Neural networks combined with genetic algorithms and finite elements have been developed for fault detection and/or classification and sensor location optimization.
The objective of this project is to develop a reliable and flexible production line system for laser induced colouring, based on the use of suitable additives (pigments, dyes, and photochromic compounds and prechromic compounds) in polymer matrices. For this purpose insight has to be gained into the phenomena occurring during the laser irradiation of synthetic materials and the right combinations of materials have to be developed. Laser parameters have also to be evaluated thoroughly.
The project proposed here deals with the following 3 main objectives:
innovations in laser beam technology with surface treatment as the application;
the development of polymeric materials with optimised packages of functional properties (ie they become laser markable in a reproducible way);
the development of polymeric materials suitable for automated processing by means of selecting additives for improved processability.
In order to achieve the project aim, the following objectives are defined:
multicolour laser induced decoration on a dark background of a synthetic material, demonstrated on a laboratory scale;
multicolour laser induced decoration on a light background of a synthetic material, demonstrated on a laboratory scale;
demonstration of the possibilities of multicolour laser induced decoration in a pilot production multicolour laser system.
This project aims to develop a reliable and flexible system for laser induced colouring of plastics and lacquers for the decoration and labelling of industrial products, based on using certain additives (pigments, dyes, prechromic and photochromic compounds) in polymer matrices and applying laser irradiation of various wavelengths.
A study of the chemical, photochemical and physical phenomena, occurring upon laser excitation of pure polymer matrices, bare pigments and pigmented matrices, will provide the necessary background knowledge. A thorough evaluation of laser parameters and their influence on various effects in the material will lead to the right choice of laser technology.
The correct combination of pigments plus prechromic and photochromic compounds in adequate matrices must lead, under correctly chosen laser excitation, to coloured decoration or labelling of reproducible quality, having a clear contrast, high durability and a good wear resistance.
The aims are:
to write, in white and more than 2 additional colours, on a dark background of a synthetic material;
in black and at least 2 additional colours, on a light background of a synthetic material.
Laser induced multicoloured decoration will be demonstrated at the end of the project in a pilot production multicolour laser system.
