APPLICATIONS IN MODERN MANUFACTURING PRINTING PRINTING BONDING BONDING GLUING GLUING COATING COATING CLEANING CLEANING AcXys SOLUTIONS

PRINTING LABELS Plasma activates the label improving printing quality Plasma activates the label improving printing quality Ink droplets spread and adhere strongly to the label after drying

TUBING Plasma activates the outer surface of the plastic pipe before printing Plasma increases surface energy

BONDING / GLUING The highly reactive stream of chemical species generated in the plasma has 2 actions: The highly reactive stream of chemical species generated in the plasma has 2 actions: – Surface energy is increased – Surface oxidation makes strong chemical bonds Parts assembly is exceptionally strong Parts assembly is exceptionally strong

FAILURE ANALYSIS Lap shear test reveals failure mechanisms (i.e. ASTM D1002) Lap shear test reveals failure mechanisms (i.e. ASTM D1002) Adhesive failureCohesive failure GLUE 1. Sample preparation NO PREPARATIONPLASMA TREATMENT 1200 psi 70 psi

BOND PROPERTIES Plasma surface treatment produces bonds often stronger than other methods using solvents and abrasives. Plasma surface treatment produces bonds often stronger than other methods using solvents and abrasives. The adhesive specifications define the bond strength. The adhesive specifications define the bond strength.

COATINGS AcXys plasma sources can be used for the deposition of coatings materials AcXys plasma sources can be used for the deposition of coatings materials For example, high speed deposition of glassy films over polymers is feasible For example, high speed deposition of glassy films over polymers is feasible

CLEANING Plasma treatment creates ultra- clean surfaces Plasma treatment creates ultra- clean surfaces Plasma cleaning removes what solvents leave on a material’s surface Plasma cleaning removes what solvents leave on a material’s surface Plasma cleaning can kill bacteria Plasma cleaning can kill bacteria
