50-Watt Fiber Laser

In response to manufacturers’ requirements to laser mark on plastic packaging, metal containers and other industrial products faster with more code content, Videojet Technologies has introduced a 50-Watt fiber laser marking system – the Videojet 7510 – to complement its existing 10-Watt and 20-Watt fiber laser offering.  The new 7510 marking laser is specifically engineered for high speed beverage, pharmaceutical and extrusion manufacturers that need to code data such as expiry information, lot numbers, batch numbers and other critical production information onto robust materials including plastics such as High-density Polyethylene (HDP), Polyvinyl Chloride (PVC), Polypropylene (PP) and Nylon, as well as metals such as aluminum and stainless steel.  The new 50-Watt fiber laser marking system extends the capabilities of the Videojet fiber laser offering.  For substrates like aluminum and extruded plastics, the new 50-Watt fiber is 65-95 percent faster than the 20-Watt offering in short product pitch applications, bringing all the advantages of fiber laser marking to an entirely new set of higher speed, and higher content marking applications.  Pharmaceutical companies can achieve up to 50 percent faster coding on blister packs and over double the speed on vials when compared to using the 20-Watt fiber.The 50-Watt fiber laser marking system directly addresses the growing need for manufacturers to increase lines speeds and maximize throughput.  Certain metal and plastic applications, typically found in beverage, canning and extrusion operate at very fast production speeds. 

The 7510’s high speed capability is complemented by an exceptionally large marking window – up to 498 millimeters in length – which provides more time to engage a moving product to achieve the desired mark.  “Our new 7510 brings an optimal combination of power, spot size and choice of marking fields to deliver a significant increase in marking speed and throughput,” said Markus Vetter, Laser Business Manager, Videojet.In addition to faster line speeds, the 50-Watt fiber laser provides a higher quality beam compared to Nd:YAG lasers, which allows it to run faster than traditional solid state lasers of higher power. Added Vetter:  “As an example, the 7510 is up to 63% faster than our legacy 100 Watt Nd:YAG laser for printing on plastic and metal packaging.  An added benefit of the higher quality beam is that it produces better looking marks on certain materials.  Effectively, this means packaging professionals can now select the Videojet 7510, our fastest laser to date, to put more content on their packaging, and optimize the aesthetics of the mark.” The 7510 marking unit is dramatically smaller than the predecessor solution.  At 74 percent smaller than the 100W Nd:YAG marking unit, the 7510 enables a far easier integration into packaging lines and equipment. A choice of working distances, varying from 122mm to 543mm, allows users to work within the physical constraints of the packaging line.  This, along with the choice of a straight or 90 degree marking head orientation, provides flexibility on production lines with space limitations. The new 7510 fiber laser has been designed to minimize downtime, increase reliability and run more efficiently.  The absence of lamps and diode pumps eliminates the pump chamber maintenance found in most conventional high-powered laser systems such as Nd:YAG solid state lasers.  In addition,  the air-cooled laser source reduces the complexity and maintenance frequency associated with external water-cooled systems.
