Some heat-based processes, notably laser cutting, are generally considered impossible, owing to the equipment risk. [8] Where PVC materials are cut by laser, this is a highly specialized process requiring adapted machines and acid-specific fume extraction and filtering. [9]
In 1994 it acquired Directed Energy, a small laser marking business based in California, United States. [4] In 2004 it acquired Wiedenbach, a supplier of ink jet printers, and Purex, a supplier of fume extractors for laser printers. [5] In 2005, it acquired Sator, a supplier of laser printers.
The goal of a fume extractor is to move these environmental pollutants away from the user and other occupants of the room as quickly and efficaciously as possible so as to stay within the safe exposure limits of the various substances present, and reduce the risk of adverse health outcomes like metal fume fever, polymer fume fever, occupational ...
Animated sequence of how a bore evacuator works. A bore evacuator. A bore evacuator or fume extractor is a device which removes lingering gases and airborne residues from the barrel of an armored fighting vehicle's gun after firing, particularly in tanks and self-propelled guns.
Laser engraving metal plates are manufactured with a finely polished metal, coated with an enamel paint made to be "burned off". At levels of 10 to 30 watts, excellent engravings are made as the enamel is removed quite cleanly. Much laser engraving is sold as exposed brass or silver-coated steel lettering on a black or dark-enamelled background.
Laser cutting works by directing the output of a high-power laser most commonly through optics. The laser optics and CNC (computer numerical control) are used to direct the laser beam to the material. A commercial laser for cutting materials uses a motion control system to follow a CNC or G-code of the pattern to be cut onto the material.
