Laser Marking For Product Traceability

WHAT IS LASER MARKING?

Laser marking is the use of a laser to make an identification mark on the surface of a material. Common types of laser marks for identification include part origin and date of manufacture, serial numbers, stock, lot, and batch numbers, inspection markings, logos, marks for assembly, positioning, and maintenance, as well as 1d and 2d barcodes. 

These permanent marks are used for part identification, authenticity, and product traceability throughout the manufacturing process and life of a part. Most manufacturers must follow strict guidelines as their products are heavily regulated.  Part identification and product traceability is essential for manufacturers to maintain compliance. 

There are several ways a laser can be used to make identification marks on parts.  The most common laser marking application processes are heat marks, etching, engraving, and carbonization. The best type of laser marking process used depends on several factors including the part's material, if the part will be used in harsh conditions, if it is a life-sustaining medical device, and how deep you want the laser to go within the material, and does it require corrosion-resistant marks. 

Each laser marking machine GT SCHMIDT manufactures helps our customers achieve the exact laser marking product traceability solution for their industry and exact part requirements. We offer both class 1 certified enclosure systems as well as open-source laser components.  We have a variety of laser sources including fiber, diode, YVO4, UV, green and CO2 lasers.  Our machines can be equipped with standard accessories and custom options to help support the marking process. Depending on the laser source we have two laser software options both with an intuitive interface and a graphic editor that will help get you up and marking in no time.

WHAT ARE THE BENEFITS OF LASER MARKING?

Lasers can quickly produce marks that are less than 0.005 inches deep (deeper marks are possible though those take more time). They are capable of producing a wide range of different kinds of marks, some of which can be made without weakening or damaging the material being marked. This can be especially important when you need to mark parts and surfaces that are thin or sensitive.

Additionally, lasers can produce high resolution, detailed marks of different colors, making this marking technology the most aethetically dynamic and pleasing marking technology available. 

WHAT KIND OF PARTS AND MATERIAL ARE BEST FOR LASER MARKING?

Lasers are capable of marking a wide variety of different materials, including:

  • metal
  • plastic
  • glass
  • ceramics
  • wood
  • leather

CAN I MARK ON ROUND AND FLAT PARTS WITH A LASER MARKER?

Lasers are able to mark both flat and round parts.

To mark flat parts, the laser lens simply needs to be set a certain distance away from the surface of the part being marked (that distance is determined by the laser and lens being used). The flat sides of a round part are marked the same way.

To mark around the diameter of a round part, we offer rotary chucks that can hold and turn the part during the marking process to get the best mark.
