Suitable types of metal for laser marking

When marking and engraving on metal laser technology has been used to achieve great results for many years. Not only soft metals, such as aluminium but steel or very hard alloys can be marked accurately and quickly using a laser engraving machine to produce highly legible markings. Consistently high quality is guaranteed by the definition of parameters. The ability to achieve corrosion resistant markings on certain metals by annealing, for example on steel alloys, which do not damage the surface structure of the metal offers many advantages, particularly in business sectors, such as medical technology or the automobile industry.

Suitable types of metal for laser marking

  • Stainless steel
  • hardened metals
  • alloy steels
  • high-speed steels
  • aluminium
  • anodised aluminium
  • titanium, titanium alloys
  • hard metals
  • brass
  • copper
  • precious metals
  • coated metals

Depending on your requirements metals can be engraved or marked.


Examples



Application examples made of metal

Typical application areas for laser marking metals include product markings for traceability and codes. These can be found in the electronics and electrical industry, mechanical engineering and tool manufacturing, in sheet metal processing, medical technology, promotional materials and jewellery as well as in the automotive industry.

  • Product labelling as an anti-counterfeiting measure,
  • Functional labels such as size, diameter, etc.
  • Production information, such as date of manufacture, batch number, serial number, etc.
  • Traceability codes
  • Data Matrix codes for quality assurance
  • Customisation of promotional and gift items made of metals
  • Dataplates

Why should I buy a laser for laser marking metal?

Non-contact, permanent metal marking: Laser marking metal is an extremely precise and clean way to process metals. Labels, such as serial numbers, Data Matrix codes and logos can be applied to products and components with a high-resolution finish. Metal marking or engraving is created by the laser using a non-contact process that requires no pre or post processing. Markings produced by annealing serve as durable, acid, chemical and corrosion resistant labels that do not damage the metal surface.

Function and advantages of laser technology

Cost-efficient production

[]

  • Direct marking does not engender costs for consumables, such as inks, chemicals, pastes or sprays.
  • Likewise the need for handling and often pricey disposal of these materials is eliminated.
  • No pre or post treatments are required
  • Tool wear is eliminated

Advantages of a Trotec laser

  • The SpeedMarker with a maintenance-free fiber laser can be integrated as a laser workstation or into a production line
  • The robust mechanics of Trotec laser systems have been designed for many years of intensive use with minimal servicing.

Marking takes seconds and consequently allow for greater throughput

[]

  • Very fast marking is possible including marking of variable contents, e.g. serial numbers, codes
  • A wide range of different markings are possible without retooling or tool changes

Advantages of a Trotec laser

  • Intelligent and intuitive marking software for ease of use
  • Fast and highly accurate positioning of components by means of a camera system: SpeedMark Vision Smart Adjust
  • Integration of contents from ERP files is also possible

Permanent engravings

[]

  • Unlike other technologies, laser marking is permanent and abrasion as well as heat and acid resistant
  • Especially important for traceability and quality assurance

Advantages of a Trotec laser

  • Product portfolio with matching fiber laser systems for all requirements
  • Flatbed systems with processing areas of up to 726 x 432 mm
  • Galvo workstations with processing areas of up to 620 x 315 mm
  • OEM galvo fiber lasers for integration into production lines
  • Custom-built systems according to customer requirements

Perfect marking results - fine tools

[]

  • Precise and even the smallest geometries can be marked with extremely high accuracy
  • Marking processes can be combined to clean the material after processing or to provide a higher contrast (e.g. Data Matrix codes)

Advantages of a Trotec laser

  • High-quality optics and optimal beam quality thanks to high-quality components
  • Camera-based component positioning for high precision and ease of use

Incredible design opportunities

[]

  • Virtually any design can be realised with the laser.
  • It is even possible to create 1-point fonts and the smallest geometries that are still clearly legible.
  • Complete freedom in the design of markings, logos, designs, bar codes or serial numbers
  • Even photos can be implemented in the shortest possible time.

Advantages of a Trotec laser

  • DirectMark or JobControl software for laser marking or engraving directly from the graphics program makes everything as easy as printing

Non-contact and reliable material processing capabilities

[]

  • There is no need to firmly clamp down or fixate materials
  • Save time and achieve consistently good results

Advantages of a Trotec laser

  • Broad product portfolio with the right laser system for every requirement
  • Highly accurate laser marking even on your ""first attempt"" thanks to camera-assisted positioning.

"The huge bed size of the Speedy 400 we have has allowed us to mark up to 90 components at a time, which has greatly reduced our overheads but also increased the quality of the finished product. We’ve also been able to expand the business, because now we can engrave a company’s logo on their new equipment, which we’ve been able to capitalise on"
- Stuart Rogers, - General Manager of Doughty Engineering Ltd -
"We decided to go with Trotec because the offered the most reasonable solution at the most affordable price. In fact, the machine has been more than reasonable, it has been fantastic! Our laser has allowed us to expand because our production runs are now much faster. On top of this it’s also made things a lot easier because pretty much anyone on staff can be taught how to use the machine."
