Key Product Features

1. Housing for DIY Power Bank Projects

This power bank case is intended for projects using 21700 battery cells. Its dimensions and internal layout should be assessed against the selected cells, circuit board, wiring, and other components.

For OEM projects, buyers can provide drawings or design files for dimensional review. This helps establish housing requirements before tooling and sample development.

2. Custom Plastic Injection Molding

WIN WIN provides plastic injection molding services for customized product housings. Available material options include ABS, PP, PS, PE, PVC, PA6, HDPE, and other materials subject to project requirements.

Material selection should consider mechanical strength, dimensional stability, operating temperature, surface appearance, and compatibility with the intended application. The final material grade should be confirmed during product development.

3. Flexible Surface Finishing

Available surface treatment options include polishing, texturing, painting, and other finishes subject to design feasibility.

These options help brands align the housing’s appearance with their product identity. Surface finish selection should account for the housing geometry, material, texture requirements, and production process.

4. Drawing-Based Dimensions and OEM Customization

The housing size is determined by the approved design or technical drawing. WIN WIN can review project requirements for customized dimensions, appearance, and manufacturing specifications.

Before mold production, buyers should confirm critical dimensions, component clearances, assembly interfaces, and sample acceptance criteria. These checks help reduce design discrepancies during manufacturing.
