For the 1st five tests, [DELTA] linearly increases with log(P), suggesting a gradual engagement of the
screw into the gearbox sleeve at increasing die backpressure.
Now drive the
screw into the angled pilot hole to complete the job.
From the bottom of the carriage, insert the
screw into the tapped hole to the rear of the pintle.
The compound is then forced from the
screw into the barrel in the Transfermix section, where the opposite flighting of the screw and barrel create intensive shearing and hence heating and homogenization of the compound.
After you insert the step or "T"
screw into the proper slot, you simply grip the Buck Screw and apply pressure against the tree, rotating clockwise until the step or "T" screw is in the tree.
The receding flights of the screw intersect with the increasing channels of the barrel, so that the extrudate is partly forced out of the
screw into the barrel and hence sheared normal to the flow already transferred into the barrel.
