As Senloong, specializing in sheet metal manufacturing, we provide high-performance and high safety customized lithium battery metal shell solutions for the new energy vehicle industry.
We strictly select high-strength aluminum alloy and high-quality galvanized steel plate as substrates, combined with advanced laser processing, robot welding, and digital forming processes to ensure that the products have excellent mechanical strength and consistency.
Through CAE simulation optimization of precision structural design, we have achieved a perfect balance between lightweight and safety protection.
Ultimately, we ensure that each set of battery enclosures can provide stable and reliable operational support and safety protection for battery modules in extreme environments such as vibration, temperature differences, and humidity.

Core features (for empty battery box structure)
▲Modular architecture design
Support mainstream standardized battery module (square shell/soft pack/cylindrical) plug and play installation
The internal bracket can flexibly adapt to different battery cell brands and arrangements
Provide a split type box structure (side panel, bottom panel, end cover independent module) for easy assembly, maintenance, and replacement of production line segments
▲Strengthen the security protection structure
Adopting a cage style anti-collision frame with interwoven longitudinal and transverse beams, and setting up buffering and energy absorbing structures in key collision areas
Optional double-layer composite bottom plate (outer protective plate+inner support plate) to enhance the bottom's impact resistance and puncture resistance
Pre set standardized explosion-proof relief valve installation position, supporting multi-channel directional relief design
Internal full area insulation treatment (insulation coating/insulation gasket integrated groove) to eliminate the risk of leakage
▲Balancing lightweight and high strength
Using high-strength lightweight aluminum alloy or aluminum magnesium alloy as the main body, composite material reinforcement can be selected for key stress areas locally
Design of reinforcement network based on CAE topology optimization to achieve optimal matching between material distribution and mechanical properties
Scientifically layout weight reducing holes and hollow structures, while ensuring overall rigidity and vibration safety, to achieve a weight reduction of 15-25% for the box body
▲High precision manufacturing and adaptability
Fully CNC machining ensures that the flatness of the battery cell installation surface is ≤ 0.5mm, and the accuracy of the module positioning hole is ± 0.1mm
Reserved standardized interfaces to support customers' convenient integration of BMS, thermal management pipelines, and high and low pressure connectors
The surface conductive/insulating coating can be customized and supports customer secondary spraying and brand identification processing

FAQ
Q1: What is the minimum order quantity (MOQ)?
A: The standardized box MOQ is 50 sets; The MOQ for the new customized development project is 200 sets; Small batch R&D orders can be accepted, but a one-time mold opening fee will be charged.
Q2: Do you provide anti-corrosion and insulation treatment?
A: Standard configuration: The aluminum alloy box is made of conductive oxidation, and the steel plate box is galvanized and powder coated. Optional: Internal insulation coating (withstand voltage 1000V), bottom armor coating, fireproof coating, etc.
Q3: How to ensure batch consistency?
A: We adopt a system of "first piece full inspection+patrol inspection+last piece confirmation", retaining sample pieces for each batch and using the same set of molds and fixtures to ensure that the difference between batches is less than 0.2mm.
Q4: Does it support customers to provide materials themselves?
A: Support. We accept aluminum/steel plates of specified brands and specifications from customers for processing, and only charge processing fees. Materials and supporting documents need to be provided in advance.
Q5: How long does the customized development cycle take?
A: The standard development process is: scheme confirmation (5 days) → mold making (15 days) → sample trial production (10 days) → mass production. The delivery cycle for the first set of samples is approximately 30 working days.
