Laser marking machine frequently asked Questions?

1 What is a laser marking machine?

Ans: Laser marking machine - In common language laser machines are an unusual source of coherent, monochromatic light beams.

A laser is one of the biggest technical achievements of 20th century that produces a very narrow beam of light that is useful in many technologies and instruments. The letters in the word laser stand for Light Amplification by Stimulated Emission of Radiation.

The laser light waves travel together with their peaks all lined up, or in one phase which is why laser beams are very narrow, very bright, and can be focused into a very tiny spot. When pointed at something, the energy of the narrow beam of extremely directional light, having high intensity stays focussed at a tiny spot producing accurate, precise and sharp marks on the product of any shape, size and material.

The three basic components of a laser marker are:
  • Lasing material (crystal, gas, semiconductor, dye, etc...) or a laser medium
  • Energy or Pump source
  • Optical cavity consisting of optical resonators to act as the feedback
Types of laser markers:

Laser markers are often described by the kind of lasing medium they use

  • Solid state marking lasers have lasing material distributed in a solid matrix, e.g., the ruby or neodymium-YAG (yttrium aluminium garnet) lasers. The neodymium-YAG laser emits infra-red light at 1.064 micrometers.
  • Gas lasers -helium and helium-neon, HeNe, are the most common gas lasers and are used for cutting hard materials.
  • Excimer lasers.
  • Dye lasers use complex organic dyes like rhodamine 6G in liquid solution or suspension as lasing media. They are tunable over a broad range of wavelengths.
  • Semiconductor lasers, sometimes called diode lasers, are not solid-state lasers. These electronic devices are generally very small and use low power.
Time modes of operations of laser machines
  • Continuous Wave (CW)
  • Single Pulsed (normal mode)
  • Single Pulsed Q-Switched
  • Repetitively Pulsed or scanning lasers
  • Mode Locked lasers
2 How much is the minimum font size that our laser can mark?
3Is the laser marking permanent or gets erased after some days?
4What is the production per day - How many pieces per day?
5What is the maintenance of the machine?

Ans: Machine will require zero maintenance if operated within a standard clean environment. We recommend a gold suction system. Not only does it capture gold dust, but it also helps the conductive dust to stay away from the electronics.

6 What is the possibility of inner marking on curved bangles or ring?

Ans: Curved surface of diameter ranging from 0.8-1 mm can be easily marked. ( Kerf Width ). We have special tools like motorized rotary chuck to engrave inside the curve with ease.

7What happens to the gold loss while marking?

Ans: Our Goldwin - The Gold dust collector is very efficient. It can capture almost entire Gold as powder thus we can help you to recover the gold lost in the process.

8Life of our laser machine?

Ans: Life of a laser machine is solely dependent on the life of laser source – MTTF +100000 hrs. For 5-8 years the machine runs very efficiently though frequent checkups are required.

9 Can Markolaser also mark BLACK EFFECT as per customer demand?

Ans: Yes. Black marking on any substrate is possible you just need to send your sample.

10  What about service after the warranty?

Ans: Service after the warranty, is based on AMC or Per visit charge. The main advantage of having a Markolaser machine is – its after-sales service backup. We keep spares of all our machines for the next 10 years.
