# Industrial Specification: Folding Mechanism

## 1. Technical Definition
A mechanical assembly that precisely folds dough layers during the lamination process.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-2.5 MPa hydraulic pressure, 0.1-0.3 mm layer thickness tolerance, 15-45 cycles/minute**. Failure boundary: **Hydraulic pressure exceeding 3.2 MPa causes seal rupture, layer thickness below 0.08 mm causes tearing, folding force exceeding 850 N causes linkage deformation**, Mechanism: **Yield strength of AISI 304 stainless steel linkages (205 MPa) exceeded at 850 N folding force, causing plastic deformation; hydraulic seal failure occurs at 3.2 MPa due to elastomer compression set exceeding 25%**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Hydraulic fluid contamination exceeding ISO 4406 18/16/13 cleanliness level | 8 | Spool valve sticking causing asymmetric folding pressure | Install 3 μm absolute filtration with differential pressure monitoring at 0.15 MPa |
| Dough viscosity variation beyond 5000-15000 cP range | 8 | Layer thickness inconsistency exceeding ±0.05 mm tolerance | Implement real-time viscosity sensing with PID-controlled roller gap adjustment |
