VOLTA HOT MELT JETTING HEAD FOR HIGH PROCESS RELIABILITY

The Volta electric hot melt jetting head ensures high process reliability for dot and bead application of thermoplastic adhesives. It is resistant due to its design and protected against external influences with protection class IP55. Thanks to its high switching frequency, Volta is suitable for adhesive-saving hot melt stitching. With this application head, you save both adhesive and energy - and thus operating costs.

ADVANTAGES OF VOLTA AT A GLANCE

  • Electric application head for high process reliability. Low-maintenance and resistant
  • 60 % less energy consumption than the SX pneumatic application head
  • Up to 40 % adhesive savings with hot melt stitching
  • Straightforward system integration via 24-VDC connection without a booster
  • 1 billion operating cycles with consistent adhesive application precision
  • CoolTouch insulation protects personnel from burns, is gentle on heat-sensitive products, and reduces energy consumption

VOLTA BRINGS STABILITY TO THE ADHESIVE APPLICATION

Volta is an electric application head that delivers reliable adhesive application over the course of 1 billion operating cycles. It requires little maintenance as it does not have any dynamic seals. Its compact steel and aluminum design also makes it durable. Volta complies with protection class IP55, which means that it is protected against external influences such as jet water or cardboard dust. Therefore, this application head is suitable for harsh environments, such as those found in the packaging industry, as well as for the food or pharmaceutical industry.

SAVE 60 % ENERGY WITH VOLTA

The Volta hot melt jetting head is an economical application head in several ways that can result in a quick return on investment. Compared to the SX pneumatic application head, Volta achieves energy savings of approx. 60 %. This is because the electric application head does not require compressed air. This reduces operating costs because compressed air systems are high-maintenance and expensive to operate. Volta can be easily integrated into new and existing systems. The remote electronic module with a 24 VDC interface enables direct control without a booster.

Volta is suitable for hot melt stitching thanks to a switching frequency of 200 Hz and 1 billion operating cycles. Dot application replaces bead application in this process. Compared to bead application, stitching can save up to 40 % of adhesive. Since the application head does not require compressed air, it is pleasantly quiet at 60 dB(A). Another advantage over pneumatic application heads is the low wear despite high switching frequencies. This reduces maintenance work to a minimum.

PRECISE DOT AND BEAD APPLICATION EVEN AT HIGH SWITCHING FREQUENCIES

Thanks to the electric drive with a switching frequency of 200 Hz, the Volta hot melt jetting head produces a precise and repeatable adhesive application with an exact cut-off. This ensures process stability. Volta achieves excellent application quality also thanks to the uniform temperature distribution in the application head. In addition, an innovative insulation protects the nozzle from drafts. This ensures consistent adhesive viscosity right up to the nozzle.

The integrated adhesive filter in the heating block reduces nozzle clogging and thus downtime. To ensure that the adhesive amount remains consistent over the entire service life of the application head, the stroke can be adjusted manually if required.

COOLTOUCH: PROTECTION FOR OPERATING PERSONNEL AND PRODUCTS

The Volta hot melt jetting head is completely equipped with a CoolTouch insulation as standard, also for multiple application heads. Volta also features a green touch protection on the bracket. The CoolTouch insulation protects operating personnel from burns in the event of accidental contact. Thanks to reduced heat radiation, even heat-sensitive products, such as chocolate or medicines, are protected during adhesive application.
