Videojet Technologies Inc. has introduced the 7810 Ultraviolet (UV) 2-Watt laser in addition to its existing CO2and fiber laser offerings.Laser technologyprovides permanent, high-resolution marking on HDPE, LDPE, and synthetic fiber materials. This system is suitable for pharmaceutical, medical, and cosmetic manufacturers as the surface of the product remains undamaged.
The code is resistant to abrasives, chemicals, and sterilization processes. Specifically engineered to allow high-speed, on-the-fly marking at speeds up to 250 ppm, the 7810 UV laser’s proprietary 360° Arc Software compensates for products on curved lines of movement to help ensure consistent, high-quality coding, irrespective of product orientation.
The 7810 UV is suitable for marking medical device products using synthetic fiber materials, such as DuPontTMTyvek® for sealing blister packs. UV laser properties ensure that the light amplification does not burn the fabric, therefore ensuring that there is little risk of code deterioration during the sterilization process.
The 7810 UV laser features product movement compensation software, known as 360° Arc. The software acts to counterbalance the orientation of products on curved lines of movement, common with rotary systems, helping to ensure consistent, high-quality coding. As the packaging moves down the production line, multiple concave mirrors deviate the UV beam to ensure that every part of the package can be clearly coded as needed.
The 360° Arc Compensation Software ensures that 2D and alphanumeric codes are consistently crisp, high resolution, and undistorted by natural movement during the production process. There is no need for additives to be included in the original plastic material for the laser to react accordingly and create the appropriate contrast mark. This allows customers to integrate the UV laser into production without the need to change existing processes or undertake revalidation processes.
