UV Ink Curing Lamps

in

The process of UV ink curing has been around since the 1960’s and uses high intensity ultraviolet light to create a photochemical reaction. By using the proper intensity of UV wavelengths, a byproduct is produced that hardens resin and dries inks. It offers numerous advantages over traditional heat-cured systems and has become the method of choice for many as it safely and cost-efficiently cures inks, as well as adhesives, coatings, varnishes, decorative glazes and lacquers.

Industrial UV Air System Technology and Applications

in

OEMs across the globe utilize industrial UV air systems due to an increasing awareness of the importance of protecting our environment and the consequences when we do not. Clean air is at the front and center of those concerns and today’s advanced industrial UV air systems provide a broad range of industries with the perfect solution. By safely purifying and destroying harmful chemicals from the air as well as eliminating offensive odors, industrial UV air systems deliver economic, environmental, and human benefits.

UV Germicidal Technology

Scientists have been studying the effect of UV light as a method for interrupting the transmission of airborne pathogens for well over a century. In 1877, two English scientists, Downes and Blunt, discovered that sunlight kills bacteria. Their studies showed that sugar water placed on a shaded windowsill became cloudy while a similar solution in direct sunlight remained clear. When examining the two jars, “they realized that bacteria were growing in the shaded solution but not in the one exposed to sunlight.”

The two men later found it is the shorter spectrum of UV light that kills bacteria and effectiveness is dependent on the amount and duration of light. Today we know that for a UV air system to effectively kill and render microorganisms unable to reproduce it requires prolonged exposure as well as a specific intensity and wavelength of UV radiation.

Germicidal Lamp Applications

Germicidal UVC lamps provide industries a way to disinfect and improve the quality of air in the workplace and the immediate environment without the need for toxic chemicals that are not only harmful to humans but the environment as well. Furthermore, UVC lamps are simple to operate and maintain and help industries to comply with strict local codes and national regulations. For industries such as food processing plants, farms, commercial kitchens (HVAC), kennels, and wastewater plants, odor control is important to not only the employees but to those that must work or live around the plant.

UV Polymer Curing

in

UV Polymer curing is a process that uses UV light to alter the properties of a polymer, or photopolymer.  A photopolymer is the term for a polymer that responds to UV light, which is basically invisible electromagnetic radiation.  When a photopolymer, which can be a variety of resins, is exposed to the UV radiation, it will typically harden and seal, creating a strengthened surface or an unbreakable bond.

UV Polymer Curing Applications

UV Polymer curing is used in many industrial applications to instantly dry ink or to create a hardened surface without use of solvents or chemicals.  Some common examples of useful applications include:

  • Adhesive Bonding

  • Inks / Varnishes / Lacquers

  • Decorative Glazes

  • Coatings

  • Label Printing

  • Graphic Designs

  • Disinfection of Medical Equipment

These are just a few of the many industries that are using UV lamps for curing various polymers.  There are many additional applications for UV curing, and more and more businesses are seeing the benefit of this process.  UV curing was first introduced in the 1960’s, and it is increasingly being adopted by companies as there are many advantages over prior methods of curing polymers.

Curing Lamps

There are three types of UV lamps used for UV polymer curing.  High Pressure UV (HPUV), Medium Pressure UV (MPUV), and Amalgam Lamps.  High Pressure (HPUV) curing lamps are also referred to as Metal Halide lamps, and use mercury with short wavelength outputs.  The HPUV lamps are typically used for the altering of polymers by hardening resins in many of the applications mentioned above.  Medium Pressure lamps (MPUV) are often used for water and air disinfection purposes, while Low Pressure Amalgam lamps are typically used for curing catatonic inks which are inks that are typically an epoxy based resin and respond to UV lighting.  LightSources and our European partner, LightTech, are proud to have pioneered new pellet technology for amalgam lamps.

There are so many benefits to using UV lights for curing it will be difficult to list them all.  We can begin with efficiency.  Imagine a conveyor belt full of parts passing under a UV light as they head to their next destination, possibly quality inspection or packaging.  While no one touched the parts, sprayed solvents on them, or even laid eyes upon them, they underwent a very important process.  Just by passing under the lights, the surface was hardened and strengthened, a strong scratch-resistance texture was enhanced, and any printing or graphic design needing reinforcement was just instantly dried and strengthened.

Now imagine a different manufacturer that does not use UV curing.  They must have an assembly line with people spraying solvents on the parts, requiring face masks and ventilation and still exposing the employees to harmful chemicals in the air and on the skin.  This also opens the door for human error, uneven coating, and inconsistency.

As you can clearly see from these two examples, the efficiency of UV curing is definitely one of the most valuable benefits.  This efficiency also leads to increased production speeds as several parts can be treated at once simply by passing under a row of the proper high intensity UV lighting.   Choosing to cure your parts with UV lighting will increase your output dramatically, while not requiring an investment in an increased labor force, workstation for an added process, or supplies of chemicals that are most likely harmful to the environment.

In addition to efficiency and cost savings, consistency is another big advantage of using UV curing over any other process.  With UV lighting, the amount of exposure is constant, and consistent.  There is no chance of human error in applying an outer coating unevenly on a large amount of parts.  This consistent process results in less quality issues such as internal rejects and the worst rejects of all, customer returns and complaints.   A consistent process is something that all quality minded OEM’s are searching for as consistency results in superior quality, time and again.

Efficiency and consistency are and should always be a top consideration for any production process, (both result in increased profits), but let’s not forget an even more important benefit – the health and safety of your workers and the environment.  Simply by using UV radiation to cure your parts, you are saving your employees from inhaling harmful chemicals, you are not emitting pollutants into the air, and you also do not have to worry about properly storing or disposing of such harmful chemicals.   Any chemical substance on a worksite must be handled with proper storage and disposal guidelines, while maintaining material safety data sheets on the chemical or solvent.

Not only does the increased efficiency and consistency provide an instant return on your investment and a quick increase to the bottom line, not purchasing, storing, disposing of or documenting alternative substances is also a huge savings, and instant increase in profitability.

With all of these benefits, it is difficult to imagine why a manufacturer would choose an alternative method over UV polymer curing.   Efficiency, consistency, safety, less regulations, increased profits, and last but not least – longevity.   LightSources UV curing bulbs will retain their energy output up to 90% of their end of life cycle, enhancing and prolonging all other financial benefits.  As we all know, time is money.  Less time spent processing parts, or replacing bulbs, is an immediate increased profit.
