Custom K-Pop Light Sticks (OEM 3D Tooling & Injection Molding)

Premium 3D Diamond-Cut Engineering

Target Application: Elite Idol Branding & Limited Edition Merchandise.

The Challenge:

Premium idol brands require products that offer high-end aesthetics (luxury feel) rather than standard plastic finishes.

Complex shapes like diamond-cut facets often suffer from uneven light transmittance or internal shadows.

The Zhongda Solution:

Zhongda engineered custom 3D diamond-cut molds featuring anti-aliasing internal structures to maximize light refraction.

We utilized high-transmittance PS/PP polymers, optimizing the facet angles through optical simulations to ensure a brilliant, crystal-like glow.

The Result:

The superior "diamond" aesthetic allowed the label to position the item as a premium collectible with a higher retail price point.

Achieved consistent 100% client satisfaction, resulting in long-term manufacturing partnerships for subsequent tour legs.
