DLM-BC Pro-D – Beverage closures additive-free laser marking

 
 

Closures laser marking system

DLM-BC and DLM-CR (Dynamic Laser Marker) series of laser equipment is designed for precise laser marking on the inside or outside surface of the beverage closures of all kinds, including plastic caps, metal closures, synthetic wine corks and crowns. DLM-BC Pro-D is designed for the laser marking of plastic beverage closures with the help of two laser sources with different wavelength (UV and Fiber lasers). The laser marking could be done with the both laser sources simultaneously or with any of the laser sources separately. Another advantage of the two-laser modification is that it allows mark the closures of any color disregarding the pigment or additive that is used in the closure material.

Plastic caps are transported on the conveyor belt to the marking area where marking process occurs ‘on-the-fly’. Software allows to mark logos, text, QR codes and numbers with randomizing option or numbers increment(decrement) as vector or rasterized graphics. The system can also work with codes database.

Laser marking is a flexible technology that allows you quickly change the job properties and mark unique image or text on every product.

Application fit

  •   Plastic beverage closures of all kinds.
  •   This technology proved a great success in promotional activities, counterfeit protection, and decoration technique for beverage products amongst others.

Benefits

  •   Dark on light material or light on dark material.
  •   Use of UV laser allows achieving of high contrast and perfectly readable white-color marking on red, green, dark-blue closures as well as other colors.
  •   Combination of UV and Fiber laser enables additive-free laser marking on almost all closure colors.
  •   High-contrast marking.
  •   No consumables.
  •   Maintenance-free technology.
