UV Led curing In Medical And UV LED Sterilization Applications


Processes must be dependable, consistent, and able to be evaluated when manufacturing a medical device. UV Led curing adhesives meet these requirements well for bonding pieces.

They are single-part systems with various viscosities that allow for precise, repeatable dosing of substances in both quantity and location. A controlled process window and instantaneously completing the UV Led curing process allow for fast online quality assurance (QA) tests. A robust technique must comprehend and manage process variations as the sector requires.

The Advantages Of UV Led Curing

For many years, broad-spectrum UV light produced by mercury-based arc lamps was the primary source of light used to achieve UV Led curing. With their recent technology and other advantages over broad-spectrum lamps, LED-based UV lamps are becoming increasingly popular.

Traditional arc-based lights have warm-up and cool-down times. Thus, they are typically left on for the duration of a shift with mechanical shutters controlling the exposure. Instant on-off capabilities of LED-based UV lamps allow them only to turn on, when necessary, consume significantly less power, and have no mechanical components.

They don't require bulb replacement and produce less heat, enabling UV Led manufacturers to use more delicate substrates.

The fact that LED UV lights have a remarkably constant intensity output over time is of particular importance to producers of medical devices. Frequent UV brightness measurements (using a radiometer) are needed to maintain a proven minimal UV Led curing dosage, and either the bulb is frequently changed, or a manufacturing modification is performed.

Broad-spectrum Ultraviolet arc lamps' output degrades dramatically with time. These process issues are avoided by adopting a steady, LED-based UV lamp, eliminating a problematic manufacturing variable.

Selecting The Proper Adhesive

Modern adhesives are developed to cure with LED's distinctive narrow spectrum output in tandem with the adoption of UV Led curing lamps. LED-curable Adhesives will respond to the constrained spectrum of wavelengths to provide the required and anticipated cured characteristics.

If an adhesive is not designed to be cured with LED, its cured qualities may differ from those listed in the datasheet. Therefore, this may not be the situation with those materials. Coursework on parts and components will be required in both situations.

UV Led manufacturers should consider using adhesives that have passed USP Class VI or ISO 10993 testing, which certifies they are non-toxic. The adhesive must also withstand the necessary sterilizing procedure, such as ethylene oxide (ETO).

Various UV-curable adhesives that can tolerate UV LED Sterilization are available from Intertronics and have passed ISO 10993 testing. By choosing one of these compatible adhesives, the gadget will be more likely to pass later toxicity tests.

The substrate will determine the glue to use; an adhesive that sticks well to PVC, for example, may not attach well to stainless. As some fewer common plastics, like polyether ether ketone, are employed in the manufacture of medical devices, it may be even more difficult to ensure adequate adhesion to all the substrates (PEEK).

A capable provider will be knowledgeable about substrates unique to the industry and will have suitable adhesives available for testing. In some circumstances, plasma surface treatment can enhance the adhesion of low surface energy polymers.

UV Led manufacturers of medical devices can benefit from the accelerated inspection, and quality assurance (QA) made possible by the extremely quick UV Led curing adhesives, either during production or at the end of the line. Some formulations can change color when cured, turning transparent or another color. Another helpful inspection trait is strong red- or blue fluorescence under black light.

Selecting The Appropriate UV Curing System

UV Led curing lights based on LEDs are easily accessible in wavelengths that work (between 365nm and 405nm) and with power levels adequate even for high-speed production. They can be hand-held, benchtop-mounted, or created for use in robotics or conveyors, and range from lamps producing small spots with a few millimeters in diameter to vast area floods. They outperform their broad-spectrum arc light predecessors thanks to their high-intensity spot lamps, which can produce UV Led curing light at a rate of over 30W/cm2.

Variability or inconsistency is not acceptable in the production of medical devices. Adhesives made to be cured using UV light produced by UV Led curing lights can help your production achieve consistent and reliable bonding.

UV Technology

The thermal oven drying technique, or a currently manual process is typically replaced with UV Led curing. Automated UV Led curing techniques can significantly enhance most medical manufacturing procedures where accuracy, consistency, and quality are crucial factors. Here is a quick rundown of the UV Led curing technology on the market and its benefits and drawbacks for most medical uses. The light head, or irradiator, of conventional UV Led curing systems, houses the bulb and reflector.

A power supply, also known as a ballast, linked to the light head by electrical cables, controls the lamp head. A cooling system, such as a blower or cool water, is also present to regulate bulb temperatures because the lamp head needs to be cooled for proper functioning. A more recent development is the availability of UV Led curing systems, which have the added advantages of extended life and a compact design for simple integration into the already-existing coating, painting, and marking machinery.

The chemistry, general process design, and maintenance concerns will determine the kind of UV Led curing apparatus, the bulb type, and the part's orientation. For an effective, thorough cure, many medical adhesives work best when exposed to long wavelength iron or metal halide additives (350–430 nm, sometimes known as "D" or "V" type bulbs).
