Product Summary
Our Custom Plastic Battery Pack Enclosure Mould is a professional precision solution for new energy battery enterprises, focusing on insulated, flame-retardant, and heat-dissipative customized battery pack casing molding. As a core Custom Plastic Injection Tooling and Precision Mold Design and Build product, it meets strict new energy industry requirements for casing protection, dimensional accuracy, and long-term safe use. Complementing our portfolio—including ABS Plastic Electrical Control Box Mould, Medical Patient Monitor Housing Plastic Mould, Custom Plastic PVC Pipe Cross Fitting, Heavy Duty Plastic Pallet Injection Mould, and Interlocking Plastic Hollow Block Wall Mould—it provides one-stop injection molding services to promote the safe and stable development of the new energy industry.
Product Overview
Specializing in precision injection molds and finished parts for new energy/energy storage customized plastic battery pack shells, our product serves new energy battery precision mold manufacturing and energy storage power battery supporting industries. Unlike small appliance molds such as Coffee Maker Plastic Housing Injection Mould or building material molds like Interlocking Plastic Hollow Block Wall Mould, this mold is engineered for battery protection scenarios, solving core pain points: high assembly precision, insulation flame retardancy, temperature resistance, and batch production consistency. We deliver a one-stop solution to enable mass production of high-quality battery pack enclosures, helping customers reduce costs and enhance competitiveness in the global new energy market.
Material Advantages
Our Custom Plastic Battery Pack Enclosure Mould boasts superior material advantages, tailored to the strict safety and performance requirements of new energy batteries, which is a core concern for global B2B purchasers. We adopt high-quality engineering plastics, including conventional flame-retardant PP, flame-retardant ABS, and PC/ABS alloy, all meeting battery safety standards with stable insulation performance and UL94 V-0 flame retardant level—ensuring automatic extinguishment in case of fire to eliminate safety hazards. The materials are low-smoke, low-toxic, free of harmful precipitation, and comply with environmental safety standards. For diverse scenarios, we offer customizable modified materials: glass fiber reinforced modification for enhanced rigidity, high-temperature resistance modification for adapting to battery charging/discharging heat, and low-temperature resistance modification for stable use at -40℃. Additionally, the mold uses P20HH pre-hardened mold steel (upgradable to S136 corrosion-resistant mirror steel for long-term mass production), ensuring corrosion resistance, dimensional stability, and long service life, perfectly matching the material performance of battery enclosures.
Product Features
Our molds stand out with new energy-specific advantages. High precision (±0.08mm installation hole tolerance, ±0.05mm shell fit tolerance) ensures precise battery module installation and tight shell fitting, suitable for automated assembly lines. Integrated heat dissipation ribs and installation columns eliminate secondary processing, improving assembly efficiency. The dense heat dissipation rib structure expands heat dissipation area, controls battery working temperature, and extends battery cycle life. Excellent temperature resistance (-40℃ to 85℃) prevents brittle cracking or deformation during temperature changes, while impact resistance and chemical corrosion resistance (against electrolyte leakage) ensure long-term safe use. Multi-cavity flow balance design ensures minimal batch size deviation and good interchangeability, reducing unit production costs.

We also support non-standard customization for other new energy battery casings, complementing our Medical Patient Monitor Housing Plastic Mould to expand new energy and medical equipment solutions.
Certifications and Compliance
Our molds and finished enclosures fully comply with new energy battery plastic shell quality and safety standards, including UL94 V-0 flame retardant certification. We have a dedicated quality control system covering raw material flame-retardant/insulation testing, 3D cavity inspection, first-piece assembly verification, and batch sampling. We also provide technical support for customers to complete battery product safety certification, ensuring seamless market access worldwide.
Customization Options
We offer flexible customization: size (100mm×80mm to 1500mm×800mm), battery type adaptation (square/soft-pack), material (conventional/flame-retardant/modified), surface texture (matte/high-gloss), and cavity design (1-in-1/1-in-2) based on production capacity and new energy project needs.
Production Process
Our strict process ensures precision: design (targeted enclosure design, CAE analysis, optimized ejection); machining (high-precision CNC, slow wire cutting, surface grinding); material treatment (two rounds of stress relief annealing, nitride hardening); quality control (full-process testing). We also provide 7-15 day rapid sample verification and lifelong maintenance.
