Exploring the process of magni-lens doming at GMN

Versatile and durable, magni-lens doming is a clear two-part urethane development which when applied to a substrate, creates a self-healing dome that stands 0.06” (1.5mm) tall. The most unique feature of Magni-lens doming is that it functions as both a visual and performance enhancement. Visually, it adds richness and a depth of field to the graphics below, and from a performance standpoint, it can withstand the most extreme environments. 

Filmed at our Monroe, NC Division, our latest video will bring you a step closer to the Magni-lens technology. The video not only provides a glimpse into the process of creating the urethane dome, but also illustrates the broad spectrum of industries and products that have embraced magni-lens doming.

To initiate the doming process, the parts are staged on sheets so that they register precisely with the doming machine’s dispensing nozzles. As seen in the video, the dome is created with a nozzle or a hose that meters out a clear urethane coating. As the nozzle glides over the part, it dispenses the urethane polymer across the entire surface. The parts are always placed at a well-maintained distance from each other to avoid ruining the neighboring part in case of an overspill. While the featured Excel dryer part in the video has seven nozzles operating at once, different projects require different settings. Multiple nozzles correspond to the number of parts that are getting domed at a given time and the machine at GMN’s Monroe, NC Division has the capacity to operate up to 24 nozzles simultaneously.

After the urethane is dispensed, the part is inspected to ensure that the coating has traveled all the way up to the edges of the part. The viscus resin gradually “wets out” the entire surface and the part is placed on leveling pads to air dry. Although the coating starts to harden with the “skinning of the urethane surface” in about four hours, it technically takes about a week for the part to be completely cured. Selective doming can also be achieved by using a dam to contain the resin to a specific area. The entire process of Magni-lens doming is performed in a semi-clean room to mitigate dust and foreign particles from entering the water-clear dome.

The size of the part determines the amount of resin dispensed. Since parts come in varying sizes, each of them requires differing amounts of coating. The machine is uniquely programmed for every project, where it measures the length of the part to determine the space necessary between the parts in the set-up stage. Other elements such as the pour speed and the length to which the nozzle travels vertically above the part are also customized.  

The resulting magni-lens dome construction is extremely robust, chemical and moisture resistant, easy to clean and sanitize, and doesn’t deform with heat and fluctuating temperatures. Its versatility, functionality, and compatibility to adhere to a wide range of substrates including polycarbonate, polyester, vinyl, aluminum, and stainless steel, makes it a great choice for both indoor and outdoor applications. Seen widely in industries like automotive, appliances, electronics, and medical, the video will give you a glance into some of nameplates created by GMN over the past few decades.

Lensclad or thin-doming technology

Lensclad, also known as thin doming, is a proprietary solution by GMN that creates visually-striking and durable nameplates. Compatible with aluminum substrates, the process of Lensclad involves the application of a clear urethane topcoat that encapsulates the entire nameplate. The coating not only shields the nameplate from challenging conditions such as dust, gravel, temperature fluctuations, and humidity, but also adds significant scuff and mar resistance. It also acts as a lens, thus magnifying the underlying colors and features of the design.

Meeting at the crossroads of functionality and aesthetics, Lensclad is a self-healing technology. While all nameplates experience scratches, dents, or chip damage over time, this self-healing technology allows nameplates to absorb damages and restore itself back to its original form. The protective coating is formulated using UV inhibitors which helps it to stay clear and prevents it from yellowing. By enduring most of the “real world” harsh environments, Lensclad averts everyday wear and tear from deteriorating the overall quality of the nameplate.

Lensclad can be applied on flat or curved profiles, and embossed or debossed graphics, making it ideal for a diverse range of products and industries. The strength and durability of Lensclad doming enables the nameplate to withstand heavy impacts and corrosive environments. The technology also meets the rigorous requirements of automotive performance standards, making it a great choice for outdoor applications including cars, boats, and industrial equipment. Cosmetically speaking, Lensclad enhances the look of the nameplate, making it an equally great choice for indoor applications such as consumer goods, home appliances, cosmetic packaging, and car interiors.

Lensclad adds a thickness of 0.008” to the nameplate. This technology gives us the flexibility to vary the hardness of the urethane coating to fit the application. A thicker version of Lensclad, known as magni-lens, is also available, which adds a thickness of 0.060” to the nameplate. While the manufacturing process of magni-lens nameplates varies from that of Lensclad, it eventually offers the same functionality. For applying the thick doming, a nozzle filled with urethane coating applies the resin while moving across the surface of the nameplate. The resin gradually “wets out” the entire surface and dries over a period of 24 hours. The thickness of the nozzle head, the amount of resin it meters out, the direction in which the nozzle moves, and the time it takes to travel across the surface of the nameplate is customized and programmed for every unique application.

GMN has manufactured Lensclad nameplates for several well-known companies including Ford, MAC cosmetics, Honda, Excel dryers, and Estee Lauder to name a few. This performance-driven and cost-effective solution from GMN is truly a game-changer in elevating and preserving the look of your nameplates over time.
