The VJ Instruments table top Film Former coating machine is intended for development and small production of transdermal therapeutic delivery system laminates (TDS-patches) as well as to create edible films/ oral dissolvable film bulk were (EDF/ODF) without any further modification. It permits continuous coating of 150 mm wide webs with successive lamination.
The machine contain a coating head, where the coating knife is installed. This special tools guarantees an extreme high product quality with an ultimate accuracy of ±1% over the entire coating width and has therefore the lowest thickness variation available on the market.
The machine is built in a balcony manner with all the electric and other driving parts on the back of a 1400 x 540 mm big mounting plate. On the front of the plate the coating head, the winder shafts, the web guiding items, and the dryer cabin is mounted. The Temperature settings, the delivery rates of the pump and the web speed are adjustable on the top of the machine. Thus, all functions of the machine can be manipulated from the front side/ topside.
The substrate is coated onto a 3”diameter unwinder shaft mounted on the left side of the machine. From there, the web is pulled through the machine by the rewinder, situated on the right side of the machine. On its way through the machines, the web is at first guided around a coating roll onto which the knife is mounted. This knife spreads the desired fluid onto the passing –by web.
Immediately after the passage of the coating roll the web enters the dryer cabin. The web passes the dryer sliding across a stainless steel plate. This plate is electrically heated by resistive foils, which conductivity heat up the web from ambient room temperature (RT) to 90°C. the heating plate can be adjustable by a digital temperature controller on the top of the machine. The evaporated solvent are sucked away by ventilators fixed to the mounting plate in the rear of the dryer cabin. A lid covers the dryer zone. The drying process can be observed via the window inserted in the dryer lid.
Immediately after the web may be laminated with a protective, covering foil. This foil is unwound from a shaft at the right of the web rewinder and is pressed onto the passing-by web in the lamination station immediately at the dryer’s exit. The final laminate is then rewound by the rewinding shat at the machines lower right corner.
| Dimension (L x B x H) | 1435 mm x 645 mm x 700 mm(Approximately) |
| Weight | Approx. 300 kg, loaded |
| Accepted Web Width | The machine is made to be equipped with any web width ≤ 150mm |
| Coating Width | The maximum coating width is 120 mm |
| Max. coating speeds | The mechanical web speed is infinitively variable from 0.01 m/min to 3 m/min. During the coating process the speed needs to be slower to dry the wet film |
| Temperature Range | Room ambient temperature up to 90° C can be adjusted for the heated air in the dryer |
| Materials | All product touching parts are stainless steel or Aluminum |
| Power Supply | 230 Volts, 50...60Hz, 16 Amps secured |
| Coating system | The coating system is built up of an precise coating knife for coating width up to the maximum of 150 mm and can easily be reduced by Teflone strips to any width. The useable coating width is 150 mm for the maximum coating width of 120 mm with the below mentioned accuracy. The coating knife is fed with the coating solution by a precision tooth gear pump or peristaltic pump. |
| Coating Accuracy | The reachable accuracy is 1% |
| Ultra precise tooth | This ultra-precise tooth gear pump can be used for solution and dispersion |
| Gear pump | For fluid feed-in. The pump rate is visualised. |
| Winders | All winders (unwinder for carrier foil, unwinder for backing foil and rewinder for laminates) are with shafts for 3” |
