How To Improve The Durability of Eye Shadow Powder Pressed Copper Sheets Through Innovative Production Processes?

In the packaging structure of eye shadow products, powder pressed copper sheets are the basic materials that directly carry eye shadow powder. Their durability not only affects the product experience, but also affects the quality stability of the entire eye shadow tray. As the beauty industry continues to increase its requirements for environmental protection, efficient production and user experience, the shortcomings of traditional copper sheets in terms of pressure resistance, deformation resistance and corrosion resistance have gradually emerged. Therefore, manufacturers have optimized the performance of copper sheets through innovative production processes. The following five aspects will show how to comprehensively improve the durability of eye shadow powder pressed copper sheets through technological upgrades.

1. Select high-ductility copper materials to lay the foundation for the durability of the pressed plate

High-quality raw materials are the primary prerequisite for improving product performance. High-ductility copper materials can better maintain a flat shape and reduce fractures, bending and other phenomena when undergoing complex processes such as stamping and pressing. Compared with ordinary industrial copper, some customized alloy coppers have better flexibility and pressure resistance, and are easier to subsequently surface treat. Manufacturers can cooperate with upstream raw material suppliers to control the composition ratio and thickness standards of copper materials from the source, laying a solid foundation for sheet pressing.

2. Precision stamping technology to improve the deformation resistance of copper sheets

During the copper sheet forming process, traditional stamping is prone to edge burrs and uneven thickness, affecting the consistency and pressure resistance of the finished product. By adopting high-precision molds and multiple stamping processes, the dimensional error and structural strength of each copper sheet can be effectively controlled. At the same time, cold pressing technology combined with CNC equipment can greatly reduce stress concentration areas, thereby reducing the probability of deformation during powder pressing or transportation. This type of innovative stamping technology is becoming an important standard for high-end cosmetic packaging.

3. Surface treatment innovation to enhance corrosion and oxidation resistance

Eye shadow products are often exposed to humid, high temperature or chemical environments. Untreated copper sheets are very easy to oxidize and discolor, affecting appearance and safety. Today's surface treatment technology has gradually developed from traditional nickel plating and tin plating to new protection methods such as nano coating and electrophoretic coating. These innovative treatments not only improve the corrosion resistance of the copper sheet, but also enhance the adhesion and color stability of the powder, effectively extending the service life and shelf life of the product.

4. Upgrade the powder pressing process to avoid the warping and deformation of the copper sheet during the powder pressing process

The powder pressing link is a key step that affects the deformation of the copper sheet. The traditional single high-pressure powder pressing easily causes instantaneous stress concentration on the copper sheet, resulting in local bulging or warping. Improvement solutions such as: using multiple low-pressure progressive powder pressing and combining vibration distribution technology can more evenly distribute and compact the eye shadow powder, thereby reducing the uneven force on the copper sheet. At the same time, the use of a buffer layer lined with a powder pressing mold can also help reduce the impact force, significantly reducing the deformation rate of the copper sheet during processing.

5. Integrate an automated detection system to improve the consistency and stability of each copper sheet

Maintaining product stability during mass production is inseparable from an efficient detection process. By introducing a visual recognition system, an automatic thickness measurement device, and a flatness detection device, real-time screening of each copper sheet can be achieved, and defective products can be removed in a timely manner. Advanced MES production systems can also track and analyze data from each process, achieving traceability management from raw materials to finished products. Such automation and digital upgrades have greatly improved the consistency and reliability of the entire batch of copper sheets.

Conclusion

In the fiercely competitive beauty packaging market, the durability of eyeshadow powder pressed copper sheets is not only related to product quality, but also reflects the professional level of manufacturing technology. From material selection to process upgrades, to the introduction of intelligent detection systems, the optimization of each link will directly affect the end-user experience. In the future, only by continuously promoting technological innovation and refined process management can we truly meet the market's demand for high-quality, beautiful and long-lasting eyeshadow packaging accessories.
