How to Select a Laser Engraving Machine

When ceramic manufacturers are selecting laser marking equipment, they often fall into traps because of the complexity of the specifications and the large number of suppliers.We will help you avoid common pitfalls and grasp the essential points of choosing an industrial marking device.

Why do ceramic factories need laser marking equipment?

The markings on ceramic products have to be both clear and attractive, but they cannot damage the product itself.Traditional ink printing is easily rubbed off, and machine engraving is easily chipped.Laser marking technology is a non-contact technique that can leave a lasting mark on plates, tiles, and even art ceramics. It produces a detailed pattern without damaging the glaze.In the last few years, after many ceramics factories have upgraded their equipment, the rate of good products has risen by more than 20 %.

These are three of the most common mistakes people make when choosing equipment.

They just look at the price, not the specifications.

Some low-priced equipment on the market boasts "high performance to price ratio," but in reality either the power of the equipment is exaggerated, or the speed of the laser is slow.Ceramic materials are very dense, so I recommend using a fiber laser of 30 watts or more. Only then will it have enough power to penetrate the surface of darker glazes.

Ignoring material compatibility.

The lasers needed for blue-and-white porcelain and polished tiles are different, so don't be taken in by the "universal" laser.The most reliable method is to bring a sample and test it on the spot. The most important thing to look at is whether the finished product has any cracks or turns yellow.

After-sales service is a big problem.

Last year, one factory bought second-hand equipment because it was cheap.When signing a contract, be sure to confirm the warranty period and the speed of spare parts supply. If possible, choose a brand with a service center in Taiwan.

Only then can you choose with a clear conscience.

First, clearly define the production needs.

For large-scale production, automatic machines with automatic loading and unloading are selected.If you are going to mark more than 5,000 items a day, remember to use a dual work station to alternate tasks.

The key is to focus on core parameters.

The marking accuracy is at least 0.01 millimeter, and the repeatability accuracy is no more than ± 0.02 millimeters.Don't forget to check out the heat dissipation system--only a machine that can work eight hours without slowing down is a good one.

Don't be lazy about field trips.

He would take a few pieces of different thicknesses of scrap ceramic to the factory to test the machine, paying particular attention to whether the edges were even and whether the glaze was scorched.Experienced salesmen would adjust the parameters on the spot to suit the customer, and these service providers are worth working with.

Tips on maintenance.

The optical lenses are wiped clean every week, and the laser cooling fans are checked every month.If the color of the laser marking fades, there is an 80 % chance that the lens is dirty or the laser tube is worn out.In southern areas which are humid, it is important to pay special attention to preventing dampness. Putting a few packets of desiccant in the equipment room can save a lot of repair costs.

Finally, don't let yourself get taken in by the "imported parts" hype.Nowadays, domestically produced lasers can last for 30,000 hours, so the key is selecting a mature model that has been tested by the market.
