Hot Melt Equipment Features

Here are a few of the various equipment features that are available with our hot melt systems.


Our platen has 6,000 square inches of melting surface area, which is TWICE the area of our nearest competitor. More surface area means better heat transfer, faster drum changes, less downtime for heating up, and higher production rates with a single machine.

Cast-In Heaters

The heaters are molded into our competitors’ platens. When their heaters fail, the platen must be replaced. Our 4230 platen is heated with two removable heaters that can be easily changed out by the customer. It is a lot cheaper to replace a heater than a platen, and our heaters can be replaced in about 20 minutes.


Our heated platens use our patented Seg-O-Seal® system. Our seals last far longer than the competitions’ seals, and maintenance is a snap. In fact, a damaged section can be repaired in minutes without replacing the entire seal, even while the platen is hot.

Gear Pumps

Our competitors often use piston pumps. They are more complicated and difficult to maintain than our gear pump. Piston pumps have more wear parts, need periodic rebuilding, need a constant supply of oil to maintain their seal, and the output pressure fluctuates as the piston goes up and down. Our hardened gear pump requires no oil, does not wear, and supplies a smooth, constant flow of adhesive to your process. Since the pump is mounted on top of the follower plate, it can be replaced in about 20 minutes.


Our competitors use proprietary controls. We use an off-the-shelf PLC that can be ordered online and customized at a fraction of the cost.


The hoses have quick disconnect couplings, so a hose can be changed in about 5 minutes. Also, our hoses come standard with (2) RTD’s so if one fails, you can switch to the 2nd RTD and not have to replace the hose.

Less Material Waste

Another advantage of our unique platen is that it leaves less material in the bottom of a drum. A lot less! Competing machines typically leave 25 – 40 pounds of material in a drum. We normally leave about 2 pounds of material or less. We have had customers get a 3-month payback on their Uniflow from material savings alone.

Faster Pump Speed

We guarantee a 40% higher pump speed than any other drum unloader, but we often do even better than that. Many customers have been excited to find that their new Uniflow pumps twice as fast as other drum unloaders. How do we do it? We melt faster with our high-performance platen.

Rated By Mark C.

“Before purchasing Uniflow equipment, we started out using cold press, an incredibly labor-intensive process. As demand increased, we moved over to using a roll coater with a 5-gallon pail unloader. Over time, demand continued to increase, and it occurred to us that the labor involved in changing a 5-gallon pail was not much different than changing a 55-gallon drum, so we purchased a Uniflow hot melt drum unloader. I was, at first, reluctant to make the capital investment in a larger hot melt unloader, but the Uniflow system has met or exceeded my expectations in every way possible. There has been a significant improvement in productivity from using a 55-gallon drum unloader. The operator interface is simple and clear. The Uniflow team did a fantastic job of training our employees. We were very pleased with the install. The technician, the sales team, and everyone at Uniflow has been very helpful and patient.”
