Across the world, all De Dietrich plants apply
the same quality of glass, the production of which being centralised in France. This is the guarantee for you to transfer instantaneously all process parameters from one De Dietrich equipment to another, whatever the size or the origin, without any test or validation.
During the preparation of each batch of DD 3009 glass, numerous tests and controls assure us of a perfect and reproducible quality, suppressing any risks of production defect.

The glass-lining process itself consists in spraying like a paint a suspension of glass powder on the surfaces to be glass-lined ; after drying, the parts are fired into furnaces at temperatures that affect fusion between glass particles, the result after cooling being an impervious, smooth fire polished coating of glass. This cycle of spraying, drying, firing is repeated layer after layer until obtaining the required thickness, each coat being submitted to various quality controls : thickness, spark testing at 20 kV, visual inspection…
