- CARBOFLAM – Mould coating for press and blow forming processes
One area of glass production that offers vast scope for efficiency gains is the surface coating of moulding tools with carbon. Compared with alternative methods for surface coating (manual lubrication, spraying and insulating with graphite suspensions, waxes, emulsions etc.), the application of carbon offers numerous advantages.
Our CARBOFLAM solution is a versatile process that can be applied to all types of glass. It is the most effective surface coating technique because it makes use of the material-specific release and insulating properties of pure carbon. These include an even temperature level during mechanical glass forming.
Highlights at a glance
- - Higher productivity due to improved process stability and longer application time of the moulding tools
- - Higher glass quality through elimination/minimisation of structural marks from the moulding tools on the glass surfaces
- - New products due to improved glass distribution thanks to higher mould temperatures
- - Lower maintenance costs through process optimisation
- - Substantial reduction in workplace pollution compared with other applications (e. g. cracking applications)

Protective atmosphere for your tin bath
Gases play an important role in the forming of float glass, where a nitrogen/hydrogen atmosphere is used to avoid oxidation of the glass tin and minimise the tin count in the glass. The success of forming hinges on consistent delivery of your selected ratio and volume flow (e.g. 95% N2 / 5% H2) and on a secure supply of high-purity gases (N2 5.0 and H2 3.0).
The float glass forming process also relies on sulfur dioxide. This is injected near the transitional roll desk to improve the physical, chemical and mechanical properties of the glass surface and extend the life of the rollers.
We can help ensure the success of your float glass production line with reliable supplies of nitrogen and hydrogen in the required purity levels, complementing this with cost-effective, safe and reliable flow control equipment for optimum results. Depending on your volume requirements, we can supply these gases in bulk or install an ECOVAR® on-site supply system.
Mould coating for press and blow forming processes
Industrial gases are also used in the forming of art, tableware and container glass, enhancing press and blow forming processes, for instance. Our CARBOFLAM® solution helps to optimise forming for these glass types.
