Amsterdam, Holland – Selling Lasers > 25 Years
Mundi Technology found a laser manufacturer who had a 120 Watt
scribing laser used for cutting and welding
This laser was very fast because of its high power, but was not suitable
for the beverage industry.
Mundi Technology developed the MundiScan based upon this laser
and the Heineken specification ( 2008 )
After a test period of 6 months on a production line in Heineken
Zoeterwoude, the MundiScan became the new standard for laser
coder within Heineken.
Heineken now have 25 MundiScan laser coders
2013 Available In The UK Via Mapex Inspection
History of the two companies working together for more than 16 years
Mapex Inspection having sold lasers in the past
MundiScan lasers are physically identical in a 316 grade
stainless steel case, however there are six principal variants
60W (9.35µm)
80W (10.6µm) (180 Watt Peak Power)
100W (9.35µm)
120W PP (10.6µm) (250 Watt Peak Power)
A 10.2µm laser is also possible to code laminates etc
Components are well proven in heavy engineering and are over specified
so 120W rated laser has typical measured output ~130-150 W
Higher power = higher speed.
Higher Power = working less hard to achieve result = longer lifetime of the laser tube
The choice of laser is derived from
– Substrate
– Quality Requirement
– Speed
– Coding Area Size
We offer a free of charge application evaluation service/sample marking
9.35µm Wavelength – PET
9.35µm will mark glass / label but less power = less speed = less quality
10.6µm Wavelength – Glass
10.6µm will not mark PET
Laser is designed to be placed above labellers or production lines.

Benefits
120 Watt specified but measured output 130-150 Watt.
Peak power approx double ( 250 Watt ).
By reducing pulse frequency it is possible to increase pulse power
More power means higher speed.
More power means longer lifetime of the laser tube
Small spot size ( larger galvo + smaller lens ) means high energy density
On glass this creates a very high temperature, fusing the glass giving a smooth
code which is immediately visible
Keyswitch protected Gravity & Spring Laser Shutter for improved safety
Components are ‘over specified’ and therefore almost never fail
MundiTechnology refer to it as “Install and forget !”
Benefits
Air cooled
Conforms with Green Brewery Regulations !
Air cooled by means of heat exchanger air to water.
No compressed air required
Compressed air not green and very expensive to run.
Can be £ 2,000 cost / year)
No blower units required
No water spillage
No chiller (not green, expensive , frequent maintenance/repair)
Benefits
Easy to integrate in small places. MundiScan has a very small print head.
Laser tube is in the machine. Tube life = 20K Hours laser on time
( microseconds on time per dot ).
The oldest tubes in the field are 6 years old; we have yet to see a failure.
50mm Ø articulated arm delivers laser beam to the print head.
Laser coder can be mounted up in the air
Not in the way for operators.
Clear and strong laser codes very readable. Code creation by row rather than by
column; creating a more consistent character set. Characters do not stagger.
Optimised for OCV
Can clearly mark difficult materials ( metalized labels / glass)
Glass
Many glass coding applications actually code onto the Label
High speed coding up to 73,000 bph
for a 2 line code with laser integration
on label station.
Metalized labels are no problem.
On the label station the position of
the label is very accurately controlled
The flexiblity and high speed of the MundiScan laser and galvo's allow
multiple coding windows on the same label. Text orientation can vary.
Glass
The 10.6µm wavelength laser can code directly onto glass
Very clear code on glass using 250 Watt peak power.
Peak power is achieved by reducing the pulse frequency
IE. creating and releasing mini power surges
Using this peak power the glass is fused
Bold characters possible for better visibility
No micro cracks in the glass
PET
MundiScan produces a very clear code on PET by 9.35µm laser
Bold characters possible for better visibility. Code is “foamed” not engraved.
Code does not impinge upon integrity of lightweight bottles
Large focal length (200mm) provides a big depth of field.
This means control of lens to product distance is less critical
PET
Mostly coding on conveyor post filler.
Condensation on bottles, has detrimental effect on the laser code.
A drying device is needed before the laser coder.
Laser head can be angled to match bottle contour ( neck )
High speed laser required where bottles are very close together
MundiScan produces a very clear code on PET by 9.35µm laser
PET
Code quality of MundiScan
on PET is very clear and visible.
Foaming
The high speed of the MundiScan laser
allows a longer path length. The “Wobble”
function is used to make the characters bold
Additionally, the laser power stresses the
stretched PET creating a “whitening” effect similar to that seen when too much
heat is used when bottle blowing
