Laser engraving

Permanent marking of plastics by laser engraving

Plastic promotional items, plastic signs or industrial parts can be engraved permanently, tamper-proof and in high quality with the laser beam. Due to the great flexibility and the short set-up times for laser engraving on plastic, we can also engrave small batch sizes for you at a reasonable price. Engraving on trophies made of acrylic glass also delivers impressive results thanks to the high-contrast, noble milky white appearance.

Practical examples for laser marking of plastics

Three advantages that are imprinted in plastic

1. precise

By engraving plastic, even the smallest details of motifs can be immortalized on your promotional item or cleanly sealed cut edges can be achieved during laser cutting .

2. resistant

Durable laser marking of a wide variety of plastics ensures that your logo, serial number or lettering remains permanent, because the laser marking is resistant to abrasion, sunlight and solvents.

3. exclusive

With laser engraved logos you enhance your advertising material with durability and exclusivity.

Versatile applications of plastic engraving

Technical info about plastic engraving

While the CO2 laser mostly produces a laser engraving without contrast on plastic, the YAG laser achieves contrasts by color change or foaming. Here, the associated material removal is minimal. This means that the mechanical properties – especially the strength of the material – are retained as far as possible.

What effects can be achieved on plastics using laser marking?

  • When engraving by a laser beam, the top layer of the plastic is removed, the laser vaporizes the material and the inscription becomes tangible.
  • In the thermal modification method, the laser beam melts the plastic, creating small gas bubbles that become trapped in the cooling material. This process is also called “foaming“. This allows bright laser markings to be produced on dark plastics.
  • If you want to achieve a dark laser marking on light plastics, the color change effect is chosen. In the process, the laser burns individual components of the plastic – this gives the motif the color of the core material. The color change depends on the pigment composition of the plastic and the color of the base material.

What does laser cutting mean?

We most often use this laser application when cutting acrylic sheets for special shapes of trophies or table displays or for cutting plastic signs. More complex shapes are also feasible up to a thickness of 6mm.

The following plastics can be cut by laser: Acrylic, polycarbonate, polypropylene and polyethylene.

What are the maximum dimensions possible?

  • For flat surfaces, we can produce laser engravings up to a size of approx. 40 cm x 60 cm on plastics.
  • The height of engraved letters on plastics should be at least 3 mm to maintain legibility of the writing.
  • For rounded surfaces, the size of the possible engraving is based on the thickness of the rounding. Hold a ruler to the curve – the maximum distance between the glass and the ruler must not exceed 2 mm, otherwise the laser engraving will be blurred.

Which materials are suitable for laser marking on plastics?

Plastics are more or less suitable for laser marking, depending in particular on the exact material composition.

The following plastic types were basically classified as machinable:

  • Polyamide (PA)
  • Polyoxymethylene (POM)
  • Polyester (PES
  • Polyethylene terephthalate (PET)
  • Polyimide (PI)
  • Polystyrene (PS)
  • Polymethylmetacrylate (PMMA)
  • Polycarbonate (PC)
  • Polypropylene (PP)
  • Acrylonitrile butadiene styrene copolymer (ABS)
What do I do if my product is not suitable for art engraving?

Some types of plastics cannot be engraved because the heating melts the material. In this case we recommend UV direct printing or our Visdome 3D stickers.

Laser engraving is also used on products made of:
