Advantages:
1. Competitive price.
2. Strict quality control system.
3. Quick mold making and delivery.
4. Advanced equipment, excellent R&D teams.
5. Professional technicians and rich experienced workers.
Rapid tooling
Fast and cost-effective process to create aluminum or steel injection molds for quick turn injection molding. Ideal for rapid prototyping needs or validating product concept for production.
Overmolding
Overmolding is a unique injection molding process that combines two or more components
together. It is the best practice for the plastic manufacturing of multi-color and multi-layers
products.
Insert molding
Insert molding is a custom injection molding process that encapsulates components in a plastic
part. It is most commonly used for prototype injection molding designs with threads and holes.
Liquid Silicone Rubber injection molding
Liquid silicone rubber (LSR) is a flexible prototype injection molding process that produces
elastic, durable parts. Get custom prototypes and production parts from 15 days.

FAQ
1. What is a Plastic Power Storage Empty Battery Case?
A Plastic Power Storage Empty Battery Case (often called a Battery Enclosure, Battery Housing, or Battery Box) is a custom-molded plastic shell designed to securely house and protect the internal components of a battery pack. This includes battery cells (Li-ion, LiFePO4, etc.), BMS (Battery Management System), wiring, and thermal management components. It provides electrical insulation, mechanical protection, thermal management structure, and often meets specific safety standards.
2. What types of battery cases do you manufacture?
We specialize in cases for a wide range of energy storage applications:
Consumer Electronics: For power tools, e-bikes/e-scooters, UPS backup systems, portable power stations.
Energy Storage Systems (ESS): For residential and commercial solar energy storage batteries.
Electric Vehicles (EV): Cases for electric motorcycle, scooter, and automotive auxiliary batteries (not primary traction packs).
Industrial Battery Packs: For medical equipment, telecom base stations, robotics.
Custom Shapes & Sizes: From small cylindrical cases to large, complex enclosures for modular battery systems.
3. What plastic materials are used?
Material selection is critical for safety (flame retardancy), durability, and performance:
ABS : Good impact resistance, rigidity, and surface finish. Common for consumer electronics. Available in FR (Flame Retardant) grades.
PC (Polycarbonate) / PC-ABS Blend: Excellent impact strength, transparency options (for viewing charge indicators), and good temperature resistance. Often UL94 V-0 rated.
PP (Polypropylene): Good chemical resistance and low cost. Used for less demanding applications.
PA (Nylon, e.g., PA66 with Glass Fiber): High strength, stiffness, and thermal resistance for structural parts or high-temperature environments.
Polyphenylene Sulfide or Specialty Compounds: For extreme heat or chemical resistance (e.g., near motor compartments).
4. What manufacturing processes do you use?
We employ advanced processes for quality and efficiency:
Injection Molding: Primary method for high-volume production. Ensures precision, repeatability, and excellent surface finish.
Structural Foam Molding: For larger cases, providing rigidity with lighter weight.
Overmolding / Two-Shot Molding: To create integrated seals, soft-grip areas, or multi-material parts in one cycle.
Ultrasonic Welding & Vibration Welding: For hermetically sealing two case halves together.
CNC Machining: For prototypes, low-volume batches, or complex features not feasible with molding.
5. How can I start a project?
To begin, please email us with:
3D CAD files of your battery case concept.
Target annual volume.
Key requirements: Material, color, UL rating, IP rating, etc.
We'll start with a free DFM analysis and project proposal.
6. Can you integrate features into the case design?
Yes, a key advantage of injection molding is part consolidation. We can integrate:
Mounting bosses, screw posts, and snap-fits for internal component mounting.
Baffles, ribs, and channels for structural rigidity, cell separation, and thermal management/airflow.
Cable ports, connector housings, and venting channels.
Living hinges for integrated battery covers.
EMI/RFI shielding features or coatings.
7. What is the production lead time after tooling?
First Shots (T1 Samples): 15-20 days after mold completion.
Mass Production: 30-45 days after sample approval, depending on quantity.
8. What about tooling (mold) investment and lead time?
Tooling Cost: Significant and varies based on case size, complexity, and cavitation. We provide detailed mold quotes.
Tooling Ownership: The customer owns the mold. We provide secure storage and maintenance.
Tooling Lead Time: Typically 45-60 days for a production-grade mold.
We recommend starting with CNC machined or 3D printed prototypes for form, fit, and function testing before mold commitment.
9. What is your MOQ (Minimum Order Quantity)?
Given the high tooling investment, MOQs for molded parts are substantial:
Injection Molded Cases: MOQ 10,000 pieces (lifetime) is typical to justify tooling.
CNC Machined Prototypes/Low Volume: MOQ 50-100 pieces.
For smaller quantities, shared molds or stock base models may be an option.
