Differences and characteristics between CO2 glass laser tubes and CO2 RF tubes

Co2 glass laser tube

Mainly used to cut non-metallic materials, such as paper, bamboo products, acrylic, rubber and so on. How thick material can be cut is up to the cutting speed and cutting quality requested. Generally, the slower the cutting speed is, the thicker material it can cut, but the cutting edge is a little melt. Theoretically, the 25W laser tube has a low power and a small spot size, which is suitable for engraving, not good for cutting. For cutting materials, higher power CO2 glass laser tubes, like 80W, 100W, 130W, 150W are required.

The laser is the core of the laser equipment, and its quality directly determines the quality of laser machines, especially for small and medium power laser equipment. CO2 gas laser is the most widely used laser, and the most popular ones are glass CO2 laser tube and CO2 RF metal laser.

The disadvantages of Co2 glass laser tube

Although the price of traditional glass CO2 laser tube is relatively cheap, but its use failure rate is high, the life is short, the volume is large, and the beam mode is poor (the cutting line is thick). Its response speed is slow, and the low power output is not possible (the power adjustability is poor, and the same power laser has different effects on different materials.) These shortcomings are not only difficult to meet the needs of production and processing, but also restrict its long-term development.

In terms of service life, the glass CO2 laser tube generally can last 6000 hours, and the production capability can affected if there is failure in tube. Regarding operation cost, the glass CO2 laser tube costs about 1 yuan/ hour. In addition, it is also a consumable item. The longer the use time is, the higher the relative cost. With increasing requirements in production, CO2 glass laser tube is hard to meet the demands of industrial production. 

CO2 RF Metal Laser Advantage

CO2 RF metal lasers are one of the fastest growing technologies in the industrial laser market in recent years and are considered to be the best alternative to glass tube sealed CO2 lasers.

It adopts fully metallized structure, small size, fully sealed off, compact design, maintenance-free, low cost, and excellent modulation. It has high quality laser beam (more than 3 times finer than glass tube), high injection power density, low operating voltage, convenient output power adjustment, excellent power stability, and high operational reliability. More importantly, CO2 RF metal lasers also have a long service life (generally over 20,000 hours), low maintenance costs, and it can also be reused after refilling.

In addition, among all kinds of industrial lasers, CO2 lasers have the lowest output cost per watt and high plug efficiency, between 10% and 12%. Applications include processing on flexible materials, non-metallic solid materials and high-speed cutting, carving, and welding of metal materials, etc. These advantages make CO2 RF metal lasers be the optimal choice for industrial continuous production.

Advantages of SPT CO2 laser

As a leader in the field of CO2 laser, SPT laser has a leading position in the manufacture, maintenance and after-sale service of CO2 glass lasers and RF metal lasers.

At present, on products and solutions, SPT has CO2 glass laser tubes, high-quality CO2 RF metal laser with different power for users to choose, this advantage ensures that users can get the optimal product at the lowest cost. In addition, SPT also provides after-sales service such as maintenance, refilling at low cost with short leadtime. This is what other companies don’t have.

Prospects for CO2 RF Lasers

With the increasing demand and diversification of market demand, the traditional glass CO2 laser tubes is losing its advantages in the increasingly fierce market competition. However, CO2 RF lasers, with its superior technical performance, it benefits consumers with efficiency improvement, production transformation to have better profit, and plays a positive role to the improvement of corporate competitiveness.

In general, CO2 RF laser equals to advanced production.
