Glass Forming

BOC’s industrial gas-based flame polishing and surface & coating technologies are highly automated and consistent leading to high yields and low rejects. Flames from our special burners impinge the glass directly to remelt a thin surface layer. Polishing can be used to eliminate or reduce the need for etching, thus reducing the environmental impact and paving the way for a cleaner, safer working environment.

BOC’s products for glass polishing and mould coating are:

CARBOFLAM®

BOC’s CARBOFLAM® technology is a highly automated and reliable mould coating technology that uses the properties of industrial gas to coat a layer of carbon on to the glass product. The output is consistent, resulting in increased yield and reduced defects and rejects. The automated process reduces manual intervention and accidents.


Typical Customer Profile

  • Container manufacturers

  • Cosmetic manufacturers

  • Tableware glass product manufacturers


Key Customer Benefits

  • Improved surface qualities

HYDROPOX®

Our unique HYDROPOX® pre-mixed technology using oxygen and hydrogen is the solution of choice for high-end applications where speed and efficiency are critical. HYDROPOX is ideal for glass producers looking for high-quality surfaces, a brilliant finish and high yields. It is extremely popular among specialty, cosmetic and optical glass manufacturers, but is also suited to technical glass where it is used to anneal microcracks in the surface of the glass.

Technologies based on hydrogen and oxygen have been shown to increase efficiency compared with natural gas and oxygen or propane and oxygen mixtures. Although hydrogen is the preferred fuel, we also offer a variety of solutions and mixtures to suit individual needs:

  • HYDROPOX using a hydrogen/oxygen mixture is ideal for fire polishing thin glasses (1-2mm wall) in just 2 to 3 seconds. 

  • HYDROPOX-C using either a natural gas/oxygen mixture or a natural gas/hydrogen/oxygen mixture is recommended for fire polishing thicker glasses (2-5mm wall) in just 3 to 7 seconds.
