Timeless impressions - FOBA Laser Marking + Engraving | Alltec ...

6 7
Many requirements. One solution:
The process solution for laser engraving
in the mint industry
Digitizing, 3D or deep engraving, latent images, smoothing, frosting, surface texturing,
edge lettering, and direct marking of the finished product: Our laser-based process
solution encompasses all the steps involved in the tool and die production as well as
direct marking – all in one process chain. Minting dies and tools can now be completely
manufactured, and end products such as coins and medals refined by the laser.
An intelligent, integrated, coherent process solution that bears the name FOBA G-Series.
FOBA process chain
→ Laser deep engraving
of dies, tools, etc.
→ 1. Artwork
An artist’s model (plaster or wax) is created.
→ 2. Scanning/Digitizing
Digitizing of the artist’s model or, as the case may be,
the minting die template of the historical image of
the coin or medal to be reproduced via a 3D scanner.
→ Three-dimensional laser
engraving
of minting dies, tools,
punches, etc.
→ Laser latent images
for the protection
of valuable objects
→ Smoothing
of engraved areas
→ 3. Software
3a: Continued processing of the data scanned in step 2.
3b: Direct creation of a 3D model within the software
(eliminates steps 1 and 2).
Steps 3a and 3b are executed with 3D-enabled
CAD software (e.g. CopyCAD or PowerSHAPE by DELCAM)
or with the implementation of engraving and/or relief
processing software (e.g. ArtCAM).
→ 4. Importing data into laser engraving machine
– Importing of the 3D data (files) in FOBA EMC
– Process control (axes, parameters)
– IMP (Intelligent Marking Positioning via
camera system)
– Online depth control
– Beginning of processing
→ Micro engraving
to apply finest structures
to tools and stamps
→ Frosting (partial)
of minting tools or
finished products
→ Direct marking
of finished coins, medals,
objects of value, etc.
(special edition coins, direct
marking in edge areas)
