Overview

FoamMelt FIT25 Melters deliver high-quality expanded adhesive on demand for a variety of bonding, sealing, and gasketing applications.

Nordson has extensive experience in expanding or “foaming” adhesives, delivering numerous benefits to our customers in various markets and applications. Foamed adhesives excel in gap filling, can enhance bonding, and even support sustainability goals through reduced adhesive and energy consumption. The FoamMelt FIT25 melter, available in standard and advanced versions, provides improved foam process control and product serviceability in a system that melts adhesive, introduces inert gas, and delivers high-quality low-to-medium viscosity foamed material.

Innovative

Both Nordson solutions utilize adhesive recirculation combined with accurate temperature, pressure, and gas injection control to deliver consistent quality foamed adhesive throughout the entire production cycle without the need to purge static material; the system is ready to work when you are. Additionally, the color touchscreen provides an intuitive user-interface that displays system status, facilitates operation, and simplifies training. Screens can be easily navigated to quickly transition between start-up and production parameters, while included fieldbus communication simplifies machine integration.

Technology

The Standard FoamMelt® FIT25 melter uses proven Nordson Automatic Density Control technology to achieve the required foam density reduction. It features a Manual Density Controller that employs a density sensor to regulate gas injection to achieve and maintain the desired foam density reduction. The Advanced FoamMelt® FIT25 melter utilizes a Smart Density Controller to enable closed-loop gas control to achieve the more precise control of foam density reduction. The Smart Density Controller uses a proprietary closed-loop control algorithm to continually adjust metering gas injection to achieve and maintain the desired foam density reduction.

Foamed Adhesive

The Nordson® FoamMelt process dramatically improves the performance of most hot melt adhesives by mixing them with inert gas, creating a homogeneous solution under pressure. As the material is dispensed, the gas expands to create a closed-cell foam. The foamed material is applied like conventional dispensing systems but provides the a lot more benefits.

Increased open time produces longer, more useful beads and provides greater flexibility.
Faster set time for increased line speeds and production rates can reduce labor and inventory cost.
Volumetric increase for greater gap filling capabilities.
Improved wetting increases the ability to bond impervious surfaces and enhances application versatility.
Lower heat density reduces heat damage and improves operator safety.
Reduced sagging or running for uniform adhesive thickness.
Reduced adhesive consumption of up to 65 percent.
Increased penetration creates stronger bonds and results in fewer rejects.
