Spray Coating Equipment

Spray Coating Equipment applies hot melt adhesive in a fine, controlled spray pattern onto material webs in hygiene product production. Uniform spray coverage with minimum glue consumption is essential for product quality and manufacturing cost control — adhesive is one of the highest-cost consumables on a diaper line.

Precision Hot Melt Application

The hot melt spray coating machine uses precision metering pumps, heated hoses, and multi-nozzle spray heads to apply adhesive in patterns ranging from full-width coating to narrow elastic-attachment lines. Modern systems feature individual nozzle control, allowing different spray patterns at different stations. Automatic gap adjustment maintains consistent spray width regardless of line speed changes. Typical glue savings from upgrading to a modern spray system are 10-25% compared to older equipment.
