Cosmetic bottle sandblasting is a type of glass cold processing method that provides a frosted finish to the glass surface, creating a more even light scatter when light passes through the cover. The principle of cosmetic glass bottle sandblasting involves using the impact of high-speed sand flow to clean and roughen the base surface. It is powered by compressed air to form a high-speed jet beam that rapidly喷射s the abrasive material onto the surface of the item to be treated, altering its surface appearance 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 the surface adhesion of the product, and boosts the frictional force of the contact surface. This enables the surface strengthening of the workpiece and various decorative treatments. Sandblasting is an ideal process for decorating and engraving glass products. Sandblasting on glass surfaces is categorized into two types: internal and external sandblasting.

Cosmetic Bottle Silk Screening: Some glass bottles go through this process as customers want certain patterns or logos printed on them. Silk screening comes in high-temperature and low-temperature versions, with high-temperature silk screening typically done before the cosmetic packaging stage. The silk screening room should be kept clean to prevent contaminants from the inks, ensuring a superior printing result. Cleaning, Inspection, and Packaging: The glass cosmetic bottles must pass an inspector's check to pass the quality control. Defective bottles are sorted out, some are discarded, and others can be reprocessed.
