Application heads for hot melt gluing

Application heads are the final link in hot melt gluing technology – this is where the adhesive is actually applied to the product. For the bond to be functional, clean and permanently strong, the application must be precise, consistent and matched to the specific application.

At Kaletech we supply application heads from the Swiss brand Robatech, covering a wide range of production needs:

• Jetting heads – for dot and bead application with extreme precision even at high speeds.
• Spray heads – for applying adhesive as a fine mist or spiral, ideal for uneven, porous or large surfaces.
• Coating heads – for an even, full-surface application, for example in laminating or bonding overlapping surfaces.
• Hand applicators – for flexible use in workshops, small-batch production or repairs.

Both pneumatic and electric application heads are available, enabling intermittent application – which significantly reduces adhesive consumption without compromising bond quality.

Our application heads handle a wide range of hot melt adhesives, including reactive polyurethane adhesives (PUR), thermoplastic EVA or PO adhesives, and pressure-sensitive adhesives (PSA). They are the ideal choice for demanding applications requiring reliability, flexibility and a long service life.

All Robatech application heads feature high reliability, low energy consumption and easy maintenance. They integrate easily into new and existing hot melt gluing systems – across different types of production lines and industries.
