# Industrial Specification: Casting Core

## 1. Technical Definition
Preformed insert that creates internal cavities in metal castings

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-1500°C (casting temperature), 0-100 MPa (mold clamping pressure)**. Failure boundary: **Thermal degradation at 1650°C (silica sand binder decomposition), mechanical failure at 120 MPa compressive stress**, Mechanism: **Thermal expansion mismatch between core material (CTE 12×10⁻⁶/K for silica sand) and solidified metal (CTE 23×10⁻⁶/K for aluminum) creates residual stresses exceeding core's 40 MPa tensile strength**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Insufficient binder curing at &lt;95% polymerization | 8 | Core disintegration during metal pouring | Infrared spectroscopy quality control with 98% polymerization threshold |
| Core positioning error &gt;±0.1 mm tolerance | 8 | Wall thickness deviation exceeding ±0.5 mm specification | Robotic placement with laser-guided alignment to ±0.05 mm accuracy |

## 3. Key Technical Parameters
| Parameter | Value | Unit | Status |
| :--- | :--- | :--- | :--- |
| tensile_strength | Config-dependent | MPa | Verified |
| thermal_stability | Config-dependent | °C | Verified |

## 4. System BOM & Knowledge Routing

### Industrial DNA Context (De-duplicated)
**Complementary Dependencies**: **Core Shooting Machine**, **Core Oven**, **Sand Mixer**  
**Downstream Applications**: Engine Blocks, Valve Bodies, Pump Housings  

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

### Q: What materials are used in casting cores?
**A**: Casting cores are primarily made from silica sand mixed with either resin or clay binders, and often feature a ceramic coating for improved surface finish and durability.

### Q: How do casting cores create internal cavities in metal castings?
**A**: Casting cores are preformed inserts placed in molds before metal pouring. The molten metal flows around them, and once solidified, the cores are removed, leaving precise internal cavities in the finished casting.

### Q: What specifications should I consider when selecting casting cores?
**A**: Key specifications include core weight (in kg), dimensional tolerance (in mm), and surface finish (Ra value). These ensure the core meets the required precision and quality for your specific foundry application.

## 6. Manufacturing Compliance
- ISO 8062:2020 (GEOMETRICAL PRODUCT SPECIFICATIONS FOR CASTINGS)
- EN 1559-1:2011 (FOUNDING - TECHNICAL CONDITIONS OF DELIVERY - PART 1: GENERAL)
