The manufacturing of extruded aluminum battery housings is a multi-stage process that transforms aluminum alloy billets into strong, lightweight, and precisely formed enclosures. This method is favored for creating long, robust profiles with a constant cross-section, ideal for battery packs in various applications.

1
Billet Preparation & Heating

The process begins with cylindrical logs of a specific aluminum alloy (commonly from the 6000 series, like 6061 or 6063, for their good strength and extrudability). These billets are pre-heated in a furnace to a precise temperature (typically between 400 - 500°C). This thermal treatment softens the metal, making it pliable enough for extrusion without melting it.

2
The Extrusion Process

The heated billet is loaded into the extrusion press. A hydraulic ram applies immense pressure, forcing the softened aluminum through a precision-engineered steel die. The die's opening defines the housing's final cross-sectional profile, including its external walls, internal ribs for structural support, and channels for thermal management or cable routing. The emerging profile is a continuous length of the shaped aluminum.

3
Quenching & Stretching

As the profile exits the die, it is rapidly cooled using air or water quenching. This "freezes" the profile's shape and initiates the strengthening process. The long, straight profile is then mechanically stretched. This critical step corrects any twisting or dimensional irregularities and aligns the metal's grain structure.

4
Aging & Cutting to Length

The profiles undergo artificial aging (precipitation hardening) in an oven. This heat treatment allows the alloy's microstructure to fully develop, bringing the aluminum to its specified temper (e.g., T5 or T6) and achieving its final mechanical strength and hardness. The hardened profiles are then cut to the precise required lengths for individual battery housings.

Frequently Asked Questions
What aluminum alloys are used for battery case profiles, and why?
We primarily use 6061, 6063, and 6060 aluminum alloys. These 6000-series alloys offer an excellent balance of strength, corrosion resistance, and extrudability, making them ideal for battery enclosures that must withstand mechanical stress and environmental exposure in e-bikes and electric scooters.
What surface treatment options are available for the battery housing profiles?
We offer a wide range of surface treatments including mill finish, powder coating, anodizing, electrophoresis, fluorocarbon coating, and wood grain finishes. Custom colors are also available based on your specific requirements.
What is the minimum order quantity (MOQ) and typical lead time?
The minimum order quantity is 500 kg. For die development and sample testing, the lead time is approximately 7 - 10 days. Mass production is typically completed within 15 - 30 days depending on order volume and complexity.
Can the aluminum battery profiles be customized in terms of size, shape, and color?
Yes, full customization is available. Profile cross-sections, wall thickness (0.8 - 5.0 mm), length (standard 6 m or custom), color, and surface finish can all be tailored to your design specifications. We also offer value-added services including drilling, milling, cutting, welding, bending, assembling, and CNC machining.
What post-extrusion processes are applied to ensure the strength and precision of the profiles?
After extrusion, profiles undergo quenching (rapid cooling) to freeze the shape, followed by mechanical stretching to correct dimensional irregularities. Artificial aging (precipitation hardening) is then applied to achieve the specified temper - T5 or T6 - ensuring optimal mechanical strength and hardness for demanding battery housing applications.
Are these aluminum battery enclosures suitable for outdoor and all-weather use?
Absolutely. The corrosion-resistant surface treatments and high-grade aluminum alloys ensure the enclosures perform reliably in diverse weather conditions, including rain, humidity, and temperature fluctuations. They are well-suited for urban commuter e-bikes, e-scooters, and other outdoor recreational electric mobility products.
