Project Background
With the ongoing trend of high integration and modularization in new energy vehicle electrical systems, battery structural components play an increasingly critical role in vehicle platforms. As a key part for bearing, fixing, and protecting battery modules, the battery bracket requires high mechanical strength, dimensional stability, and environmental aging resistance, while meeting industry demands for lightweight design, cost reduction, and recyclability.

Product Structural Design Features
Load-bearing design: The overall structure adopts multiple X-shaped diagonal ribs + diamond grid stiffeners, achieving sufficient rigidity while reducing weight, especially suitable for large flat support areas.

Multi-function integration: Includes multiple positioning pins, bolt holes, and drainage channels to meet battery module mounting, electrical wiring routing, and water drainage requirements.

Snap-fit design: Embedded metal springs allow quick and secure assembly with the vehicle frame, improving assembly efficiency.

Protective edges: Raised ribs and closed corner guards enhance cushioning and protect the battery housing edges.

Material Formulation Advantages

Practical Application Advantages
1. Metal Replacement with Significant Weight Reduction
The density of PP-LGF40 is only 1.15–1.2 g/cm³, achieving over 30% weight reduction compared to traditional metal brackets (such as stamped steel), contributing to lower vehicle energy consumption and extended driving range.

2. Cost Reduction
Injection molding enables one-step forming, replacing multi-piece assemblies or metal welding structures, reducing mold count and assembly labor; raw material cost is also lower than engineering plastics like PA6 or PBT.

3. Adaptability to Harsh Environments
Suitable for humid, dusty, and frequently fluctuating temperature conditions in battery compartments; long-term resistance to corrosion, cracking, and loosening ensures battery pack safety.

4. Fast Customization Response
Our PP-LGF40 products support adjustable flow grades, customizable colors (black/gray/natural), and optional flame retardant or UV resistant functions, meeting diverse client design needs.

Typical Application Scenarios
Electric vehicle chassis battery trays and battery pack support bases

Battery module connection brackets and fixing clamps

Power battery module protective covers and impact cushions

Other in-compartment injection molded structural parts replacing metal components
