UV LED spot curing lamp offers ‘super-fast’ cures
Provided with a separate, compact light emitter, suitable for benchtop use but small enough to be readily integrated into robotic or other fully automated systems, the Dymax BlueWave MX-150 LED UV spot curing lamp has been unveiled by Intertronics.
There are two main parts, a controller with a touchscreen interface, and the high-intensity UV LED emitter. The modular unit is designed to offer higher, more consistent UV curing intensities than traditional spot-curing systems – up to 40W/cm² at wavelengths of 365, 385 or 405nm. The high curing energy is created using an LED chip in the emitter, located close to the point of cure. The lightguide, which can compromise cure intensity, is optional, and the emitter can be mounted away from the controller without loss of energy, says the company.
The unit is compatible with a variety of UV and visible light-curable materials, including adhesives, electronics encapsulants and coatings, and temporary masking products. Instant on-off capability saves energy and eliminates the need for warm-up periods. The curing profile can be optimised to protect heat-sensitive substrates.
The unit can be activated by a foot pedal, its touchscreen, or through a PLC interface.
