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.

LED aluminum profiles, also known as LED aluminum extrusions or LED aluminum channels, are specially designed aluminum profiles that are used to house LED strips or LED tape lights. These profiles serve several purposes: Heat Dissipation: LED strips generate heat, and excessive heat can reduce the lifespan and efficiency of LEDs. Aluminum profiles act as heat sinks, dissipating heat away from the LED strips, thereby prolonging their lifespan and maintaining their brightness. Protection: The aluminum profile provides a protective housing for the LED strips, shielding them from dust, moisture, and physical damage. This helps to extend the lifespan of the LEDs and ensures consistent performance over time. Aesthetic Enhancement: LED aluminum profiles come in various shapes and designs, including flat, recessed, corner, and surface-mounted profiles. They can be installed discreetly to provide subtle accent lighting or used as architectural features to enhance the visual appeal of a space. Installation: The profiles typically feature channels or grooves where LED strips can be easily inserted and secured. They often come with mounting accessories for easy installation on various surfaces such as walls, ceilings, floors, or furniture. LED aluminum profiles are commonly used in residential, commercial, and industrial lighting applications, including under cabinet lighting, cove lighting, display lighting, signage, architectural lighting, and more. They offer a versatile and efficient solution for integrating LED lighting into various environments while providing functional and aesthetic benefits.
