Blaufaktor: Laser marking drinking water filters sustainably.
Sustainability and resource protection from the region.
In times of climate change and population growth, clean drinking water is an increasingly critical issue. Pharmaceutical residues, hormones, pesticide and antibiotic residues as well as toxins are often not even detected or filtered out by wastewater treatment plants and public drinking water treatment systems.
The drinking water filter supplier Blaufaktor GmbH & Co. KG has developed a solution to this problem with its Alb Filter brand. Since the development of the first Alb Filter in 2013, the concept has been continually improved and the application possibilities of the filters constantly expanded. Thus, the modular design of the various cartridges of the supplier can be addressed to the most diverse needs and application purposes of customers - whether for personal hygiene or drinking water, at home or on the road.
Mandatory traceability.
The aluminium water filters and accessory modules must be permanently and individually labelled due to mandatory traceability.
Previously, the basic housings produced in a lathe shop were taken to an external service provider for labelling and transported back from there to the actual filter production facility. The accessory modules were also marked externally. The compilation of the marked supplier parts caused considerable effort. So the search was on for a more logistically and cost-efficient solution.
In-house laser marking.
Blaufaktor opted for the SpeedMarker 700 laser marker, deciding to set it up directly in the turning shop, significantly simplifying logistics.
The stand-alone device with a processing area of 580 x 495 mm marks the manufactured parts directly on site, saving both delivery costs and times.
The self-explanatory menu of the SpeedMark laser software for template creation allows complex markings to be implemented quickly via a drag-and-drop function. The data is quickly imported via USB stick and the housing holders are assembled from simple plastic components.
In around 2 hours very good results can be achieved.
Since the laser system can mark a wide range of alloys, the technology will now gradually be adopted for other metal alloys to optimise the workflow.
Now that we are no longer dependent on a service provider, we can respond even faster to individual customer requests for marking with serial numbers, product designations or logos at lower cost.
