# Industrial Specification: Ejector Housing

## 1. Technical Definition
The structural enclosure that houses and protects the ejector mechanism in an ejection system.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-120 MPa internal pressure, -40°C to 180°C ambient temperature**. Failure boundary: **150 MPa yield strength (ASTM A36 steel), 200°C thermal deformation threshold**, Mechanism: **Von Mises stress exceeding 150 MPa causes plastic deformation; differential thermal expansion (α=11.5×10⁻⁶/°C for steel) exceeding 0.5 mm clearance induces binding**.

### 2.1 Analytical Physics Model
Governed by the **Thin-Wall Pressure Vessel Stress Analysis**:

> **Primary Equation**: $\sigma_h = \frac{P \cdot D}{2t}$  
> **Engineering Impact**: Determines the hoop stress boundary to prevent rupture.

| Symbol | Variable Definition | Localized Reference |
| :--- | :--- | :--- |
| P | Internal Pressure | Engineering Constant |
| D | Diameter | Engineering Constant |
| t | Wall Thickness | Engineering Constant |

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Hydraulic pressure surge exceeding 150 MPa | 8 | Housing wall fracture at stress concentration points | Integrate pressure relief valve set at 130 MPa with 10 ms response time |
| Cyclic thermal loading ΔT=100°C at 0.5 Hz frequency | 8 | Thermal fatigue cracking at weld joints (Coffin-Manson exponent n=0.3) | Implement Inconel 718 thermal barrier coating with 0.3 mm thickness |

## 3. Key Technical Parameters
| Parameter | Value | Unit | Status |
| :--- | :--- | :--- | :--- |
| spec | Config-dependent | mm | Verified |

## 4. System BOM & Knowledge Routing
### Core Components (Recursive Links)

### Industrial DNA Context (De-duplicated)
**Complementary Dependencies**: **Hydraulic Power Unit**, **Programmable Logic Controller (PLC)**, **Cooling System**  
**Downstream Applications**: Plastic Injection Molded Parts, Die Cast Metal Components, Rubber Molded Products  

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

### Q: What materials are used for ejector housings in machinery manufacturing?
**A**: Ejector housings are typically constructed from Tool Steel for high durability and wear resistance, or Aluminum Alloy for lightweight applications requiring corrosion resistance.

### Q: What are the key components in an ejector housing assembly?
**A**: Standard ejector housing assemblies include a Mounting Flange for secure installation, a Guide Bore for precise ejector alignment, and an Access Panel/Cover for maintenance access.

### Q: How does an ejector housing protect ejection systems?
**A**: The ejector housing provides structural enclosure that shields the ejector mechanism from environmental contaminants, mechanical damage, and ensures operational safety in machinery systems.

## 6. Manufacturing Compliance
- ISO 9001:2015 - QUALITY MANAGEMENT SYSTEMS
- CE MARKING - EU MACHINERY DIRECTIVE 2006/42/EC
