Hot Melt News

Erecting and sealing cases, cartons and boxes with hot melt adhesive is standard practice in the packaging industry. This is usually accomplished by spreading hot melt over case flaps in a series of parallel beads. Using smaller parallel beads on close centers bonds much faster than using a large bead or two. These smaller beads also offer a much stronger lamination bond, rather than the less effective point of contact bond.

“T” nozzles, or spreader nozzles, have been used as a low cost method of channeling hot melt into multiple patterns from one applicator. Hot melt adhesive flows under pressure into this “T” or spreader nozzle and is channeled into a series openings on close centers. The “T” nozzle or spreader nozzle is used with hot melt stick guns, hot melt bulk guns as well as automatic hot melt guns.

The “T” nozzle is not suitable for precise application requirements, as there can be a tendency for temperature variations within the nozzle. The “T” nozzle is much larger than a standard nozzle, so the adhesive temperature varies as it moves through the nozzle and further from the heat source. This can create poor patterning and hot melt stringing. The use of low viscosity
hot melt will result in better flow from the “T” nozzle.

Frequent and consistent use of the gun and nozzle, will also improve patterning, as the hot melt flow through the nozzle actually heats the nozzle making for more consistent temperatures from gun to substrate.

Nordson Corporation®* offers quality hot melt machinery and components to manufacturing companies worldwide.

For many years, Nordson®competitors have offered /second rate/low quality/ replacement hoses, guns, and nozzles to retrofit Nordson® tanks. These components, while not offering the performance of the Nordson® parts, were often purchased because of their lower sales price.

Many Nordson® hot melt equipment customers have realized that production losses due to lesser performance replacement components is not worth the up front savings on these components and have returned to purchasing the Nordson® manufactured components.

This industry shift back to original Nordson® hot melt equipment components has forced a select few competitors producing Nordson® replacement components to dramatically improve component quality.

Lower cost quality Nordson® compatible tanks, hoses, guns, modules and nozzles are are now available and provide long operational life at much lower prices.

Some of the key features to look for are as follow:

1. Does the company supplying Nordson® hot melt parts offer a complete Nordson replacement system that is compatible with your current Nordson® hot melt system?
2. Do the Nordson® replacement parts retrofit directly to the Nordson® systems in your plant?
3. Are the Nordson® replacement parts built to similar or exact Nordson® specifications and do they offer the same warranties?

The highest quality replacement parts that operate with Nordson® systems typically offer a 25% to 30% savings over comparable Nordson® equipment. Be wary of  components priced at even greater savings, as this is typically an indication of lower quality.
