Trends in High-End Custom Cosmetic Empty Bottles: Innovations in Injection Molding, Printing, and Painting Technologies
With the continuous growth of the cosmetics market, injection molding, printing, and painting technologies for high-end custom empty bottles are undergoing comprehensive upgrades. In injection molding, electric injection molding machines and multi-material molding have become mainstream, achieving precision levels of 0.01mm while reducing energy consumption by 40%-60%, meeting demands for lightweight and complex structural designs. In-mold coating technology (such as polyurethane injection coatings) shortens the traditional three-day painting process to just five minutes, cutting paint waste by 90% while delivering scratch-resistant and corrosion-resistant properties.
Printing processes are advancing toward high-precision digital printing, supporting small-batch customization and complex curved-surface printing with a color gamut coverage of up to 98%, enhancing brand personalization. Meanwhile, eco-friendly painting technologies like UV-cured coatings and water-based paints are being widely adopted, offering paint film hardness exceeding 4H, along with excellent alcohol and scratch resistance, aligning with VOC emission reduction policies.
