First of all, let’s talk about the concept of laser engraving. What is laser engraving anyway? Well, most of us would think that engraving is that some elder artist uses knives or electric tools to carve beautiful patterns out of wood, glass or other materials. But for laser engraving, the knives or electric tools are replaced by laser light. Laser engraving uses the high heat from the laser light to “burn” the surface of the item so that marking or engraving can be realized. 

Comparing with manual engraving tools, laser engraving machine allows controllable size and types for the characters and patterns. Plus, the engraving performance is more delicate. However, the laser engraved items are not as vivid as manual engraving ones, so laser engraving machine is mainly used for shallow engraving/marking. 

There are several kinds of laser engraving machines in the market and they can be categorized by different laser sources. Below we will discuss the pros and cons for these laser engraving machines. 

CO2 laser engraving machine - ideal for non-metal materials like wood, leather, plastic, etc. It is the most popular type of laser engraving machine in the market. Advantage: high power, fast engraving speed and high precision with wide applications. Disadvantages: the machine is kind of heavy and not easy to move. So it is more suitable for factories.

Fiber laser engraving machine - ideal for metal or materials with coating and high density. Advantages: fast engraving speed, high precision and ideal for batch production of factory and multitasking. Disadvantages: the machine is kind of expensive, generally more than 15000RMB. 

UV laser engraving machine - it is a relatively high end laser engraving machine with very delicate engraving performance . Advantages: wide applications for both metal and non-metal materials and multitasking. Disadvantages: the machine is 1.5 or2 times more expensive than fiber laser engraving machine. Therefore, it is more suitable for high-end manufacturing business.

Green laser engraving machine - most of the 3D image inside the acrylic is engraved by green laser. It is ideal for inner engraving transparent glass and so on. Advantages: as its description. Disadvantages: the machine is expensive.

Among all the above mentioned laser engraving machines, CO2 laser engraving machine and UV laser marking machine often need water cooling to take away the heat from the laser source. And if you go to the sign and label exposition, you can often see S&A low power industrial laser chiller standing next to these machines. Take S&A Teyu air cooled laser chiller unit CW-5000 as an example. This chiller is often installed to cool the CO2 laser engraving machine, for it is easy to use, easy to maintain and features a compact design. Small as it is, this low power industrial laser chiller can deliver 800W cooling capacity and ±0.3℃ temperature stability. Such a small but powerful chiller, no wonder so many CO2 laser engraving machine users have become its fan! Find out the detailed information of CW-5000 water chiller at
