Manufactured from high-grade 6000-series aluminum extrusions and precision-cut sheet, the upper base assembly is engineered to hold battery modules securely from above, distribute vertical and lateral loads, and provide fixed mounting points for busbars, wiring harnesses, and thermal management components. Depending on the pack architecture, it may also function as a compression plate or a rigid tie-bar across the top of the module stack. All components are joined via robotic welding or structural fasteners, then CNC-machined as a complete assembly to guarantee hole-pattern accuracy and flatness across the entire unit.
Shengxin delivers this assembly fully inspected and, if specified, surface-finished — anodized or powder coated — so it arrives at your production line ready for immediate integration. Our aluminum battery structural component capabilities cover the full value chain: from extrusion die design and profile production to welding, machining, and surface treatment under one roof.

In a typical EV battery pack, structural components are layered. This diagram shows conceptually how the Battery Upper Base Assy interfaces with other pack elements — and which Shengxin products can support each layer.
| Layer | Component | Related Shengxin Product |
|---|---|---|
| Top Cover / Lid | Sealed enclosure lid | Custom aluminum sheet fabrication |
| Upper Support (this product) | Battery Upper Base Assy | Current page |
| Module Retention | Side plates, module frames | Aluminum Battery Side Plate (custom) |
| Main Enclosure / Tray | Battery tray, front & rear bases | Aluminum Battery Trays, Battery Frontal Base, Battery Rear Base |
By sourcing the Upper Base Assy alongside your tray and lower structural components from Shengxin, you ensure consistent material lot traceability, aligned tolerances, and a simplified supplier interface — all from one vertically integrated partner.

Assemblies demand more than just good components — they demand integrated manufacturing discipline. Shengxin’s 29-year track record in aluminum extrusion and fabrication provides the process control needed to deliver complex welded assemblies with repeatable quality.
Extrusion, welding, machining, and finishing all happen within Shengxin’s facility — no subcontractor hand-offs, one quality system, one point of contact.
We design and build dedicated welding and machining fixtures for your upper base assembly, ensuring every unit meets dimensional specifications without variation drift.
From a single prototype to multi-thousand-unit production runs, our 35 extrusion lines and 5 container loading platforms scale with your program.
Compliance with GB5237, Qualanod, BS3987, JIS H8601, EN755, EN12020. We support PPAP submission with full dimensional reports and material certs.
Global Shipping Expertise: We export to 97 countries, with custom packaging designed to protect large welded assemblies during transit. All shipments are container-optimized from our 5,000-ton warehouse with dedicated loading bays.
A: It typically includes longitudinal rails, crossmembers, mounting brackets, and integrated fasteners or threaded holes — all welded or assembled into a single part number. The exact content is defined by your design; we work directly from your BOM and drawings.
A: Yes. Helicoils, PEM-style inserts, studs, or pressed-in nuts can be installed during production, so the assembly arrives ready to bolt onto your pack without additional operations.
A: We strongly recommend manufacturing the main battery tray and the upper base assembly within the same supply chain. Shengxin can produce both, using a common datum strategy and matched machining fixtures, guaranteeing alignment of all mounting interfaces.
A: While the upper base is not typically a sealed component, we can provide CMM reports, 3D scanning data, and if required, coordinate with leak-test requirements for the complete pack enclosure when we supply the full set of structural parts.
A: We support iterative prototyping. Our engineering team manages revision control closely, and our in-house die shop and machining capability allow us to turn revised components quickly — typically within 2–3 weeks for a modified upper base assembly prototype.

An aluminium profile is a versatile structural component made from aluminum. It is created by extruding aluminum through a shaped die to form a specific cross-sectional profile. These profiles are widely used in various industries due to aluminum's lightweight, strength, and corrosion resistance. Here are some key points about aluminium profiles: Manufacturing Process: Aluminium profiles are produced through a process called extrusion, where aluminum billets are heated and forced through a die to create long pieces with a consistent cross-sectional shape. Shapes and Sizes: Aluminium profiles come in a variety of shapes and sizes, including T-slots, channels, angles, tubes, and custom designs to meet specific requirements. Applications: They are used in a wide range of applications, including construction (window and door frames, curtain walls), transportation (automotive parts, aerospace components), industrial machinery (frameworks, conveyors), and consumer goods (furniture, electronics). Advantages: Lightweight: Aluminium is much lighter than steel, making it easier to handle and transport. Strength: Despite its low weight, aluminium has a high strength-to-weight ratio. Corrosion Resistance: Aluminium naturally forms a protective oxide layer, which enhances its resistance to corrosion. Versatility: The ability to extrude aluminium into complex shapes allows for a wide range of design possibilities. Recyclability: Aluminium is highly recyclable, which makes it an environmentally friendly material choice. Surface Treatments: Aluminium profiles can undergo various surface treatments such as anodizing, painting, or powder coating to enhance their appearance, durability, and resistance to wear and corrosion. Overall, aluminium profiles are essential components in many modern industries, providing a combination of flexibility, durability, and efficiency.

Aluminium extrusion profiles .
Anodizing is an electrochemical process that converts the surface of aluminum into a durable, corrosion-resistant oxide layer. The silver anodizing process gives aluminum profiles a sleek, metallic finish while enhancing their protective qualities. This treatment also makes the profiles more resistant to scratches, fading, and environmental damage. T-slot aluminum extrusion profiles are a type of modular framing system commonly used in various applications such as manufacturing, automation, robotics, and DIY projects.
We deliver high-volume, specification-compliant aluminum tube bending for global distributors and major construction projects. Ensure supply chain reliability with our certified manufacturing and logistics support.
