C steel vs 25×10⁻⁶/°C aluminum components) creating interfacial stresses**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Silicone flash accumulation at mold parting line exceeding 0.5 mm thickness | 8 | Clamping force distribution becomes non-uniform, causing mold deflection &gt;0.1 mm | Implement automated vision inspection with 0.05 mm resolution and robotic cleaning station at each cycle |
| Thermal cycling between 25°C and 180°C at &gt;5°C/min rate | 8 | Differential thermal expansion causes locating pin shear stress exceeding 250 MPa | Integrate controlled heating/cooling system with PID regulation maintaining ±2°C/min rate limit |
