On high-speed lines like the BT Coating I module, UV varnishes enable dramatically faster production. That’s because it can be cured instantaneously using infrared heat and UV lamps, minimizing the usage of VOC.

Constructed around a central rotary dial, the BT Coating I module rotates 3D parts past up to four stations inside the module for spraying, IR baking and UV curing.It’s a super-fast, super-efficient form of finishing with no waiting time. Besides speed, there are other major advantages of the BT Coating I module, compared to traditional varnishing lines. There is a HD camera for checking for flaws, ensuring consistent quality control. There is also no batch system, so testing and setup can be done very quickly.

The BT Coating I module comes with up to four different stations:

Automated spray booth
The parts rotate inside the booth while the guns remain static. The number of guns can be customised according to your needs. Spray types include Electrostatic, HVLP, Airless. It can spray any type of UV varnish.

IR flash-off oven
Quick drying system for evaporating the volatile elements in the varnish. Avoids bubbling and leaves a long-lasting, stable surface.

UV lamp curing
UV lamp cures the varnish by initiate a photochemical reaction to fix polymers. Utilizing ‘Cold Cure’ UV systems made by Tapematic, reduces the stress on the object from typical UV lamps which could distort and strees the substrate.

Hi-spec quality inspection
HD camera-based optical inspection can be integrated together with special sampling software. This allows the machine to inspect and grade every part instantaneously. It can check for consistency in the coating and spot even microscopic manufacturing flaws in shape, coating or imperfections. All without any operator presence or intervention.
