The materials of electroplated cosmetic shells are diverse, and choosing the appropriate substrate is the key to ensuring the quality of the final product. The following are several commonly used electroplating substrates and their characteristics, suitable for different needs of cosmetic packaging:

1. * * Metal**
-Zinc alloy: economical, easy to process and shape, widely used in various cosmetic bottle caps, powder boxes and other components.
-* * Aluminum * *: lightweight and with good ductility, suitable for making thin-walled containers, such as lipstick tubes, eye shadow discs, etc.
-Stainless steel: corrosion-resistant, high strength, commonly used in high-end makeup brushes and beauty instrument casings, showcasing a sense of quality.
   
2. * * Plastic**
-ABS resin: Low cost, easy to dye, convenient for secondary processing, suitable for large-scale production.
-PC/ABS alloy: It combines toughness and rigidity, has good heat resistance, and is suitable as one of the electroplating substrates.
-Polycarbonate (PC): High transparency and strong impact resistance, commonly used in packaging designs that require transparency.
   
3. * * Other synthetic materials**
-Electroplating grade nylon: specially developed for electroplating to ensure good adhesion and aesthetic effect.
-Electroplating grade PETG: Transparent, non-toxic, environmentally friendly, suitable for packaging that comes into direct contact with cosmetics.

4. * * Composite materials**
Combining the characteristics of two or more materials, such as metal plastic composite structures, can not only enjoy the texture of metal, but also reduce weight and expand design freedom.

The choice of material depends on the specific purpose of the cosmetic, budget constraints, and design style. Each type of material has its unique advantages, and the key lies in matching the product's positioning with market demand. Manufacturers should fully consider cost, quality, and user experience to make the most suitable choice.
