Vibration technology for viscosity control
Gama recently presented new solutions of control process systems VIS G29 and G28, with measurement “vibration” technology for the viscosity control of inks, together with the G90 for temperature control and the G50 for the pH control. The new innovative systems VIS G20 for the viscosity control of inks, VIS G30 for adhesives and varnishes, and VIS G31 for the pH control. These systems benefit from the same innovative features as the previous ones:
- Easy to use
- Lack of mechanical parts subject to constant wear
- Reduced maintenance
- Integration into the conduit for sending ink to the press
- Compliance with antiexplosion standards
- Energy saving
- Low environmental impact
The new G20 system allows the control of the viscosity of solvent-based inks and, if necessary, automatically makes corrections by means of the addition of solvent for accurate print quality and to obtain the maximum performance of the Flexographic or Gravure presses. The system communicates information to the operator in real time and issues a report at the end of the production. The operator can save set-up and “Jobs” parameters for future reprints. It is ideal for 1 to 6 colours printing presses, with the possibility of managing it by a single colour LCD keyboard or PC.
The VISG20 can be integrated with the G90 ink temperature control system to obtain a stability of temperature, with recommended values between 22°-25°, and to reduce the
generation of foam for an excellent qualitative yield during the printing process.
The VIS G30 is a viscosity and temperature control system for solvent-based and water-based varnishes and adhesives. The G30 can be installed on an element of Flexographic or Gravure printing press or on a laminator. Easy to use and to set, the G30 can be managed by a PC, as integral part of an ink control system, or through a LCD keyboard.
Valves are provided to keep any formation of dirt out of the measurement area and out of the sensor, making sure the viscometer stays clean.
