Extruded aluminum cases are widely used across electronics, telecommunications, industrial control systems, battery packs, power supplies, and instrumentation equipment. Thanks to their excellent strength-to-weight ratio, corrosion resistance, and customizable designs, aluminum enclosures have become the preferred choice for manufacturers worldwide.
Whether you are looking for an extruded aluminum case, an aluminum extruded power case,Custom aluminum extruded case or an aluminium box section extrusion, understanding their manufacturing process, applications, cutting methods, and costs can help you choose the right solution for your project.
What Is an Aluminum Extruded Power Case?
An aluminum extruded power case is a protective enclosure manufactured from aluminum extrusion profiles. It is commonly used to house electrical components such as power supplies, battery systems, LED drivers, inverters, communication devices, and industrial electronics.
The extrusion process allows manufacturers to create complex cross-sectional designs with integrated slots, heat sinks, mounting channels, and assembly features. This makes aluminum extruded power cases both lightweight and highly functional.
Key Benefits

How Are Extruded Aluminum Cases Made?
The production of an extruded aluminum case involves several manufacturing stages.
Step 1: Aluminum Billet Preparation
High-quality aluminum alloys such as 6061, 6063, or 6082 are heated to the required extrusion temperature.
Step 2: Aluminum Extrusion
The heated billet is forced through a specially designed die under high pressure. This process creates the desired enclosure profile.
The profile may include:
- PCB slots
- Mounting grooves
- Heat sink fins
- Fastening channels
Step 3: Cooling and Straightening
After extrusion, the profile is cooled and straightened to ensure dimensional accuracy.
Step 4: Cutting
The extruded profile is cut into specified lengths according to customer requirements.
Step 5: CNC Machining
Additional operations may include:
- Drilling
- Milling
- Tapping
- Slot machining
- Engraving
Step 6: Surface Treatment
Popular finishes include:
- Anodizing
- Powder coating
- Sandblasting
- Brushing
- Electrophoresis
Step 7: Assembly
End plates, fasteners, handles, and accessories are installed to complete the finished aluminum extruded power case.
How to Cut Extruded Aluminum Case?
Proper cutting is essential to maintain dimensional accuracy and achieve clean edges.
Recommended Cutting Tools
Miter Saw
A carbide-tipped blade designed for non-ferrous metals provides excellent cutting quality.
CNC Saw
Ideal for high-volume production and precision cutting.
Band Saw
Suitable for thicker aluminum profiles and custom fabrication projects.
Cutting Tips
- Secure the profile firmly before cutting.
- Use sharp blades designed for aluminum.
- Apply steady feed rates.
- Remove burrs after cutting.
- Protect finished surfaces from scratches.
For custom enclosure manufacturing, CNC cutting is typically preferred because it ensures consistent dimensional accuracy.
How Much Does Aluminum Extruded Power Case Cost?
The cost of an aluminum extruded power case depends on several factors.
Material Grade
Common alloys include:
- 6063-T5
- 6063-T6
- 6061-T6
- 6082-T6
Higher-strength alloys generally cost more.
Profile Complexity
Enclosures with integrated heat sinks, mounting features, or complex internal structures require more sophisticated extrusion dies and manufacturing processes.
Surface Finish
Costs vary depending on the selected finish:
- Mill Finish
- Clear Anodized
- Black Anodized
- Powder Coated
- Custom Colors
CNC Machining Requirements
Additional machining operations increase production costs.
Order Quantity
Larger production volumes significantly reduce the unit cost.
Typical Price Range
| Product Type | Typical Cost Range |
|---|---|
| Standard Extruded Aluminum Case | USD 2– 20 per piece |
| Custom Aluminum Extruded Power Case | USD 5 – 80+ per piece |
| CNC-Machined Enclosure | USD 10 – 150+ per piece |
Actual pricing depends on dimensions, material specifications, machining complexity, surface treatment, and order quantity.
