Circulation Position

The two reactive materials used to create foam,

“A” and “B,” are kept separate until they reach the

GX16 mixhead. If the gun is not dispensing, the

materials simply circulate back to the day tanks.

Dispense Position

During the dispense mode, the metering pumps

precisely deliver both materials to the mixing head

at the required ratio, ﬂow rate and temperature.

The chemicals combine in the mix chamber by

impingement mixing. The mixture is then injected

into a mold or cavity.
