Laser Engraving Technology Advantages For Your Jewelry work

Over the past decade, laser engraving machines have revolutionized the jewelry work.

We see a constant increase in jewelry businesses that utilizing laser technology to offer bespoke and customized items for their customers.

This article explores the benefits of laser technology and shows you some of the main advantages comparing to traditional engraving methods.

Foremost, a single laser system can engrave multiple surfaces.

That means that you only need to buy one laser engraving machine to be able to engrave silver, gold, copper, titanium, brass and tons more applications.

In fact, a fiber laser machine can also engrave non-metal surfaces, such as acrylic, plastic and wood.

The other benefit for jewelers is that we can use a single machine to individualize and personalize different shaped items.

So, whether you’re looking to engrave rings, bracelets, necklaces or watches。

The only restriction is the size of your machine’s marking area.

Although that is typically not a concern, as jewelry items tend to be small in size.

1.Advantages of laser engraving

Versatile

You can create virtually any design, no matter how complex, and have it successfully engraved onto your jewelry item.

Even the smallest of designs remains legible when marking with a laser beam.

Thanks to its versatility, Jewelry designers use the laser machine for countless applications.

Non-contact

The fiber laser machine uses a non-contact marking method.

Essentially, a laser beam is directed onto the item’s surface and produces a mark by removing the material.

As a result, there is no contact between the laser equipment and the jewelry item.

Since there is no contact during the engraving process, the jewelry item being marked is never compromised.

Additionally, the machine doesn’t have moving parts, which can wear down over time and require replacement.

You also don’t need to trouble yourself with tightly clamping or fixing the jewelry item to an engraving bed.

You just place the item in the right position and press the start button to begin the engraving process.

Time-saving

There is no doubt that one of the most significant advantages of laser engraving is the time you save!

Of course, the engraving time per item varies depending on the complexity of your design and the depth of the engraving.

However, it’s safe to say that the average job takes anywhere from a few seconds to a few minutes at most!

How do I ensure high-quality effect with fiber laser marking machine-lisa

Jewelry laser cutting machine using tips

No matter what marking technology you use or what material you’re engraving, high-quality marks are key to improving traceability, minimizing counterfeiting, complying with industry regulations, and enhancing quality.

One Ask an Engineer question we often get is “How do I ensure high-quality marks?” To get consistently clear and readable marks, first of all, it’s important to make preventative maintenance programs part of your continuous improvement efforts to avoid costly waste and downtime in the future. But, if you’re noticing blurry, indecipherable or otherwise subpar marks, there are a few ways to troubleshoot:

MEASURE FOCAL DISTANCE OF LASER MARK MACHINE

If you’re seeing mark degradation, one of the first things you want to check is your focal distance. Focal distance is the measurement from the object you’re marking, or your marking plane, directly to the laser lens. If the offset between these points is the wrong distance, it can mean the difference between a sharp mark and a blurry mark.

Precision is key. There are several options when it comes to measuring this distance. One common tool is a focal stick. You can also use a laser displacement sensor or a laser pointer to automate this measurement. The bottom line: measure twice, mark once

MAINTAIN LENSES FOR FIBER LASER MARK MACHINE

This is an obvious yet overlooked issue affecting mark quality. Anyone wearing glasses out there knows that if you can’t see properly, try cleaning your lenses. The same rules apply to your laser marking machinery. Any type of residue buildup, such as oil or dust, in addition to scratches or cracks can disrupt the laser beam path and degrade your marks.

To clean lenses, we recommend using acetone or a low-water-content solution of isopropyl alcohol, 98% alcohol content or higher. To clean lenses, wear protective gloves and apply the solution to a cotton ball or microfiber cloth. Make sure the lens is free of any rough pieces of grit to avoid scratching the lens surface.

Avoid lens issues altogether by developing a regular preventative maintenance schedule to maintain your lenses.  Depending on your environment, this schedule could range anywhere from weekly to yearly. Taking the time to ensure your lenses are debris- and scratch-free will give you better marks in the long run.

EXTRACT FUMES

Lasers displace material as they mark a surface, which creates debris and fumes. Materials with a lower burn point such as plastic can generate a great deal of exhaust. If not properly directed, the plume created by the exhaust can travel back into the laser beam path, which can degrade the laser power, causing blurred marks.

Avoid exhaust-induced laser degradation by making sure you’re extracting the plume in the right direction and with the proper flow. The fume exhaust tubing should be close to the marking plane and drawing exhaust away and out of the laser beam path. Think of exhaust in the laser’s path like headlights on a foggy morning. For clearer, more precise marks, give your laser clearer visibility by properly extracting fumes.

Something about the lens introduction

Lens size

When customer purchase a laser marking machine, the one important question is the lens deciding. Why this is so important? It is because the machine will only with one lens.  So that means if you choose one which is  incorrect. Then your machine may not able to achieve what you want it to do. So in usual, there are these model below:

50 * 50mm, 110 * 110mm, 175 * 175mm, 200 * 200mm, 300 * 300mm.

The lens‘ price are same. So there are lots of customers are willing to choose bigger size. Because the model defined by working area. The customers who want the biggest one was thinking that might process bigger stuff. But is the idea correct?

Definitely no, I always say that there is not a machine could do anything for you.

How to choose lens?

First you need to know what is the maximum size you need to mark for your object. If the object is only 100*100mm, Then you choose 110*110mm. Do not choose bigger size. Because laser is a kind of light. If you do want to engraving, deep engraving, or even cutting. The lens you choose bigger, it means the laser from two sides are weaker.

When the scanning area reaches a certain level, the light spot diameter is very large, not sufficiently fine. Because the spot becomes large,the distortion increases,so the power density of laser decreases rapidly, and the working distance lengthens. This inevitably leads to the loss of laser energy. So it doesn’t conducive to precision machining.

By the way, when customers choosing it, the customers also need to consider the overall configuration. If you already decide to purchase a 20w machine. But you still want a 300*300mm lens. Then the power of laser is very weak.

So  in short, to choose best one for a machine, you need to consider it carefully.

How to adjust the marking depth of the laser marking machine

The laser marking machine uses laser beams to mark the surfaces of various substances permanently.

Comparing with inkjet marking, the advantages of laser marking are as follows.

a wide range of applications, a variety of materials (metal, glass, ceramics, plastics, leather, etc.) can  permanently mark with high quality.

No action on the surface of the workpiece, no mechanical deformation, no corrosion on the surface of the material.

Here is a brief introduction to the method of marking depth adjustment:

At first, the most direct adjustment method: increase the power of the laser marking machine.

Secondly,Modify the marking speed: other parameters remain unchanged, the marking speed is slow down, the marking depth will be deepened.

Thirdly, Transforming the field mirror: Turning the field mirror into a small range of field mirrors, after the transformation, the depth of the marking will also become deeper.

Fourthly,Field mirror replacement: the replacement of the field lens can also deepen the depth of laser lettering.

Fifthly, The laser mode is better, and we could improve the marking depth.

Sixthly,Replace the laser.

Replace the laser with a higher power, directly increase the depth of the laser code printer lettering.

In the end, Replace parts: replace better laser marking accessories, such as semiconductor laser marking machine, the use of imported Q switch, its marking depth will be better.

Why Mopa?What is Mopa’s work?

Compared to usual Q-switch laser,Mopa’s main work is below:

*Mark color on stainless steel
*Marking good black color on anodized aluminum
*Mark on plastic

Difference between mopa and Q-switch?

Mopa(JPT) and Q-Switch (Raycus,IPG)
Same:1064nm wavelength laser beam
Difference:
Mopa———Pulse width (2-200ns), Pulse frequency (1-1000HZ) , so MOPA laser is more flexible.
Q-Switch—- Pulse width and pulse frequency are fixed, can not be changed.
Pulse width (90-130ns),Pulse frequency(20-80 kHz)

Mopa can do all the Raycus‘ work.
Mopa  > Raycus

Mopa’s work introduction

Firstly,Mark color on stainless steel.

The best lens for color marking is 175*15mm or 200*200mm.

For 300*300mm lens,it can not mark color.

For 110*110mm lens,the parameter is not easy to adjust.

Secondly,Mark good black color on anodized aluminum.

Usual Q-switch Raycus laser can not mark black color on anodized aluminum.

If customers want to mark balck color on mobile casr,they have to choose the Mopa laser.

How to choose a fiber laser marking machine

If you are interested in buying a fiber laser marking machine, you most probably have the work you want to do with the machine figured out.

What you need now is a quick analysis of the equipment that best suits your purpose.

For example, how deep is the fiber laser marking machine you are looking to do?

Different models will give you different depths and marking speeds.

As much as it is important to understand the different machine designs, price ranges and features, you also want to look at other extra offerings whichever target company you have is giving you.

For example, if you land on XT, one of the leading Chinese suppliers of these machines, you will get five offerings;

1.Different models of fiber laser marking machine

Desktop Fiber Laser Marking Machine 

This is a low power consuming, high speed machine that supports 24-hour operation.

Fiber laser marking machine has a work life of 100,000 hours, and its price ranges from $3500 – $5500 depending on your customization needs.

It gives a 10-20W output laser power and achieves and engraving depth of up to 0.2mm.

Standalone Fiber Laser Etching Machine  

The two main differences between the FL20 and FL10 is the output laser power and design.

This machine is standalone as the name suggests and manages 20W-30W output.

It comes at a price of between $2600 – $6000 depending on the customization required.

It is an ideal laser etching machine for metal working in a small to medium enterprise.

It has a 50W laser output with speeds of up to 9000mm/s.

Setting marking parameters in fiber laser marking machine software-Angelina

Setting marking parameters in fiber laser marking machine software

In marking metal and plastic,There is a setting parameter range for reference to test in the fiber laser marking machine software .

Speed 100-2000 adjustable,Power 30-80 adjustable,Frequency 5-30.

Depends on different materials and the marking effects you want so for a new operator may need conduct dozens of trials to know the ideal marking parameters for each material and even some experienced engineers have to try several times.

Here have a brief introduction about laser marking frequency,power,speed and the hatch function .

1.two settings for fiber laser marking machine software

1.)  In laser marking machine,Marking frequency stands for the times of laser pulse per unit time.

It is easy to understand.

For example, When the value of marking frequency is high, the laser spot is dense.

On the contrary if the marking frequency value is low then the laser spot is parse.

Although we cannot see the laser spot by the naked eye,we can see it when we put the marking workpiece under the electron microscope.

The continuous line we see by eyes turns out that is composing by many laser spots.

The high value we set at marking frequency,the denser laser spot we get and more smoothness we will get on the marking workpiece.

2.)  Marking speed refers to the moving speed of the laser.

Here this speed is the speed that can be adjusted in the parameters for marking.

The overall marking time is not only affected by marking speed,but also by the marking depth, marking area and other factors.

The higher speed you set,The faster marking speed you get.

Fast marking speed means less laser hitting times in the same marking place.

Slow speed is more conducive to deep marking .

But it does not mean the slower speed you set, the better depth you will get.

It also depends on the different materials and other relative parameters you set at.

Creat jewelry with laser machine

laser marking machine    

The laser processing of materials for the production of jewelry is one of the fundamental prerogatives of the laser systems.
Laser welding, laser marking and cutting make it possible to reach high quality products but not only on today’s jewels. Even on vintage pieces and on costume jewelery. Where the material is of poor quality but where it is possible to make cheap repairs.

The new technologies in support of the goldsmith’s art are available from laser machine.

  • The YAG laser allows to repair, embed, polish and complete objects with precious stones without causing thermal shock and metal withdrawal;
  • With the YAG laser it is possible to weld objects without using soldering alloys which inevitably lead to color variations, with a consequent depreciation of the value;
  • Using our lasers, no finishing and cleaning operations are necessary when finishing the workpiece;
  • Finding a small hole in a final polishing ring can be a problem. But with the laser it can be managed in no time and an invisible repair is easily obtained;
  • Resizing a platinum ring with a junction that leaves no trace is only possible with laser, because it is stronger than any other solder.

 

What else is it possible to do with laser in jewelry?

  • Assemble pieces with very different thicknesses, for example;
  • It is also possible to assemble pieces made of different alloys such as gold and steel;
  • The YAG laser does not oxidize and makes it possible to recover pieces that have come out with defects from the casting process;
  • Filling an engraving on a piece of jewelry to make a new one is easy, using a wire of the same material by laser welding.

What about jewelry design, since laser has been created?
The way of thinking about jewels has definitely changed, because now they can be made using materials that until recently were not taken into consideration.
The laser is changing the jewelery industry, improving the working conditions of the operators and expanding the possibilities of movement.

In addition to the repair of jewelry with laser, another important part is their marking and cutting for jewelry materials

The fiber optic laser makes it possible to carry out very precise processes. Just think about marking of rings and how do procedure in an excellent way.
Whether it is internal or external laser marking on the rings, with XT Laser machines every operation is simpler.

Marking objects of any metal is no longer a problem, you can engrave photos, logos, brands.

In summy, Producing or repairing jewelry with laser is the future of jewelry!
