In virtually all the above operations some form of fume is given off as the laser thermally decomposes the substrate to a greater or lesser degree. Malgré tous les avantages de l'usinage au laser, les processus thermiques de ce dernier génèrent des émissions qui doivent être aspirées, et filtrées le cas échéant de manière fiable. Risque d'incendie. Acrylic placed outside is highly resistant to the elements. There is a company that makes an exhaust system that use carbon filters but the smallest unit sells for $2000. We are not aware of any trials. The short-wavelength fiber laser light goes right through the plastic without cutting it. Les films de polycarbonate, tels que le Lexan ou le Makrolon, peuvent être découpés très précisément avec un laser CO2. Grease-like processing fume condensates on ventilation ductwork, molds and other surfaces can cause irritation and injury to the skin. Ce n'est qu'en combinant correctement des lentilles optiques de qualité, du gaz de rinçage sûr, des buses de découpe en cuivre, de l'air comprimé propre et un système de table et d'aspiration adéquat que l'utilisateur laser critique obtiendra une valeur ajoutée.

Compare. laser cutting rule out the method. Impact on the environment and the surroundings from laser cutting acrylic at the Induflex facility. Explore outstretching collections of over-the-top polycarbonate laser cutting … In laser cutting, the laser beam depolymerizes the acrylic in its path - converting it back into its chemical constituents. As with all laser applications if the fume is not removed at source using LEV (Local Exhaust Ventilation), the fume can blur the laser beam, affecting its efficiency. Cleaning using water. Li> If the chimney is high enough, the natural degradation and the spreading means that nobody will notice the emission. Vente en ligne 24/7 d'accessoires, de matières à graver et autres consommables. A variety of toxic fumes and particulates are generated when different substrates are being lasered. Both as liquid and vapor. You can see the fiber marking came out fantastic but the cutting of polycarb looks very rough, this is why polycarb is a tough material to cut or engrave using a CNC laser. Estimated reduction of MMA concentration at the neighbors by a factor of 15. Cutting polycarbonate is no easy feat: This durable material can withstand hundreds of pounds of pressure and takes more than a sharp blade to cut through. (most noticeable on thick materials and more combustible materials.) MMA is NOT on the Danish Health Authorities list of unwanted substances and allows emissions of MMA of 2000 grams/h before a facility has to start cleaning. This is rare in saw cutting since, if done correctly, melting should be minimal. In Denmark, the largest manufacturer of acrylic is Altuglas in Brønderslev (formerly Repsol). As with laser cutting of fabric the edge will not unravel. So it’s quite obvious that the heat will undoubtedly cause the material to produce a lot of fumes. There are no known hazards associated with the fumes generated from saw cutting ACRYLITE® sheet. Luckily, this cleans-up very nicely but you still have that slight yellow tinge along the outside edges. Therefore, it should be quickly using ozone. If you do not mind the discoloration and fumes, you can laser cut very thin sheets of less than 1mm using a 10.6-micron CO2 laser.

The fumes from the laser cutting of acrylic consists mainly of MMA. Applying this knowledge we developed the ADVANTAGE range of fume elimination systems designed specifically for such a broad base of lasered substrate materials. US $2000-$3590 / Unit. Laser cutting is a poor choice for a thick polycarbonate panel of more than 1mm thick. Burning. Cutting. These contaminates are known within the industry as LGACs (Laser Generated Air Contaminates). It should therefore be possible to “wash out” the MMA from the air. Health concerns when laser cutting acrylic at Induflex. The above solutions, 1-3 are purification methods that mimic how MMA is broken down in the atmosphere. Metals are commonly worked substrate but organic materials (plastics, paper, wood) are also widely used. Papier et assimilés Papier / Cartons: oui! Laser cutting does however produce an enormous amount of hazardous contaminants that need to be removed to protect the operator and ensure the quality of cut. However, Class 3B or 4 lasers are the opposite, as these machines are more powerful and therefore more harmful. These fumes are extracted from the rear or base of the machines. These contaminates are known within the industry as LGACs (Laser Generated Air Contaminates). A variety of toxic fumes and particulates are generated when different substrates are being lasered. Up to 5 years warranty. Acrylic consisting of methyl methacrylate (MMA), which is a colorless liquid having the chemical formula: The composition of smoke from acrylic laser cutting. “It doesn’t even heat it,” says Vicent. Polypropylene, polyethylene and polycarbonate all generate benzene, a carcinogen, during laser cutting. Fume extraction systems are available in different configurations including exhaust port connection, multiple exhaust port connection, and standalone source capture. Li>. It will only slowly degrade and can remain outside for decades. A devise was test by Induflex, unfortunately without any recorded effect. For example, fume from Nylon when lasered is roughly 80% particulate to 20% gas, where as fume from Acrylic is 90% gas to 10% particulate. LGACs of different makeup can react in the extreme within the filter separation process. Ol>. Polycarbonate is a poor choice for laser cutting.
