How To Improve The Surface Gloss of Eye Shadow Powder Pressed Copper Sheet Through Technology?

In the packaging of eye shadow products, powder pressed copper sheet not only carries eye shadow powder, but also directly affects the overall visual quality of the product. A copper sheet with full gloss and smooth surface can not only improve the product grade, but also enhance consumers' favorability towards the brand. In order to obtain the ideal gloss effect, material selection, surface treatment and precision technology must be controlled and innovated during the manufacturing process. The following five key processes can significantly improve the surface gloss of eye shadow powder pressed copper sheet, achieving a win-win situation of beauty and quality.

1. Choose high-purity copper materials to lay the foundation for gloss

The first step of high gloss effect comes from the material itself. Compared with ordinary industrial copper, high-purity copper has a finer grain structure and higher metal reflectivity, which provides a good foundation for subsequent polishing and plating processes. Using electrolytic copper or customized alloy copper materials with a purity of more than 99.9% not only makes the surface more uniform and has fewer impurities, but also effectively reduces the appearance of oxidation spots and small depressions, and improves the overall beauty of the final product. High-quality raw materials are an indispensable core condition for creating high-gloss copper sheets.

2. Precision polishing process to achieve mirror-level brightness effect

Polishing is a key step in determining the surface gloss of copper sheets. By combining multiple mechanical polishing with fine manual repair, the micro-textures and burrs on the surface of the material can be gradually eliminated to achieve a mirror-level reflection effect. High-end equipment such as centerless polishers, pneumatic grinders and wool wheel polishing technology can effectively control the polishing uniformity and surface flatness. In addition, choosing a polishing paste with the appropriate particle size will also affect the final brightness, achieving a customized effect of soft light or high light.

3. Electroplating and chemical plating technology to enhance gloss durability

To enhance the gloss and prevent the surface of copper from oxidizing and darkening, modern copper sheet manufacturing widely uses electroplating and chemical plating technology. Electroplating such as nickel plating and chrome plating can significantly improve the reflective effect and metal texture, while chemical plating can achieve a more uniform coating thickness, which is suitable for copper sheets with complex structures. In particular, the high-gloss coating formula can enhance the wear resistance and anti-fingerprint ability while improving the gloss, so that the copper sheet remains bright and new during powder pressing, transportation and use.

4. Optimize the surface coating process to improve visual brightness and texture

In addition to the gloss of the metal itself, the surface coating can also play a role in amplifying brightness and protective effects. Common coating methods include UV varnish, electrophoretic transparent coating, glossy PU paint, etc., which can not only give the copper sheet a high-gloss mirror vision, but also increase scratch resistance and anti-fingerprint functions. Some high-end products also use pearlescent paint or micro-light refractive coating to give the copper sheet a soft light or metallic iridescence, making the eyeshadow palette more visually layered and improving the overall texture.

5. Strictly control cleaning and anti-oxidation treatment to maintain long-term gloss and discoloration

Even if the initial gloss of the copper sheet is excellent, if the subsequent process or packaging link is not properly controlled, oxidation, discoloration or pollution may still occur, affecting the appearance of the finished product. Therefore, dust-free cleaning should be carried out immediately after polishing and electroplating, and anti-oxidation protection liquid should be sprayed or vacuum packaged. The entire production environment should also be kept dry and clean to prevent water vapor and sulfides in the air from corroding the copper surface. A sophisticated post-processing process is the key to ensuring that the copper sheet maintains its gloss for a long time during storage and use.

Conclusion

The surface gloss of the eyeshadow powder pressed copper sheet not only represents the product quality, but is also an important part of the brand image. From the selection of raw materials to precision polishing, electroplating coating, and then to post-protection treatment, every process detail determines the final visual performance of the copper sheet. By continuously optimizing and innovating these key links, not only can the product quality be steadily improved, but also it can stand out in the beauty market. In the future, as users pursue both packaging aesthetics and environmental durability, the surface gloss process of copper sheets will continue to move towards higher standards.
