Valco Melton Kube Series Melt-On-Demand Hot Melt Units
Valco Melton Kube series adhesive melters represent advanced, energy-efficient hot melt units engineered specifically for automated packaging lines, folding carton sealing, tray forming, and high-speed case erecting machinery.
The proprietary Melt-On-Demand technology melts adhesive granules strictly as required by production demand, eliminating tank charring, adhesive discoloration, viscosity breakdown, and nozzle plugging caused by prolonged thermal exposure.
The completely enclosed, monoblock melt reservoir protects virgin adhesive from ambient airborne contaminants, paper dust, and plant humidity, ensuring continuous dispensing at maximum line speeds.
Kube systems integrate an automated pneumatic pellet feeder that delivers adhesive directly from external bulk storage totes, removing manual replenishment and protecting plant operators from hot liquid surfaces.
Tanks 4, 8, 16 L, melting rate up to 14 kg/h, Melt-On-Demand design, up to 6 hoses.
Valco Melton EC Series Piston Pump Hot Melt Units
Valco Melton EC Series (Evolution C) melters deliver modern operational performance derived from the proven, robust Melton C platform.
Featuring high-output, double-acting pneumatic piston pumps, EC units maintain stable hydraulic adhesive pressure regardless of cycling speed variations, start-stop cycles, or line pauses.
Non-stick multi-layered Teflon-coated internal tank surfaces resist char accumulation and facilitate effortless cleaning during adhesive batch changeovers or scheduled line maintenance.
The multi-zone digital controller provides intuitive monitoring, individual hose and gun setpoints, and automated standby setback routines that prevent adhesive degradation during production breaks.
Valco Melton D and M Series Gear Pump Hot Melt Systems
Valco Melton D Series and high-capacity M Series gear-pump melters are designed for precision volumetric dispensing of high-viscosity hot melts, resins, pressure-sensitive polymers, and specialized adhesives.
Driven by variable-speed precision servo motors, the gear pumps ensure uniform mass flow output totally immune to fluctuations in nozzle head backpressure or adhesive viscosity shifts.
These heavy-duty systems are essential in continuous web lamination, corrugated box assembly, mattress manufacturing, nonwoven hygienic product bonding, air filter fabrication, and automotive interior assembly.
Modular manifold engineering supports single or independent dual gear pumps, giving engineers independent volume control across distinct dispensing zones.
Tanks from 4 to 180 L, single and dual precision gear pumps, servo motor drive, high-viscosity handling.
Valco Melton IsoMelt Series Airtight PUR Adhesive Melters
Valco Melton IsoMelt series adhesive systems are engineered specifically for the demanding processing of moisture-curing polyurethane (PUR) reactive hot melts.
The airtight melt enclosure maintains a continuous positive blanket of dry air or inert nitrogen, isolating reactive polymers from ambient moisture and preventing premature polymerization inside the tank.
IsoMelt systems deliver superior bonding strength, moisture impermeability, and elevated heat resistance for edgebanding, profile wrapping, and architectural sandwich panel manufacturing.
Melting occurs progressively across a heated lower grid plate while the unmolten PUR slug remains cool above, fully preserving the chemical integrity of the raw polymer.
For 2 kg and 20 kg PUR slugs, airtight inert nitrogen blanket, grid melting, moisture protection.
Valco Melton EPP-9 Piston and GP Gear Pumps
Genuine Valco Melton pumps deliver rock-solid hydraulic pressure and pulse-free adhesive flow into multi-port distribution manifolds.
The range includes EPP-9 double-acting pneumatic piston pumps with 6:1 and 14:1 pressure ratios for packaging applications, GP Series wear-resistant alloy gear pumps for continuous coating lines, and DD-1 double-diaphragm air pumps for water-based cold glues.
Heavy-duty construction, hardened tool steel gears, and tungsten-carbide sealing components deliver extended operating intervals in round-the-clock industrial service.
Factory rebuild kits containing pre-assembled piston packings, check valves, and hardened shafts ensure rapid turnaround during planned maintenance.
Valco Melton EcoStitch High-Speed Electric Hot Melt Valves
Valco Melton EcoStitch all-electric hot melt valves deliver breakthrough performance for high-speed dot-and-stitch adhesive dispensing. Engineered with zero dynamic seals or wearing friction rings, EcoStitch guns achieve service lives exceeding hundreds of millions of cycles without leaking.
By substituting solid adhesive beads with optimized micro-stitched patterns, EcoStitch cuts hot melt consumption by up to 75% while fully maintaining structural carton integrity and fiber-tearing bond strength.
MXM and ME modules communicate directly with MCP-4 and MCP-8 pattern controllers, enabling plug-and-play retrofits on existing case packers and cartoning machines.
Speeds up to 3000 cycles/min, zero dynamic seals, up to 75% glue savings, MXM and ME modules.
Valco Melton NC Series Pneumatic Hot Melt Applicators
Valco Melton NC Series pneumatic applicator heads represent the industrial benchmark for intermittent and continuous hot melt gluing in packaging, tray forming, and envelope converting.
Featuring positive air-open / air-close pneumatic actuation, NC modules achieve instantaneous, clean adhesive cut-off without stringing, tailing, or nozzle drooling.
The modular architecture accommodates custom manifold configurations from 1 to 8 or more dispensing modules with independent or shared triggering.
Integral in-line fluid filter cartridges guard internal orifices against rogue particulate contamination, protecting high-speed converting runs from unexpected shutdowns.
Air-open / air-close actuation, string-free cut-off, 1 to 8 module manifolds, Series 900 nozzles.
Valco Melton Heated Hoses and Precision Dispensing Nozzles
Valco Melton high-pressure heated hoses convey molten adhesive from melters to applicators without thermal gradients or degradation.
Constructed with multi-layered high-tensile steel wire braiding, heavy-duty thermal insulation, and integrated RTD Pt100 or Ni120 sensors, they guarantee precise temperature control throughout the fluid path.
High-precision Series 900 single- and multi-orifice nozzles, slot coating heads, and spiral spray nozzles ensure immaculate adhesive pattern repeatability and wear resistance.
With orifice diameters calibrated from 0.2 mm to 1.5 mm, systems handle micro-dot gluing up to full-width continuous web coatings.
Pressure ratings up to 100 bar, RTD Pt100/Ni120 sensors, lengths 0.6–7.2 m, nozzles 0.2 to 1.5 mm.
