Zintec (which is simply zinc coated mild steel sheet) can easily be laser cut using nitrogen or compressed air as the cutting assist gases. We can use either gas for cutting sheet metal with our Trumpf 3030 3KW fibre laser. When nitrogen is used as a cutting assist gas it will give the best possible clean cut finish with no signs of oxidization around the outer profile or inner holes and cut-outs within the component.
Compressed air is an interesting alternative to nitrogen, it’s a much cheaper cutting gas and often gives as good a finish on thinner gauges and can cut internal parts perfectly well even without any post laser cutting de-burring.
Oxygen when used as a cutting gas is normally employed on thicker gauges of material or mild steel when it’s going to be zinc plated. We don’t use oxygen to cut Zintec sheet metal components so you are ensured the best possible quality of sheet metal work from V and F Sheet Metal.
All our laser cutting work is programmed using Radan sheet metal software. Parts are modelled in 3D and unfolded to ensure the correct flat pattern sizes are calculated. The parts are tooled, tagged where necessary and nested for the most efficient use of material and machine time. This helps us to offer you the best possible prices we can but with a level of quality that you would expect from the latest fibre laser cutting technology.
The examples of laser cut zintec shown here in our gallery are typical of the sheet metal work we are laser cutting every day at V and F Sheet Metal. For more examples search our blog posts or call us on 01486 577786 and our engineering team will be happy to help you with your sheet metal project.
