In addition to crafting high-quality drum unloaders for cable stranders, IMMCO provides equipment for pumping the mastic.

Uniflow machines pump any type of hot melt material. For instance:

Strand Filling Mastic

Chase BlH20ck® is an ideal filling compound for cable stranders, but it’s highly viscous, and using it isn’t simple. However, a Uniflow machine can pump this material at a decent rate.

A Uniflow drum unloader also pumps to the bottom of the barrel. Competing machines leave behind 25-40 pounds of material waste in each drum, whereas a Uniflow leaves just 2 pounds or less.

PUR (Polyurethane Reactive) Adhesives

PUR cures when exposed to air, and IMMCO’s patented Seg-O-Seal system completely locks out air. After pumping half a drum of PUR and letting the machine sit for six months, it started again and none of the PUR in the drum had cured.

PSA (Pressure Sensitive Adhesives)

There are plenty of competitor machines that handle PSAs, but IMMCO’s pumping rates are superior no matter the PSA. A Uniflow can pump every hot melt material at least 40% faster, guaranteed.

Abrasive Pumping

Some manufacturers use abrasive adhesives for product durability, but the downside is the wear and tear on their equipment—ordinary pumps deteriorate quickly. IMMCO has a gear pump that lasts over twice as long as competing machines.
