TRUMPF MAKES ITS MARK ON PLASTICS |
|
 |
|
TRUMPF’s new VectorMark compact 6 is a new precision laser marking system that achieves high-quality, high-contrast marks on most plastics and synthetic materials without the need for substrate additives. The marker’s 355nm UV wavelength is ideal for applications such as marking electronics where photo-sensitive pigments are generally added to change the materials’ dielectric properties. |

The frequency-tripled, diode-pumped, solid-state VMc6 laser system marks plastics at higher quality and at faster speed than traditional marking methods. Also, on most plastics the VMc6 achieves a much darker contrast than infrared lasers and without damaging the material or altering the part’s surface finish.
The system’s UV wavelength offers several advantages in the material processing of plastics. For example, the high photon energy of the new laser results in high-contrast marking through a photo-chemical process, rather than a thermal process. This ‘cold marking’ ensures minimal heat is introduced to the part and creates crisp high contrast marks without engraving or burning. This is particularly important in the manufacture of synthetic electrical and electronic components such as connectors, PLCs, relays and switches.

The UV wavelength also greatly increases the range of synthetic materials that can be marked with high quality and contrast. Excellent results have been confirmed on a very wide range of materials that previously could only have been marked clearly with the addition of photo-sensitive pigments.
The VMc6 is designed for highly efficient and low cost operation. Its vanadate crystal is mounted to a frame that is automatically moved at regular intervals. As a result, wear is spread out over the entire crystal and its life is prolonged dramatically.
In common with other models in the VectorMark compact laser range, the VMc6 is available as an OEM system for integration into automated production lines and as a stand-alone workstation with Class 1 safety enclosures and integrated fume extractors. As part of TRUMPF’s VectorMark family, the new addition offers high productivity and rugged durability, especially in multi-shift industrial operations.
