# Industrial Specification: Metal Casting Mold Core

## 1. Technical Definition
Removable insert for creating internal cavities in metal casting molds

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-850°C, 0-150 MPa compressive stress, 0.1-10 μm surface roughness**. Failure boundary: **Thermal fatigue cracking at 900°C differential, compressive yield at 180 MPa, dimensional distortion beyond ±0.05 mm tolerance**, Mechanism: **Thermal expansion mismatch (α=12×10⁻⁶/K for H13 steel vs α=23×10⁻⁶/K for aluminum), cyclic plastic deformation at 0.2% strain amplitude, creep deformation at 0.0001%/hour above 700°C**.

### 2.1 Analytical Physics Model
Governed by the **Heat Sterilization F0 Lethality Model**:

> **Primary Equation**: $F_0 = \int_{0}^{t} 10^{(T-121.1)/z} dt$  
> **Engineering Impact**: Validates microbial reduction integrity for aseptic packaging.

| Symbol | Variable Definition | Localized Reference |
| :--- | :--- | :--- |
| T | Process Temp (°C) | **$T \in [0-850°C]$ °C** (Per `temperature_range`) |
| t | Exposure Time (min) | Engineering Constant |
| z | Z-value | **10 °C** (Standard for *C. botulinum*) |

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Incomplete binder pyrolysis at 200-400°C | 8 | Gas evolution causing blowholes and porosity in castings | Controlled thermal decomposition with 2°C/minute ramp rate to 600°C |
| Silica sand phase transformation at 573°C (α→β quartz) | 8 | Sudden 0.45% volume expansion causing mold cracking | Zircon sand substitution (ZrSiO₄ stable to 1670°C) |

## 3. Key Technical Parameters
| Parameter | Value | Unit | Status |

### Industrial DNA Context (De-duplicated)
**Complementary Dependencies**: **Induction Melting Furnace**, **Sand Molding Machine**, **Shot Blasting Machine**  
**Downstream Applications**: Engine Blocks, Pipe Fittings, Gear Housings  

## 5. Engineering Risks & FAQ
- **Caution**: 
- **Caution**: 
- **Caution**: 

### Q: What materials are best for high-temperature metal casting applications?
**A**: For high-temperature applications, tool steel and ceramic composite cores offer excellent thermal resistance and durability, with ceramic composites providing superior heat insulation for complex castings.

### Q: How do venting channels in mold cores prevent casting defects?
**A**: Venting channels allow gases to escape during the metal pouring process, preventing air pockets, porosity, and incomplete filling that can compromise casting quality and structural integrity.

### Q: What factors determine the optimal surface finish (Ra) for a casting mold core?
**A**: The required Ra depends on the casting metal type, desired final product surface quality, and ease of core extraction. Smoother finishes reduce friction during removal but may require specific material treatments.

## 6. Manufacturing Compliance
- ISO 8062:2020 (DIMENSIONAL AND GEOMETRICAL TOLERANCES FOR CASTINGS)
- DIN EN 1563:2018 (FOUNDING - SPHEROIDAL GRAPHITE CAST IRON)
