Pumping any type of PUR (polyurethane reactive) adhesive requires a hot melt drum unloader, as the material is solid at room temperature and must be heated to convert it to liquid form. KLEIBERIT HotCoating® materials deliver unique performance advantages, but also create challenges for the drum unloader. This document provides information on HotCoating® and on […]
Hot melt drum unloaders are used to heat high-viscosity polymers and pump them into a customer’s manufacturing process.
Some of the hot melt materials that are typically processed include:
Pressure Sensitive Adhesives (PSA)
Polyurethane Reactive Adhesives (PUR)
Among many others
Manufacturing processes that use hot melt drum unloaders include roll coating, cable manufacturing, spray coating, and hand […]
This case study demonstrates the significant advantages of the Model 230 Uniflow, specifically at Functional Coatings, a custom, private label contract manufacturing company.
Hot Melt Drum Unloader Equipment Manufacturing
Manufacturers have historically chosen Uniflow drum unloaders when facing unique challenges. We have pumped materials at rates up to 2,000 pounds/hour and with viscosities as high as […]
Worthen had recently installed two new hot melt drum unloaders built by a competitor, each of which was expected to pump 600 lbs of pressure-sensitive adhesive (PSA) per hour, but only ended up pumping 325-350 lbs per hour. That’s when UNIflow stepped in.
