The use of our patented machine, programmable thanks to a PLC command, allows us to perform a wide range of designs in the engraving phase, such as: Shelled engravings to give it a reptile effect reproduced in various shapes and sizes, normal engravings, as well as askew engraving to give it a stretched, scratched look. They can be made in parallel lines or crossed, to form diamonds, square and other shapes.
