The Radius 5 gallon RTM dispenser is designed to
pump resin from a 5 gallon straight-sided pail.
The pail is placed on the base plate of the injector
and a platen is lowered into it. The bottom of the
platen is heated and kept in contact with the resin
by pneumatic actuators. Prior to an injection the
user must specify two pressure set points. During
an injection once the pressure builds to the first
set point the flow rate will be reduced to a lower
setting. The second pressure set point is the desired
hydrostatic pressure. Displacement of resin is accomplished
by a gear pump located in the center of the platen
that is controlled by an electric motor.
