The machine can be set with a timer to retract (suck back) the screw slightly at this point (for 1 or 2 s before injection and for about 2.5 cm) so as to reduce drool out of the nozzle. This melt decompression feature may avoid need for a nozzle shutoff valve and is essential to relieve pressure in hot runner molds, which are discussed later.
