Cosmetic bottle sandblasting is a type of glass cold processing method that creates a frosted finish on the glass surface, resulting in a more uniform scattering of light through the lampshade. The principle of cosmetic glass bottle sandblasting involves using high-speed sand streams to clean and roughen the base surface. Compressed air is used as the power source to form a high-speed jet stream, which then rapidly sprays the material onto the surface of the workpiece, altering its outer surface or shape.

Due to the abrasive impact and cutting action on the workpiece surface, it achieves a certain level of cleanliness and varying roughness, thereby improving the surface properties of the workpiece. This enhances the fatigue resistance of the workpiece, increases surface adhesion, and boosts frictional force on the contact surface. It enables the surface hardening and various decorative treatments of the workpiece. Sandblasting is an ideal process for decorating and engraving glass products. Sandblasting on glass surfaces is divided into two types: internal and external sandblasting.

Cosmetic Bottle Silk Screening: Some glass bottles undergo this process because the client wants certain patterns or their company logo printed on them. There are high-temperature and low-temperature silk screening methods, with high-temperature silk screening typically done before the cosmetic packaging bottle stage. The silk screening room should be relatively clean to prevent impurities from contaminating the inks, resulting in a better final effect. Cleaning, Inspection, and Packaging: The glass cosmetic bottles must pass an inspector's check to be approved. Defective bottles are selected out, some are discarded, and others can be reprocessed.
