The diverse system sizes from eurolaser are suitable for both large-format textiles and foams and the exact cutting of foil sheets. Laser Cutting - nothing compares to the quality of a laser cut on many materials. Alibaba.com offers 305 polyurethane laser cutting products. That gives them a very small dot, which gives a sharper etched image, but it also means they can only cut very thin materials. Numerous types of gaskets and foam parts are easily laser cut with our lasers. A lot of lasers are sold primarily geared toward etching, so they have a very short focal length. The cutting of polyurethane with CO2 laser systems is characterized by a high level of precision and flexibility. Acrylate polymers, for example, react especially well to CO2 laser cutting. Laser Marking - how can you affordably mark metal parts with barcodes and logos? If there's enough oxygen in the air, inert gasses like neon or argon won't do anything whatsoever. MDF/Engineered woods 1/4" These are okay to use but may experience a higher amount of charring when cut. In the case of 3M Polyurethane Foam, virtually no HAZ is created because the low density foam structure … How to Cut Polyurethane Moulding. As you can see from the reverse picture, it has a pretty cool cut pattern. This area of thermal affect is often referred to as the heat affected zone or HAZ. Even for larger quantities laser cutting now constitutes a real alternative to conventional processing methods such as die and knife cutters (cutting plotters). Compared to the complex water jet cutting process, the laser is significantly faster, more flexible and more efficient. Tool configuration, geometry, and placement, as well as rpm are dependent on what hardness the urethane is and what the operation is. As for charring, it often depends very much on the particular material, including contaminants, e.g. Most elastomers vaporize quickly when cut with a laser, resulting in smooth and straight edges with minimal heat … Engraving and cutting these materials can cause irreversible damage to your machine, so determining the components of your cutting and engraving materials is extremely important. The main materials shops will process will include wood, cardboard, aluminum, stainless steel, plastic, tile, … By the 3rd try, the kerf is pretty tight. The parallel use of CO or please call for your individual consulting! They also say that ABS and PVC are fine. Etching can be done on almost anything, wood, cardboard, aluminum, stainless steel, plastic, marble, stone, tile, and glass. Foam cutting with a laser machine … The material just outside of the laser's spot or path will conduct some heat but not enough for complete and thorough ablation. Hydrogen cyanide (HCN) is bad news. About 8% of these are laser cutting machines, 1% are sheet metal fabrication. We would be glad to advise you on the topic of the laser cutting of polyurethane, on our laser systems and special options for the processing of plastic. This foam is ideal for laser cutting. What is confusing about this is that polyurethane is generally considered a very "laser friendly" material to cut (stated all over the place on laser hobbyist and professional websites under acceptable materials). … Its properties make polyurethane a versatile material that is very durable, mould and mildew resistant and, depending on manufacture, hard and brittle or soft and flexible. Eurolaser.com isn't a good source for this kind of thing. PUR, PU, Cellasto ®, Elastocoat ®, Elastoflex ®, Elastofoam ®, Elastolit ®, Elastopal ®, Elastopan ®, Elastopor ®, Lupranol ®, Baydur ®, Bayfill ®, Bayflex ®, Baylit ®, Baymer ®, Baytherm ®, Desmodur ®, You will find videos showing the laser cutting of polyurethane at eurolaser.tv. how charring leather is when laser-cut largely depends on how it's been treated. If the laser power is sufficiently high, the laser beam will cut completely through the material. But how do you determine what makes up the material you want to laser cut or engrave? I'm getting some conflicting information when searching for safety information on laser cutting TPU. For these reasons, CO 2 lasers are commonly employed for laser ablation of polyurethane foam. Too much oomph. © 2015 - 2019 eurolaser GmbH. #1 can be mitigated by a few "test fires" while holding a fire extinguisher at ready, but the worst case is messy, #2 I will always avoid because the machines are expensive and high-maintenance as they are. Laser cutting systems are generally superbly suited to the processing of various foams. Other CO2 laser cutters for cutting polyurethane (PUR). Even then I'll cringe pretty hard while doing it and I probably should not do it at all. Plywood/Composite woods 1/4" These contain glue, and may not laser cut as well as solid wood. Foams made of polyester (PES), polyethylene (PE), polyurethane (PUR) are well suited for laser cutting, laser engraving and laser marking. Particulate left behind in vent system and within the machine could be hazardous if ingested. Polyurethane (PUR) is a plastic or synthetic resin. Foam is used for many different applications including suitcase inserts or padding, seals and artistic applications like souvenirs or photo frames. Each and every XT Laser series is capable of marking on tungsten and carbide and the ideal system for your application depends on your marking requirements. We can laser cut open cell and close cell polyurethane foam up to 1″ thick. Laser etching can produce great results on almost any organic material. This particular laser cutting tool is a popular alternative to other manufacturing tools. You can work directly from the design program, which is very important especially in the area of rapid prototyping. A wide variety of polyurethane laser cutting options are available to you, such as ccc, iso. It's the same reason why you shouldn't cut/engrave ABS. The MSDS for Elastollan (BASF's trade name for TPU) states: Decomposition products: carbon monoxide, carbon dioxide, hydrogen cyanide. Expanded polyethylene (aka polyethylene foam) is one of the most popular foams used in the industrial sector, due to its lightness, insulating properties and resistance. The cutting of polyurethane with CO 2 laser systems is characterized by a high level of precision and flexibility. These resources caution against cutting polyurethane due to HCN gas: http://www.materialseducation.org/educators/matedu-modules/docs/Laser_Cutter_Materials.pdf https://www.synrad.com/sites/default/files/2018-07/Laser%20Processing%20Guide%20%28Plastics%29%201.04_0.pdf, While other sources call polyurethanes safe to cut or recommend it for laser cutting: https://www.lasercuttingshapes.com/materials/ https://www.eurolaser.com/materials/polyurethane-pur/.
