Five Key Parameters for Selecting the Right Fiber Laser Marker
The article explains five key parameters for choosing a fiber laser marking machine, including power, wavelength, and marking speed, to help users select the right equipment based on their production needs.It is suitable for manufacturers, procurement managers, and production managers.
Why is it so important to choose the right parameters?
Many friends who have bought fiber laser marking machines have been attracted by the "high performance / price ratio" and "versatility" touted by the vendors, only to find that the machines can't keep up with production when they get to the factory, or that the materials aren't compatible.In fact, it's just like buying a car: you can't just look at the exterior, but you also have to pay attention to the core specifications.Now let's talk about how to make decisions based on real needs and key points.
Step 1: Clearly define your production needs.
Materials determine the basic configuration.
Don't rush to look at the specifications. First, take a piece of paper and write down what materials you want to cut.Metals, plastics, ceramics? Different materials vary greatly in their sensitivity to laser wavelengths.For example, a 1064nm fiber laser is most suitable for marking stainless steel; to mark plastic, you might need a green or ultraviolet laser.
The demand for production affects the choice of equipment.
Small-scale custom production and 24-hour assembly-line production are two completely different things.If you have to process thousands of parts a day, I suggest you consider a machine with automatic material handling and a high-speed galvanometer. Even though the initial cost may be higher, in the long term it will save you a lot of labor and time.
Step 2: Keep a close eye on these five key parameters.
More power is not necessarily better.
People often ask, "Which is better, 50 watts or 30 watts?" But it really depends on the application.For etching a logo onto a cell phone case, 20 watts is enough, but for deep etching into a metal mold, you might need more than 100 watts.Too much power is not a good thing, as it can burn the material. I suggest you choose the middle value that best suits your needs.
The speed of the labeling process hides a cost trap.
The maximum speed on the parameter chart is just for reference. The actual marking speed is greatly affected by the complexity of the pattern.Focus on the stability of speed under common patterns. If possible, take a sample to the site to test.Don't waste money on a top speed you'll never use.
The precision of the repetition determines the quality of the product.
This is a parameter that is of particular importance to those who do precision machining. If the repeatability of the equipment is less than ± 0.01 mm, then there is a tendency for the workpiece to be out of position during batch production.Here's a tip for you: If you print 20 identical QR codes in a row, you can easily see how accurate a scanner is.
The quality of the laser light affects the detail of the image.
If you want to engrave a 0.1-millimeter font, the closer the beam quality (M2 value) is to 1, the better.This parameter determines the size of the laser spot after it is focused. A larger number means that the laser spot is larger, and is like writing with a broad-tipped pen--you can't get any detail.
The cooling system is related to the life of the equipment.
I've seen too many factories where the laser dies early because of heat problems.Air-cooled equipment is cheaper, but not very tolerant of high temperatures. Water-cooled systems are more stable, but require more maintenance.Friends in the south should pay special attention to moisture control, and not allow the machinery to turn into a steam room.
Step 3: Hidden costs.
Ask about replacement parts.
The cost of replaceable items such as the galvanometer mirror and the laser protection mirror can differ by as much as three to five times depending on the brand.It is suggested that when signing a contract, the supplier be required to write down the prices of the most commonly used spare parts, to avoid being gouged by "spare parts assassins" in the future.
Software compatibility is very important.
Don't just look at the specs! When you're trying out the machine, be sure to put in some of the design documents you normally use (such as DXF or AI format). Some of the cheaper machines don't support complex vector graphics very well, and you can be worn out by the time you're finished revising the design.
The response time for after-sales service is crucial.
Find out whether your warranty includes a service call, and check whether there are service points in other provinces.Last year, one of our clients tried to save money by buying equipment from another area of the country. When the machine broke down, the engineers took three days to arrive, which meant that production was stopped for three days.
That's a fair exchange.
You might suggest that they draw up a comparative table, with columns for the five key parameters, component cost, and service terms.Don't be afraid to take a list with you and discuss it with the salespeople. This will not only increase efficiency, it will also help you avoid being taken for a ride.If you're not sure, it's best to bring samples of the material to the factory to see how it performs under actual conditions.
