How Do I Choose A Laser Marking Machine?
Direct component marking with a laser marking system offers durable, high-quality, high-resolution, red dot laser markings.
The resulting bright red color of the dot-matrixed parts identifies the parts.
The advantages of this high-tech marking system are improved productivity and efficiency with little downtime and waste.
More visibility and increased accountability through the supply chain.
Laser Marking Machine
Choosing the right laser marking machine depends on your needs and budget. If you need to replace a number or even hundreds of parts, Meccano is an ideal choice for you.
The mecco machine consists of a series of metal slot machines with red dot laser markers in common. These machines are operated by a computer system and a control station.
You add parts to the slot machines and activate them according to preset procedures.
There are other types of marking systems and machines in the market today. For example, the fiber laser engraver machine is also available.
This machine can produce text-looking precision and high-resolution laser marks. However, the engraving process is more difficult than with the mecco style machine.
It also costs slightly more.
UV Laser Marking Machines
Another type of marking system is the UV laser marking machine. This machine produces light using ultraviolet (UV) radiation.
The machines that use this method work well with metals that have high resistance to UV rays. However, this type of machine may not be suitable for working with alloys or other metallic stains.
Since the UV lasers are very strong, the materials are usually required to undergo several treatments before the final color is achieved.
There are three types of UV laser marking machines – pulsed, continuous-wave, and directed-beam.
Pulsed beams are the most suitable if you want to produce highly detailed and fast permanent laser markings on thin or intermediate grades of metals.
Continuous-wave machines offer a higher level of accuracy, but they are more expensive. While directed beams can produce fine results on any surface, they are less effective for intricate designs.
- Meanwhile, etching systems allow the user to engrave shapes on the surface. Etching techniques include impulsive, laser, or gas etching. Many companies manufacture etching equipment to produce high-quality laser systems for this purpose. Etching machines work by passing electrical pulses through the metal that is to be engraved.
- High-quality laser marking machines should provide accurate control over the engraving depth. The most important parameters to check are the perforation depth (the distance between the holes) and the engraving speed. Another factor that should be taken into consideration is the machine feed rate. Feed rates should be variable to maintain the proper engraving speed.
- The final product should meet your requirements and expectations. Once you have decided upon the type of machine and acquired the appropriate supplies, you should test the system to ensure that it can produce the kind of results you want. A good laser engraver produces lines of perfect marks, and it takes only a few seconds to perform the task. With the latest technology, this can now be done with ease.
There are two basic types of laser markers available today. One type uses CO2 lasers, while another uses argon gas.
To determine which one to use for your purpose, you should note the following safety considerations.
Laser markings produce highly bright and highly visible images.
Therefore, you should take special care when using these machines and wear protective clothing such as safety glasses or goggles.
If your purpose is to mark the object’s surface, you can probably use the machine’s on-off switch to set the engraving feature.
However, if you need to create highly detailed, professional-looking lines, you should opt for a CO2 laser engraver.
These lasers are extremely accurate and produce little light. This means that you can easily mark thick and heavy materials.
However, CO2 lasers are quite expensive, so if you plan to mark a lot of material with them, you may need to buy several CO2 lasers instead of an air-powered one.
For heavier and thicker materials, you should use a diamond-tipped wheel for your CO2 laser etching equipment.
The diamond tips are effective at smoothing the surface of the material. However, they generate a lot of heat, so this technique might not suit certain applications.
A laser engraver with a rotating diamond wheel would be a better option, as this device produces less heat but is still effective enough to mark most surfaces.
Annealing is a technique that takes the annealed laser ink and applies it to a hard surface. Annealing helps in creating a flat, evenly-spaced coating on the surface.
Some people prefer to use the annealed laser etching process to produce a surface evenness without using a heat gun.
