Abstract
The invention relates to a method including very superficial embossing combined with superficial laminating, which involves a slight reduction in thickness, the method being applied to plates several millimetres thick and to aluminium sheets having a thickness of less than 0.3 mm, supplied, in either case, as independent plates or in a continuous roll.
Claims6
A method for engraving aluminium surfaces through a laminating process, comprising the following steps:
- a) Selecting a laminating cylinder;
- b) Adjusting the laminating cylinder to a Ra roughness between 0.02 and 0.25 microns;
- c) Incorporating an engraving to be transferred during the laminating process onto the surface of the laminating cylinder:
- d) Adjusting the laminating process with the desired speed, pressure and lubrication properties to obtain a reduction in the thickness of the material between 5 and 15%;
- e) Positioning the material to be laminated at the infeed of the laminating machine;
- and
- f) Conducting the laminating process to obtain the laminated and engraved material with the transferred design.
