Laser coding systems

Domino has pioneered the use of sealed CO₂ laser systems and today is one of the largest international producers of this technology. Through research and product innovation Domino has created laser coding systems that continually set the industry standard.

Marking is achieved by using a laser system to etch or vaporise the surface layer of the material leaving an indelible permanent mark. Domino has developed Scribing and Dot Matrix laser coders that can print text, graphics and variable data onto a variety of substrates including plastic, glass, paper and cartons. As there are no inks or fluids used, laser systems are environmentally friendly and very cost-efficient.

Scribing Laser systems

Domino's scribing lasers, such as the S-Series plus and D-Series plus use a continuous laser beam guided by mirrors that are controlled by galvanometer assemblies. The galvanometer technology enables laser coding and marking onto moving or static products at high speeds.

Key Benefits

• Superior letter-quality print
• High reliability due to few moving parts and proven CO₂ laser system technology
• Consistent quality on stationary and high-speed lines
• Print in any orientation
• Unlimited graphical capabilities
• Minimal maintenance, making laser coding environmentally friendly

Dot Matrix laser coding

Domino's dot matrix laser coding system uses a proprietary seven laser-tube technology.

RF energy is used to stimulate the lasers inside the print head of the DDC3. This in turn fires the lasers to produce a vertical column of seven separate dots that converge onto the product.

This laser system relies on the movement of the product to build these lines into dot matrix characters.

Key Benefits

A dot matrix laser coder may be appropriate for your business if you are looking for a system that offers:

• Very high speed printing of near-letter quality text
• High reliability due to no moving parts
• Range of laser-tube wavelengths, which ensures package integrity while coding onto a variety of materials from labels to PET
• Minimal maintenance and environmentally friendly printing

Domino's dot matrix laser system offers reliable, high speed printing that should meet all your requirements.

Fume Extraction

Laser coding and marking produces fumes and particulates as the surface material is burned. Fume extraction is essential to remove these potentially harmful by-products from the atmosphere.

How it works

The DPX range uses a two stage filtration process for maximum and cost-effective fume extraction. The extracted air is first passed through the pre-filter process which removes the majority of particulates.

The air is then passed up to the main filter which removes the remaining extremely fine particles, and is then filtered through a carbon-layer to remove any harmful gases. The clean air is finally returned to the atmosphere.

Sensors in the extraction unit check the purified air before it is returned to the atmosphere. If any particles or gas are detected, the DPX unit is automatically shut-down and an alarm is raised, ensuring that contaminated air is not released. 

Key Benefits

It is vital that effective fume extraction is in place when using laser coders to print. The reasons for this include:

• Compliance with health and safety regulations
• Ensures a clean and safe operating environment
• Improved production efficiency and reduced downtime costs
• Ensures consistent code quality
• Easy to use and maintain
