Astro Packaging KB20 Hot Melt Glue Machine


Astro Packaging KB20 Hot Melt Glue Machine

High Performance Extrusion Melt Unit - The versatile KB20 Melt Unit supplies hot melt adhesive for a wide range of manual and automatic packaging and product assembly operations. The KB20 glue machine holds up to 20 pounds (9Kilograms) of hot melt in pillow, pellet, slab or bulk form.

The unique tank shape concentrates heat at the bottom while maintaining cooler temperatures at the top. This minimizes adhesive degradation and charring which reduces pump, hose and nozzle plugging. A powerful electric motor with a positive displacement gear pump pressurizes and feeds adhesive through heated hoses to handguns or automatic applicators.
