In Can End manufacturing, lining compound, plastisol application and score repair play an integral role in the production of a quality product. Nordson’s complete line of dispensing equipment meets these applications needs with speed and efficiency.

Nordson Advanced Induction Systems are the most energy-efficient, non-NOx/COx generating dryers available for water-based compound. With Nordson nVision™ Tools, a computer modeling tool, you can evaluate various manufacturing parameters and compare energy costs with Nordson induction vs. hot air convection dryers. With nVision Tools, you can now make decisions based on hard dollars and cents comparisons.

Compound Lining

Compound applications apply material to the curled area of the can end, which cures into a rubberized gasket. This compound application creates a reliable seal between the can end and can body, minimizing the potential for leakage and preserving the integrity of the product.

Nordson systems use the compact reliable EcoLiner can end lining gun to apply the compound material as the end rotates. The gun features a zero-cavity, needle-and-seat designed nozzle for fast, clean cut-off. It also incorporates a detent adjust control for the very fine adjustments required in exacting end-lining operations.

Proprietary Nordson induction technology can be used to cure the can ends after the compound material is applied. Nordson dryers heat only the can end, not the air around it, providing more energy efficiency at reduced cost. The systems provide controllable, even heating without water-cooling.

Plastisol Application
 
The Nordson A11A can end lining gun can also be used for the application of plastisol to can ends. The plastisol is typically applied around a tab top to prevent micro-leakers and provide a safe edge around the scored area. Similar to compound application, the end is rotated as the gun applies the plastisol. Once the plastisol is applied, Nordson ovens can be used to cure the scored area.

Score Repair

Score repair applications are done on a variety of food and beverage containers that use the easy-open-ends. Nordson systems apply material to the scored area to prevent corrosion.

Based on the material characteristics, Nordson systems provide score repair using either the patented MEG® electric spray gun or the light-weight A10A-FC spray gun, or the pneummatic-operated A7A or an A7A airless spray gun. Material is supplied through an air-driven, dual-piston CP pumping system accompanied by high-pressure fluid filters and a fluid heater. The Nordson systems are used on all commercially available score repair spray machines.

The score repair system can also be equipped with the iTrax® spray monitor system to enhance overall performance.
