Some of our CO2 laser marking machine products Online CO2 Laser Marking Machine Integrated Laser Marking Machine Application Beverage packaging, wine packaging, food packaging, pharmaceutical packaging, cosmetic packaging, leather, electronics, IC, garments, textiles, cables, wooden crafts, building materials, tubing, communications, clocks and watches, glasses, printing plate making, plastic, rubber products, craft gifts, electronic components, advertising signs, model making, such as glass stone processing field. Applicable Materials Suitable for marking non-metal materials: leather, acrylic, epoxy resin, unsaturated resin, textile, plexiglass, ceramics, plastics, synthetic materials, wood, paper, PET, glass, cloth, rubber, etc. How much does a CO2 laser marking machine cost? There are many brands, and different brand has different price, with prices ranging from 3000 to 11,000 USD. Why is there such a large price span? We list for you several factors: (1) Which kind laser machine is suitable for me? a) Fiber laser marking machine is suitable for (but not limited to) metal laser marking, such as cans bottle body , metal wine bottle cap, etc. b) UV laser marking machine is suitable for (but not limited to) PE food packaging bags, etc., mineral water bottles, etc. c) CO2 laser marking is suitable for (but not limited to) plastics, such as plastic buckets, paint buckets, etc. d) Green laser marking machine is suitable for (but not limited to) glass ceramics, such as wine jars, glass wine bottles, etc. (2) How to choose CO2 Laser Marking Machine power? CO2 Laser Marking Machine power ranges from 3W to 60W. Some powers are adjustable and some are fixed. Different powers correspond to different marking speeds. Accessories quality determines production line stability, so power also determines the machine price. (3) What accessories brand to choose? CO2 Laser printers are mainly composed of lasers, field mirrors, galvanometers, industrial computers, cabinets, boards and other components. These accessories quality determines the laser machine performance and lifetime. Different brand accessories has different price. (4) Service quality CO2 Laser machine supplier services will influence price directly. The services provided by different CO2 laser marking machine brand merchants also directly affect the final price. After all, the cost of professional communication, the quality of service provided, the speed of response, and the attitude and commitment of after-sales maintenance are different. How do you use a CO2 laser marking machine? The machine is mainly controlled by software. It's very easy, not complicated. Before shipment, we will make a simple operation manual with pictures and provide user manual of software. Generally speaking, an operator, who is not familiar with CO2 laser marking machine before can still operate it very well. According to customers' requests, we can send our technician to customer' plant for machine training or customers can come to our plant for machine training if needed. How to delivery a CO2 laser marking machine? We mostly make delivery by sea for formal order. Of course, we can delivery goods according to customers' requirements. What's the co2 laser marking machine package? We have 3 layers package. For the outside, we adopt Wooden case. In the middle, the machine is covered by foam, to protect the machine from shaking.

First, the difference between CO2 laser marking machine and fiber laser marking machine are: two lasers are different, the beam emitted is different, and the processing range is also different. Fiber laser refers to a laser that uses rare earth element-doped glass fiber as gain medium. It鈥檚 wavelength is 1064nm. The advantages of fiber lasers are: glass fiber manufacturing costs are low, the technology is mature. Fiber laser machine is more compact, intensive, and has the advantages of no maintenance, and high stability, which is unmatched by traditional lasers. Fiber lasers marking machine are qualified for harsh working environments and have a high tolerance for dust, shock, humidity, and temperature. There is no need for thermoelectric cooling and water cooling, and only need simple air cooling, can greatly reduce costs. High electro-optical efficiency: The comprehensive electro-optical efficiency is as high as 20% or more, which greatly saves power consumption during operation and saves operating costs. It can process metal and some non-metallic materials. CO2 laser marking machine uses CO2 gas as the laser medium to emit laser light. Its wavelength isi 10.64um. It is mainly used for non-metallic materials, such as plastic and glass. But after a period of use, it need to be inflated (CO2 gas). The lifetime is about 30,000 hours, it can work for a long time, and it is the first choice for non-metallic materials marking. From the processing application, the wavelength density and the length of the optical fiber laser marking machine and CO2 laser marking machine are different. CO2 laser marking machine is 10.64渭m, it鈥檚 application: polyvinyl chloride (PVC), ABS, acrylic (PMMA), bulletproof glue (PC), unsaturated polyester (AK), polyurethane (EP), glass, wood , Paper, etc. The fiber laser wavelength is 1064nm, which is much shorter than CO2 laser machine, and metal absorption is good. It鈥檚 applicable industry: various metals and some non-metals, electronic separation components, integrated circuits (ICs), electrical circuits, mobile phone communications, hardware products, knives and kitchen utensils, tool accessories, precision instruments, glasses and watches, computer keyboards, jewelry accessories, Auto parts, plastic buttons, plumbing fittings, sanitary ware, PVC pipes, medical equipment, packaging bottles and so on. The application scope of fiber laser marking machine is different from that of co2 laser marking machine. Both have irreplaceable places, but fiber machine is relatively more widely used than CO2.Co2 Laser Marking Machine factory website:http://www.dopschtech.com/laser-marking-machine/co2-laser-marking-machine/
