Numeric Inkjet Codeing Machine

Inks for bar coding, batch numbering, use-by date marking and other identification purposes are used in many industries especially pharmaceuticals and food. Viscosity is in the range of 2 to 30 centipoise. Formulation varies widely according to the method of application and end use.

A wide range of raw materials are used in ink formulations including resins, polymers, plasticizers, dyes, conductive salts and PR micronized pigments. These are supplied in powdered form, liquid form (i.e. predisposed in aqueous or organic solvent), and “chip” form. The following process requirements must be met: • The end product must be stable, homogeneous, completely agglomerate-free, and of a sub-micron particle size to prevent clogging of the ink jet nozzle. • Where applicable emissions must be minimized.

Futures:-
  • Dramatically reduced processing times
  • Rapid incorporation and wetting out of powders
  • The need for conventional milling cab be eliminated
  • Sorter proses time reduces solvent emissions
