How to Choose High-Performance Laser Heads
When selecting components for a laser marking machine, it is important to focus on the core parameters of the laser head, such as wavelength, power, and beam quality.When selecting a material, one must consider both whether it is suitable for the application and the long-term maintenance costs. I suggest that one should verify the stability of a product by means of field tests and user feedback.It is only by rationally matching performance and budget that one can find laser heads with a truly high price-to-performance ratio, and avoid problems that can result from low prices or exaggerated specifications.
It's important to understand what you need before you start.
Before you buy a laser head, don't rush to order.You have to be clear about what you want to do with the laser.For example, are you using it to cut metal or plastic? Do you need to work continuously for long periods or just occasionally? The requirements for laser wavelength and power vary a great deal according to the material.If you normally process highly reflective materials such as stainless steel, then a fiber laser head might be more suitable. If you mainly mark wood or leather, however, then a CO2 laser head will probably be more cost-effective.
The important thing is not the price, but the performance specifications.
Many people are easily attracted by low prices, but they can end up losing out if they neglect to consider the specifications.
The important factors are wavelength and power.
The wavelength directly determines what materials can be cut. For example, 1064nm is suitable for metals, while 10.6μm is suitable for non-metals.Power affects the speed and depth of marking, but it's not the case that the more power the better. Too much power can burn the material, while too little is inefficient.
Don't forget about beam quality.
The beam quality (M2 value) affects the marking precision, with values closer to 1 meaning a more focused beam.For those who want to engrave fine designs, it is suggested to select a laser head with an M2 ≤ 1.3.
Maintenance costs also have to be figured in.
Buying a laser head is not a one-time purchase. Maintenance is the hidden cost.
Ask about the lifespan of consumables.
The manufacturer will say how many hours the pump or the optics are good for.Some low-priced laser heads are cheap to buy, but if you have to replace the lens every three months, you end up spending more money.
The cooling system is very important.
The laser head is easily overheated, especially in the hot summer months in the southern part of Taiwan.Models with intelligent temperature control or dual cooling fans require less maintenance.
Try these little techniques to avoid falling into the trap.
When visiting a factory, don't just look at the samples.He would bring his own materials to test on the machine, and observe how well it cooled and how stable it was after half an hour or more of continuous operation.Then they ask for feedback from existing clients, especially from those in the same industry.Finally, be sure to check the warranty coverage. Is it just for the laser, or does it include the optical system?
