Vastex PTF-COMBO-100 Powder-to-Film Coating System with integral D-100 Conveyor Dryer.
The PTF-100 Powder-To-Film system (patent pending), also known as a Powder Shaker, uniformly coats DTF films with adhesive powder, improving DTF printing performance and operator safety. Instead of hand-coating DTF films in open plastic containers that expose shop personnel to adhesive dust and require operator time and attention to obtain reliable results, the PTF-100 system provides uniform coverage without dusting and spillage, reducing waste and freeing staff to optimize production time.
Purpose-built for DTF printing, the tabletop unit consists of a steel case on a stand, with a clear polycarbonate door set at an angle. It comes with two identical cartridges, each of which can hold approximately 3 lbs (1.4 kg) of adhesive powder. It has a rear mounted exhaust designed to collect adhesive dust particles and create a "negative pressure" condition within the cabinet. The film tray is suspended on special rubber hangers that isolate it from the intense vibration applied to remove excess powder from the film.
To operate, a filled cartridge is inserted at the top of the unit, and an empty cartridge at the bottom. An operator positions the wet DTF printed film on the application tray, print side up. Once the polycarbonate door is closed tightly, the operator adjusts the position of the powder deflector to accommodate the size of film being coated.
An adjustable timer allows the operator to adjust the duration of vibration, achieving repeatable results. To initiate a cycle, the user pushes up a lever to release the desired amount of powder, then pulls the same lever down to start the timer/
vibration. The top cartridge releases adhesive powder, which rains down on the film, ensuring complete and even coverage. When empty, the upper cartridge can be switched quickly and cleanly with the lower cartridge containing all excess powder, reducing exposure while eliminating waste and allowing continuous production until refilling is needed.
