wholesale private label eyeshadow palette

As the trend of personalized consumption in the beauty industry intensifies, customized eyeshadow boxes have become the core carrier of brand differentiation competition. According to data from 2025, the global customized eyeshadow box market size exceeded US$3.2 billion, with an annual growth rate of 18.7% (data source: Grand View Research). The process flow of customized eyeshadow boxes from design to mass production covers key links such as structural design, material selection, and surface treatment, providing technical reference for brands.

1. A complete analysis of the process flow of customized eyeshadow boxes

1. Demand analysis and design stage (time consumption accounts for 20%)

Market research: Determine the box type requirements through consumer portraits (age, skin type, usage scenarios), such as magnetic suction, folding or special-shaped structures.

3D modeling: Use Rhino or SolidWorks software to complete the box structure design. Key parameters include opening and closing angle (recommended 120°-150°), magnetic suction force (≥8N) and buckle tolerance (±0.2mm).

2. Material selection and pretreatment (time consumption accounts for 25%)

Substrate screening:

Environmentally friendly: PLA bioplastic (degradation cycle 6 months) or bamboo fiber composite material (cost is 15% higher than traditional ABS).

High-end: aluminum-magnesium alloy (surface anodized, hardness up to HV300) or acrylic (transmittance 92%).

Surface treatment:

UV coating: wear resistance increased by 3 times, passed the hundred grid test (ASTM D3359).

IMD process: pattern embedding is achieved, and the scratch resistance level reaches 4H (pencil hardness standard).

3. Mold development and injection molding (time consumption accounts for 30%)

Mold accuracy: mirror polished mold (Ra≤0.02μm) ensures seamless splicing of the box body, and the ejector design needs to avoid scratching the lining.

Injection molding parameters:

Temperature: ABS material needs to be controlled at 220-240℃.

Pressure: Holding time is positively correlated with product wall thickness (1mm wall thickness corresponds to 2 seconds of holding pressure).

4. Assembly and quality inspection (time consumption accounts for 25%)

Magnetic component installation: Servo press machine is used, and the mounting pressure error is ≤0.5N.

Functional test:

Opening and closing life test (≥100,000 cycles).

Drop test (1.5m height, 3 times on each of 6 sides without damage).

2. Technical difficulties and solutions

Technical challenges

Solutions

3. Future process trends

Intelligent manufacturing: 5-axis linkage machining center can shorten the mold development cycle by 40%.

Sustainable technology: Water-based ink printing technology reduces VOCs emissions by 90%, in compliance with EU REACH regulations.

Conclusion

The process flow of customized eyeshadow boxes needs to balance innovation and mass production feasibility. Flexible production is preferred, and a digital collaborative platform is established to shorten the delivery cycle.
