Laser Marking System for Cards EM-237
The EM-237 Laser Marking System is designed for marking or engraving of a broad range of products made of metal, ceramics, plastic and other materials through controlled material evaporation in the radiation impact zone.
The EM-237P Laser Marking System for electronic plastic cards (EPS) is intended for marking EPS through controlled material evaporation in the radiation impact zone.
The marking data are formed in the external computer (IBM PC) which carries out authentification of the EPC, creates the marking logo in AUTOCAD editor or CorelDraw, transmits the data to the system’s computer, corrects data base after marking a EPC batch.
The loading-unloading device allows automatically to feed in step a batch of EPS from the loading cassette to the probing and marking positions and into the receiving cassette. Combination of authentification and marking operations of the preceding EPC allows to shorten the batch marking time for EPC. The system is equipped with a Nd:YAG laser (TEM00 with λ=1064 nm ) having an acusto-optical Q-factor modulation . The system can make marking from an external control as well as in an automatic mode.
Optic mechanical device based on electromagnetic scanning deflectors, controls the laser beam motion according to preset algorithm and provides the next parameters:

Control and Software System Control system based on IBM PC and provides the following:
- control to all drives, loading-unloading assembly
in off-line mode and external control mode;
- storage and automatic selection of treatment
modes according to preset process parameters;
- editing of marking layout to be processed in own
editor and AUTOCAD 14 system as DXF file;
- inspectionl of average laser power with display
of pictogram on computer screen;
- control to R.F. driver;
- display on TV-screen of the on-line information
(process steps, prompting of operations sequence,
error warning, etc.);
- creation and storage of the library of programs
of operations including layout pattern and list of
process parameters;
- actuating mechanisms diagnostics.
