Spiral spray for laminating composite products
What’s spiral spray?

A state where spiral spray is applied

What’s spiral spray application?
A spraying method to apply adhesive to an object by discharging viscous liquid into a revolving air stream from a nozzle and forming fiber in spirals.
Wide application
Spiral spray is a stable non-contact application method for thin and wide application to laminate products.
The spiral can be formed at up to 60,000 rounds/min with the width of about φ15–20 mm.
The application method that follows the line speed realizes a beautiful spiral pattern with less overspray, whether the speed is high or low.

Working principle of spiral spray

Melted and pumped HMA is delivered to the gun module. The needle in the gun is raised by the operation air to deliver HMA in the gun to the nozzle and discharge it. The discharged HMA is extended in spirals by the air which is controlled to rotate to form fibers and reach the adherent.
