Laser Cutting/Marking and Engraving
Laser Fume Extraction for Laser Cuttering, Marking, Coding and Engraving.
Cutting of materials such as metals, plastics and textiles is now commonly achieved using lasers. This has great benifits such as fast clean accurate cuts that often don't require any additional finishing. Laser cutting does, however, produce enormous amounts of hazardous contaminates, which need to be removed to protect the operator and ensure the qulaity of cut. As with all laser applications, if the fumes are not removed at source using Local Exhaust Ventilation (LEV), they can blur the bean, affect its efficiency and harm the operator,
A variety of toxic fumes and particulates are generated when different substrates are being lasered. These contaminates are known with in the Industy as Laser-Generated Air Contaminates (LGACs). LGACs of differen make-up can react in the extreme within the filter seperation process, in some instances have a high ratio of gases to particulates and vice versa. For example, Fume from Nylon when lasered is roughly 80% solid particulate to 20% gas, whereas fume from acrylic is 90% gas to 10& solid particulate.
