Industrial Galvo Laser Systems with a CO2 Laser Source

Marking and labelling metal and plastic parts with a galvo laser has become a standard operation in industrial production today. The applications and laser types (normally YAG and Fiber) are very well known, but the use of a galvo system with a CO2 laser source is much less conventional. CO2 lasers are usually perceived as flatbed laser machines, but CO2 galvo systems are being seen more and more in today's industrial landscape.

CO2 Laser Sources & Organic Materials

CO2 lasers are usually suitable for processing organic materials. This includes wood, paper, cardboard, textiles, foams and plastics - like acrylic and films. However, inorganic materials like aluminium can be processed wonderfully or ablated in a nice, defined manner with a CO2 laser machine. Usually, flatbed lasers would be used to process these kinds of materials. But, the disadvantage of flatbed systems is the slower processing speed.  This can be quite noticeable and problematic when mass producing fine details. Additionally, galvo lasers offer significantly better focus-tolerance. This means that minor irregularities in the material should not affect your result.

If the laser processing fields are small, and the numbers higher, galvo lasers give clear advantages on organic materials too. The application fields are diverse, including serial marking on wood as well as deeply engraving plastics and even cutting films and injection-moulded parts.

Lasers - A Replacement for Conventional Production Methods

or as a perspective for new production processes

Laser processing can introduce you to new production ideas that wouldn't have been possible before. One application that cannot be done without laser technology is PMMA cutting. The laser creates a clean, polished edge that doesn’t require any kind of post-processing. This can shorten your production time and raise your profits. However, to produce silicone seals and even some kinds of paper, galvo lasers are being used more and more - offering maximum flexibility and high throughput.

Flexible & Subtle Film Processing as a Typical Application

Lasers can cut and engrave extremely delicate geometries, which are impossible with mechanical cutting plotters and cutting dies. So, all the annoyances that come with these outdated methods - like high costs, delivery times, adaptation and storage - can easily be eliminated! Lasers are flexible, even when prototyping individual parts as well as during serial production. Electrical insulation foils, used in electronic components and electrical drives, are a typical example of where laser technology outshines conventional cutting styles. Even for kiss-cut applications where adhesive films need to be cut carefully to avoid damaging the carrier material, lasers are sufficiently suited.

The Right Laser System for the Respective Application

Today's laser possibilities are extremely diverse. So, it is important to select and design the right system with appropriate diligence for its chosen purpose. Trotec's galvo systems consist of these available variants, so your machine can be turned into a stand-alone workstation or even an automated version with input and output – the right system can be selected for virtually any application!

For example, Trotec offers the tried and tested SpeedMarker series with an attached 2-axle galvo as well as a 3-axle GS galvo laser system. This is advantageous in some applications due to its large working area and concomitantly small spot size.
