Small flow is harder because fixed errors do not shrink with the shot. A metering machine has a small amount of internal clearance, pump...

The decision between 2K, 3K and 4K low-pressure polyurethane metering systems is not about choosing the machine with the most tanks. It follows the...

Solvent flushing remains common in low-pressure polyurethane metering machines because the mixing head holds a small amount of reactive two-component material after every shot...

The choice among gear, piston, and screw pumps for low-pressure polyurethane metering is not a catalog decision; it is a process decision. A low-pressure...

Most low-pressure polyurethane metering problems that show up as “bad ratio” or “poor mixing” are actually viscosity problems that were not accounted for during...

Walk into almost any machine-room discussion about a new low-pressure polyurethane foaming machine and the same question comes up early: “What ratio range does...

Most output-range mistakes on low-pressure PU foaming machines do not appear at the quoting stage. They appear six months later, when a plant tries...

Most low-pressure polyurethane metering problems are blamed on the mixing head. In practice, the mixer is often only part of the story: the meter,...

Production managers rarely see the mixing head until something goes wrong: streak marks in the foam, a ratio that drifts after the first twenty...

A buyer holds two quotations: one for a low-pressure foaming machine, one for a high-pressure model. Both suppliers promise precise metering and uniform mixing....
