How to choose the right power?

As you know, 20W, 30W, and 50W are the most commonly used power for fiber laser marking machines. the laser source brand such as raycus,ipg,jpt etc..

But how to choose different laser power? 

Is there a big difference between these watts? 

We’d like to share some details with you.

20w fiber laser marking machine

The most hot-selling system by lowest price advantage. Especially on plastic and hard metals, it occurs perfect results. automotive, packing, kitchenware equipment, hand tools sectors are the main ways preferred on 20w. The 20W machine is mainly used for surface marking of plastic, stainless steel, aluminum, and so on.

30w fiber laser marking machine

Suitable for job shops and people who need more power. If you want to engrave deeply, then a 30W machine will be a better choice. For all materials, aluminum is the easiest to achieve deep engraving. There are many gun manufacturers and metal suppliers in the USA, so for this customer, a 30w machine will be a better choice.

50w fiber laser marking machine

Does deep engraving, micro-cutting, marking, and 3D engraving perfectly. Mostly preferred by the jewelry sector, One of the fastest models in the market.

CO2 marking machine VS Fiber marking machine

CO2 laser marking machines and fiber laser marking machines are two kinds of marking machines commonly used in the market. 

This article will mainly introduce the differences in processing methods, machine characteristics, and application fields between co2 laser marking machines and fiber laser marking machines. 

I. Processing method. 

The CO2 laser marking machine uses the medium infrared band 9.3 ~ 10.6 μ m for marking. 

By filling co2  gas into the high-voltage discharge tube to produce glow discharge, the gas molecules release laser, and the laser energy is amplified to form a laser beam for material processing. The laser beam gasifies the surface of the machined body to achieve the purpose of engraving.

The fiber laser marking machine refers to the laser marking machine which uses the rare earth element doped glass fiber as the gain medium. Under the action of pump light and positive feedback loop, the laser is directly output by the fiber laser. 

Fiber laser marking machine has the advantages of good beam quality, long life, and fast marking speed, and is widely used in automotive machinery, electronic communications, hardware equipment, buckle signs, instrument glasses, and other industries.

2. Features

Co2  laser marking machine

The marking accuracy is high, the speed is fast, and the carving depth is controlled at will. 

CO2 laser marking machine has high laser power and can be used for carving and cutting a variety of non-metallic products. 

Laser marking is clear, not easy to wear, fast carving and cutting efficiency, environmental protection, energy saving. 

The whole processing process of laser marking will not cause other damage to the outer packaging of goods, no waste of ink consumables, and no environmental pollution caused by exhaust gas and other problems. 

Good beam mode, stable system performance, and less maintenance, so it is suitable for industrial processing field with large batch, multi-variety, high speed, and high precision continuous production.

Fiber laser marking machine

Fiber laser marking machine has extremely high pump efficiency, with a pump conversion efficiency of 70% to 75%, which is much higher than that of industrial diode-pumped solid-state lasers (DPSSL). Such a high conversion efficiency reduces the need for cooling and power. 

Fiber laser marking machines can process a variety of non-metals, especially high hardness, high brittleness, and high melting point materials, high production efficiency, stable and reliable processing quality, good economic and social benefits. 

Compared with the traditional solid-state laser marking machine, the fiber laser marking machine has a more compact structure, high energy density, high speed, small heat-affected zone, and small workpiece deformation. It’s Widely used in automotive machinery, electronic communications, hardware equipment, buckle signs, instrument glasses, and other industries.

What is MOPA Marking Machine?

MOPA laser marking machine (aluminum blacked laser marking machine, color laser marking machine) belongs to the category of laser marking machine. MOPA laser marking machine uses direct electrically modulated semiconductor laser as seed source (MOPA) fiber laser. Compared with a Q-switched fiber laser, the pulse frequency and pulse width of the MOPA fiber laser are independently controllable and can be adjusted by two laser parameters.

The high-speed scanning galvanometer system can achieve constant high peak power output and can be applied to a wider range of marking substrates. 

With high-quality laser beam, low cost, maintenance-free, suitable for aluminum oxide blacked, 304stainless steel color, anode stripping, coating, semiconductor and electronics industry, plastic and other sensitive materials marking and PVC plastic pipe industry, marking out the pattern font environmental standards in line with ROHS standards.

The pulse width of MOPA laser marking machine M6 pulse width is 2-200ns. 

The pulse width of the ordinary laser marking machine is 118-126ns, so we can see that the pulse width of the MOPA laser marking machine can be adjusted more widely, so we can understand why some products can not achieve the effect of the ordinary fiber laser marking machine, but the MOPA laser marking machine can do it. 

However, when purchasing MOPA laser marking machines, many customers expect it to process at the same speed as ordinary fiber laser marking machines, but this is obviously counterproductive. 

When carving a color effect, the machine needs to mark it with a minimum shadow effect at high frequency, which makes the resolution of the sculpture high, but at the same time, the engraving speed is much slower. 

In addition, in metal deep engraving, MOPA laser marking machines may not have an advantage, but the effect is much better than ordinary laser marking machines. 

Therefore, before customers choose to buy MOPA laser marking machine, they need to understand the advantages and disadvantages of this kind of laser marking machine.
