Amsterdam, Holland – Selling Lasers > 25 YearsAmsterdam, 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 etcComponents 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 – PET9.35µm will mark glass / label but less power = less speed = less quality

10.6µm Wavelength – Glass10.6µm will not mark PET

Laser is designed to be placed above labellers or production lines.

Technical

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 densityOn 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 airNot 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)

Benefits

Many glass coding applications actually code onto the Label

High speed coding up to 73,000 bph for a 2 line code with laser integrationon label station.

Metalized labels are no problem.

On the label station the position of the label is very accurately controlled

Glass

The flexiblity and high speed of the MundiScan laser and galvo's allow multiple coding windows on the same label. Text orientation can vary.

The 10.6µm wavelength laser can code directly onto glassVery clear code on glass using 250 Watt peak power.Peak power is achieved by reducing the pulse frequencyIE. creating and releasing mini power surges Using this peak power the glass is fusedBold characters possible for better visibility No micro cracks in the glass

Glass

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 MundiScanon 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
