Lekson Cosmetic Bottles Coating Factory, as a domestic enterprise specializing in cosmetic packaging surface treatment, focuses its core technology on the research and application of glass bottle baking paint and spraying processes. By integrating automated spraying production lines with an environmentally friendly paint system, the factory has formed a complete set of surface treatment solutions from standard bottle shapes to non-standard bottles, establishing a unique technological barrier in the cosmetic packaging niche market.
In glass bottle surface treatment, Leixin Factory employs a five-layer composite spraying technology: the base layer uses epoxy resin primer for enhanced adhesion, the middle three layers are gradient color coatings, and the surface layer is a food-grade UV curing paint. This process allows the product to exhibit pearl-like sheen while also ensuring compatibility with cosmetic contents through SGS certification. The Swiss JINMA automatic spray gun system on the production line achieves uniform spraying with a precision of 0.2mm, processing up to 3,000-5,000 standard bottle types per hour. Specifically for high-demand products like perfume bottles, the factory has developed a low-temperature curing process, reducing the traditional baking temperature from 180°C to 120°C. This ensures the paint film reaches a 3H pencil hardness standard while avoiding stress deformation of the glass substrate due to high temperatures.
Over the next five years, Raison plans to invest 120 million yuan in constructing a digital coating demonstration factory, integrating 5G and industrial internet technology for real-time process optimization. The digital twin system it is developing can simulate various environmental parameters to predict coating performance, potentially reducing the new product development cycle from the current 45 days to 20 days. As cosmetic packaging evolves towards personalization and functionality, this company focused on surface treatment technology is building an irreplaceable competitive advantage in the value chain through continuous innovation.
