Laser Marking Q&A

How many marks can I get from 500 grams of LMM-6000 & LMM-14?

BEHost 0 320

Question- How many marks can I get from 500 grams of LMM-6000 & LMM-14?

Answer- When thinned and used as recommended, 500 grams LMM-6000 & LMM-14 should provide approximately 6000 square inches of coverage. The number of marks you can make will depend on the size of the mark and how much material you apply to the substrate.

Will LMM-6000 & LMM-14 work on anodized metals?

BEHost 0 432

Question- Will LMM-6000 & LMM-14 work on anodized metals?

Answer- LMM-6000& LMM-14 has generally been found to not work on anodized metals, but in some cases satisfactory results have been reported. We recommend experimentation if possible to determine if LMM-6000 & LMM-14 will work in your particular application. The CerMark LMM-6904 is formulated for use on anodized surfaces.

Will LMM-6000 & LMM-14 work on coated metals?

BEHost 0 341

Question- Will LMM-6000 & LMM-14 work on coated metals?

Answer- No. If the metal has a protective coating on it, the coating must be removed before it can be marked. The protective coating will interfere with LMM-6000 & LMM-14 ability to bond to the surface of the metal.

Does LMM-6000 & LMM-14 work on glass?

Question- Does LMM-6000 & LMM-14 work on glass?

Answer- No. The LMM-6000 & LMM-14 are not formulated to be used on glass surfaces. It is designed to work only on metal surfaces. CerMark also offers the LMC series products for laser marking on glass and ceramic substrates.

How much power should I use?

BEHost 0 335

Question- How much power should I use?

Answer- The power settings that LMM-6000 & LMM-14 will work best at vary depending on the laser being used. For example, with a 35 watt CO2 laser, marking on stainless steel requires the use of 100% power at a write speed of 4-8 inches per second. Marking on aluminum requires 100% power at a write speed of 1-4 inches per second with the same laser. A more powerful laser will be able to make the same mark using less power or writing faster. Also, aluminum, copper, brass and other soft, heat conductive metals require higher powers and slower writing speeds. These metals will conduct heat away from the marking area faster than steel, thus requiring more heat (power) to make a mark. Your power settings will vary depending on the laser used and the substrate being marked, so some experimentation may be necessary to achieve the best mark.

What kind of laser do I need?

Question- What kind of laser do I need?

Answer- LMM-6000 & LMM-14 can be used with CO2, YAG, YVO4, or Fiber laser marking systems. When using YAG, YVO4 and Fiber laser systems a continuous wave system is recommended. Some pulse systems may work, this depends on the frequency rate capabilities within the system.

Can I reuse LMM-6000 & LMM-14?

BEHost 0 369

Question- Can I reuse LMM-6000 & LMM-14?

Answer- LMM-6000 & LMM-14 should not be used if it has dried out. LMM-6000 & LMM-14 also should not be reused by washing it off of a part then respraying the washed off material. Reused LMM-6000 & LMM-14 will not produce a high quality mark. Performance characteristics will also be affected.

How long will the marks last? How tough are they?

BEHost 0 320

Question- How long will the marks last? How tough are they?

Answer- Marks made using LMM-6000 & LMM-14 are permanent. Marks made with LMM-6000 & LMM-14 are generally considered to be as tough as the metal they are applied on. Physical testing has shown them to be resistant to many common strong acids, bases, organic solvents and extreme heat or cold. LMM-6000 & LMM-14 also have good salt spray resistance, scratch resistance and QUV resistance.

What metals does LMM-6000 & LMM-14 work on?

BEHost 0 348

Question- What metals does LMM-6000 & LMM-14 work on?

Answer- LMM-6000 & LMM-14 has been tested on stainless steel, aluminum, brass, copper, nickel, silver, and titanium. LMM-6000 & LMM-14 will not work on metals that have a coating or protective clear lacquer.
