Our comprehensive line of Hoenle UV curing systems can significantly optimize the curing (hardening) of UV curable adhesives, coatings, and sealants.
Tangent Industries offers a comprehensive line of UV curing systems that can significantly optimize the curing or hardening of (photo-reactive) UV adhesives and coatings. Uniform UV intensity in a larger footprint facilitates curing multiple components in a batch process.
Measurement of UV intensity and dosage for spot and flood cure units, both LED and broad spectrum UV wavelengths. Hoenle LED curing equipment delivers high power for rapid production of Smart Cards and other high volume electronic glob top applications. Technical information on UV lamps, UV curing equipment, industrial safety products, testing instruments, ink and coating storage and handling materials, maintenance and printing supplies. Manufacturers still rely on traditional methods, but often enhance their systems with an LED light source.
The BlueWave LED DX-1000 can be configured to operate as either a small-area flood or spot-cure system.
Portable Loctite handheld LED devices do not require a controller, unlike standard systems. The LED Cube 100 chamber from Honle AG is available in wavelengths of 365, 385, 395 and 405 nanometers, It has a maximum irradiation intensity of up to 1 watt per cubic centimeter. The curing section of the OmniCure CV300 conveyor system features a center opening, into which is placed the OmniCure AC7150 or AC7300 LED light array. Medical device manufacturers frequently use spot curing for needle bonding and syringe-needle assembly. Consider, for example, their excitement nearly 15 years ago when suppliers of LEDs promised that this light source could cure UV adhesives more cost effectively than traditional bulbs (mercury arc, metal-halide, electrodeless). Today, wavelength mismatching rarely happens because manufacturers can now buy UV adhesives formulated specifically for use with LEDs.
To cure adhesive manually, the assembler places the wand tip close to the treated area and holds it for a second or two.
The wand is very flexible, enabling assemblers to quickly and accurately position, remove and reposition the light. However, spot curing large areas is much less cost-effective than using a flood, chamber or conveyor system.
Flood curing is recommended when curing large parts, many parts or many types of parts simultaneously. The light box, which limits the assembler’s exposure to UV rays, is mounted on the stand.
Another drawback of flood curing, according to Andy Scott, medical market application engineer for Henkel Corp., is it produces lots of stray lighting. Some suppliers offer focused-beam flood curing systems, which use reflectors to deliver a high-intensity beam of light to achieve maximum cure depth. Small chambers feature a single light and a 6-inch-square tray, whereas large units feature several lights and a tray up to 18 inches square. The LED Cube 100 from Honle AG is a compact UV irradiation chamber designed for bonding or potting components used in the electronics, optical or medical industries.
Because they require a fair amount of energy and floor space, conveyor curing systems are best suited for moderate to high-volume applications.
If belt speed is slow enough, one worker can load parts at the front of the conveyor and retrieve parts at the back.
UV-adhesive-curing systems present manufacturers with two ongoing challenges: optimize system performance and maintain it. Dell’Accio says step one is determining the lowest acceptable intensity (LAI) of light needed to fully cure the adhesive in the available cure time. Light intensity should be checked at the same time every day with a UV meter or radiometer, recommends Scott.
Monitoring intensity is especially necessary for systems with bulbs, which degrade slowly over time. Several medical device manufacturers closely monitor their curing operations with the AssureCure system from Henkel.
An operator places the LED light at one to four points along the adhesive bond line, and the detection unit optically measures the adhesive’s response during polymerization. Finally, manufacturers need to verify the presence and proper location of an adhesive on each part, and must make sure the adhesive is neither underexposed nor overexposed to UV light. Automated detection units feature an LED or other light source that illuminates the additive.

Signs of degradation include adhesive cracking, or a change in color or some physical property, such as increased hardness or decreased elongation.

Tangent Industries offers a broad line of Hoenle UV systems including LED curing equipment, UVAHAND (Hand Held UV curing equipment), Bluepoint (UV spot curing systems with light guide), UVASPOT (large area UV curing equipment) and more! Please contact Tangent for more information about the products, including pricing and availability. In flood mode, the system delivers up to 1 watt per cubic centimeter over a 1-by-1.5-inch area.
The units can be hand operated or fixtured, and they deliver light irradiance of 2.5 to 3 watts per cubic centimeter at a wavelength from 390 to 420 nanometers. Manufacturers were also told that LEDs last longer, generate less heat and can be used in more flexible configurations than bulbs. This advancement in adhesive chemistry helps manufacturers obtain all of the promised benefits of LEDs. These systems usually feature a controller with attached tubes (called light guides or wands). For automated applications, extended-length wands are mounted just above the conveyor to ensure precise placement of the narrow light on the treated area. Spot curing is also great for gasket forming because it allows the assembler to move the wand in any direction around a part or adhesive bead. Another limitation is each part needs to be held securely or fixtured prior to light being applied. The units run on rechargeable batteries or AC power, can be hand operated or fixtured, and feature an internal cooling fan. System components include a controller (to set irradiance and duration), a light box or LED array, a stand, and a cable to connect the controller and light.
For manual applications, parts are placed below the light box, and the controller is turned on by hand or activated by a foot switch. Medical device manufacturers find the method very effective when curing catheters and cylindrical parts.
Although invisible, UV light can be harmful to skin, so manufacturers need to insure worker safety around affected areas. The beam measures either 1 by 4 or 1 by 6 inches and has an irradiance of up to 350 watts per cubic centimeter. Cure time ranges from 1 second to several minutes, depending on adhesive and part size or volume. Automatic shutter control protects operators from UV exposure during tray loading and unloading. It is available in wavelengths of 365, 385, 395 and 405 nanometers, and has a maximum irradiation intensity of up to 1 watt per cubic centimeter. A typical system’s conveyor is about 12 inches wide, several feet long and mounted on a platform. Bulbs stay on continuously during operation, but LEDs are triggered on when a part is in position for curing. Depending on application, the array is either positioned perpendicular to the belt’s direction of travel, or in 15-degree steps until it is parallel to the belt.
Travel speed of the Teflon-coated fiberglass belt can be set from 3 to 48 fpm in 1-foot increments.

LAI is always application specific and involves curing parts at various intensities and testing them to customer performance requirements. If an adhesive is not detected, the system notifies the operator via a workstation PC or PLC.
Dell’Accio says double or even triple exposure (two to three times the dosage required to cure) usually produces no adverse effect on adhesives, including those from Dymax.
Before joining ASSEMBLY, Camillo was the editor of PM Engineer, Association for Facilities Engineering Journal and Milling Journal. After another successful event in 2015, we are looking forward to bringing back this exclusively assembly focused tradeshow for another incredible year! Unlike competitora€™s units, the INTELLI-RAY integrates all system components into a small lamp head which can be easily mounted anywhere on a factory floor, with virtually no cabling or remote control boxes required. The systema€™s LCD display and digital keypad make programming and monitoring of curing operations a snap. The exposure timer also has a user controlled manual mode in which exposure time increments on the display to indicate elapsed time of a cure. Application Engineering at Tangent Industries provides assistance with adhesive and coating recommendations, and will assist to optimize your UV curing process for maximum productivity and efficiency. After the assembler sets light irradiance (watts per cubic centimeter) and duration (seconds) on the controller, the light is turned on.
Light projects downward and, within a few seconds, cures parts positioned in an area of 4, 5 or 8 inches square. The chamber is controlled by a built-in timer and can be operated in a continuous or timed mode.
Once LAI is determined, he suggests building in some additional margin by increasing either the cure time or intensity by 50 percent. Introduced in 2012, the system includes adhesives, an LED light source, a detection unit and software. For those applications, specialty and custom optics are required to precisely apply light to the part. Manual detection involves shining a black light on the part, causing a blue or red area to appear in the part and verify adhesive is present. However, exposure beyond this level will degrade any UV adhesive and some substrates, especially plastics. Our event mission and commitment to you remains the same - helping suppliers, buyers and users of assembly equipment in manufacturing plants connect, learn, share and explore all things "assembly".
A second timer is used to display the age of the lamp in hours, and triggers a panel-mounted light to warn the user when the lamp should be replaced.a€? Lamp Intensity ControlThe system has a user adjustable intensity level. A Windowsa„? compatible graphical interface program allows all systemfunctions to be exercised (see photo), and with RS485, multiple units can be networked.a€? Foot pedal controlAn optional shutter control foot pedal is available for applications requiring hands-free operation. If you reside in an EU member state besides UK, import VAT on this purchase is not recoverable. Hoenle is a recognized leader in the global development of UV technology for industrial applications.
Low- or high-intensity light passes through the tube, which has a lens at the tip, at a diameter of 5 to 12 millimeters.
For automated applications, the controller is integrated into the production line, and parts are conveyed under a mounted light box. In spot mode, one or several light guides can be installed into an optional adapter to cure tiny areas with up to 15 watts per cubic centimeter.
This feature provides the flexibility of choosing appropriate curing intensity for sensitive materials.a€? Standby modeThe unit automatically reduces lamp power by one half when the shutter is closed. The pedal can be used in conjunction with the systems exposure timer, or in a manual mode in which the shutter remains open as long as the pedal is pressed.a€? Lamp power regulationThe systema€™s switch mode power supply maintains constant lamp power regardless of variations in AC line input or lamp voltages. Hoenle products are used worldwide in the manufacture of electronics, microelectronics, optics, medical devices, furniture, and glass art.
The company also recently introduced a high-intensity LED flood with a 5-by-5-inch active area.
This reduces excessive heat and therefore increases life of system components, without the need to power down.
