1 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

3 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

4 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 ~ W Higher power = higher speed. Higher Power = working less hard to achieve result = longer lifetime of the laser tube

5 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

6 9.35 µ m Wavelength – PET 9.35 µ m will mark glass / label but less power = less speed = less quality 10.6 µ m Wavelength – Glass 10.6 µ m will not mark PET

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

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

14 120 Watt specified but measured output 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

15 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

16 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) Benefits

17 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 Glass

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

20 The 10.6 µm wavelength laser can c ode 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 Glass

21 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

22 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

23 C ode 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 PET
