SUBLIMATION is a chemical-physical phenomenon which consists in the passage of the state of a substance directly from the solid phase to the gas one, without passing through the liquid state.
The sublimation process, applied to the decoration of aluminum and steel profiles and sheets, consists of an additional processing to the traditional painting process.
The process can reproducing the wood, marble and other decorations on metallic pre-painted sufaces.
The designs are printed on special films with sublimation inks.

Our systems are patented (Italian,European and worldwide patent) Stillwood® (which we are licensees) is the most advanced technology available on the market.
Each plant is equipped with bagging machine and oven. The bagging machine using the sublimation film to create a tubular sheath around the profiles.
The wrapped profiles are then hooked to specific depression sockets of the sublimation oven where, due to the combined action of depression and heat, the wood or marble design(imprinted on the sublimation film) are transferred into the paint thickness.

At the end of the cycle, the film envelopes, are removed and the material is ready for packaging.
