Materials that cannot be cut by laser cutting machines and why

Although laser cutting machines can cut many refined things, there are also many materials that seem to be suitable for laser cutting machines, which cannot be cut with laser cutting machines (although they seem more suitable). Hebei Hongte equipment is You provide the materials that cannot be cut by the laser cutting machine and why.

Material Hazard Factors Causes and Results PVC (Polyvinyl Chloride)/Vinyl/Artificial Leather/ Artificial leather emits chlorine when it is cut! Do not cut this material, because it will damage the optics, cause metal machine corrosion, chlorine release, and damage the motion control system. Thick (>1mm) polycarbonate/Lexan cuts badly, fades, and fires Polycarbonate is usually a flat sheet material. The window of the laser cutting machine is made of polycarbonate, because polycarbonate strongly absorbs infrared radiation! This is the frequency of the light used by the laser cutting machine to cut materials, so it is very ineffective when cutting polycarbonate. Polycarbonate is a poor choice for laser cutting. It will produce long plumes of soot, floating in the air, destroying the optical system, and making the machine run chaotically. Acrylonitrile-butadiene-styrene melt/cyanide ABS does not cut well on laser cutting machine. It tends to melt rather than evaporate, and has a higher chance of catching fire and leaving melted sticky deposits on the vector cut grid. It also cannot be sculpted well (again, it melts easily). Cutting ABS plastic will release hydrogen cyanide, which is unsafe at any concentration. HDPE/plastic baby bottle melts on fire and it melts. It becomes sticky. It is on fire. Don't use it. Styrofoam catches fire. It catches fire quickly, burns quickly, and melts quickly, leaving only very thin fragments. This is the first material to cause a laser fire!! Polypropylene foam will catch fire just like polystyrene. After it melts, it will catch fire, and the melted water droplets will continue to burn, turning into water droplets and pebbles that are as hard as rocks. Epoxy Burning/Smoke Epoxy is an aliphatic resin with a strong cross-linked carbon chain. The carbon dioxide laser cannot cut it off, and the chaos generated by the combustion produces toxic gases (such as cyanide!). Epoxy resin or cast epoxy resin cannot be used for laser cutting machines. (See glass fiber) Glass fiber emits an odor. This is a mixture of two materials that cannot be sheared. Glass (etching, no cutting) and epoxy (smoke) coated carbon fiber are a mixture of two materials that emit toxic gases. The thin carbon fiber mat can be cut and has some wear-but not as a coating. Any food (such as meat, seaweed slices, cookie dough) laser is not used to cut food, the things people cut will produce toxic substances such as wood smoke and acrylic smoke. If you want to cut food, you can consider sponsoring a food-only laser cutting machine to keep the commercial kitchen clean. The material covers the lens with a viscose backing. Cracked lenses have many items that can be peeled off under normal conditions, such as veneer laminates you can buy. When the manufacturer applies a layer of peelable glue on the bottom, it cannot be cut. Such as cork tiles, veneer laminates, acrylic tiles and paper stickers. If these materials have this kind of backing, never use a laser cutting machine to cut them. The glue will evaporate and form a coating on the lens. The coating will cover the lens, turning it into a cloud, heating it, and then may crack the lens. The remaining glue is worse than resin. If it is not removed, it will cause damage to the lens... The lens needs to be replaced.
