Repeated glass bottle molding production leaves glass bottle molds with stubborn carbon deposits, oxide layers, residual glass stains and surface roughness defects. Regular blasting cleaning is an essential pretreatment procedure to restore mold surface smoothness, ensure glass bottle molding quality and extend mold service life. Ceramic beads is the ideal abrasive for glass bottle mold maintenance due to their perfect spherical shape, no dust and non-polluting properties, ceramic beads B40 being the most widely used sizes in this industry.

Ceramic Bead B40 features a medium and uniform particle size range of 0.250–0.425 mm, achieving an optimal balance between strong cleaning capacity and mild surface finishing. It can efficiently and thoroughly remove accumulated carbon dirt, aging oxide layers and residual glass burrs on mold surfaces without causing excessive cutting, pitting or deformation on precision mold surfaces. After treatment, the mold obtains a uniform fine satin texture with stable surface roughness, which effectively avoids defects such as bubbles, scratches and uneven gloss on finished glass bottles.

In addition, B40 ceramic beads boast excellent toughness and recyclability, featuring low dust generation and no iron contamination during the blasting process. They will not damage the mold base material or leave residual impurities, ensuring consistent and stable molding quality in mass glass production. Compared with traditional abrasives, B40 ceramic beads reduce mold wear, lower maintenance frequency and long-term production costs, making them the preferred blasting media for daily cleaning and regular maintenance of glass bottle molds.
