Oct 23, 2014 · Those days are gone, as nearly all machine builders now lock the screw from rotating during injection. Sometimes you can see it rotate backwards for a fraction of turn, but then it stops as they have locked the screw from rotating. If you find that there is a problem with the check valve or the barrel, there is no satisfactory work-around.

If L/D ratio is more than maximum injection stroke can be up to 4.5 times the diameter of screw. The maximum swept volume of the machine with larger injection stroke should be DE- RATED to the value corresponding to 4 times diameter of the screw while comparing with other machines.

You can assume that the actual injection volume which the injection-molding machine can produce is smaller than the values indicated in the manufacturers' catalogs. The values in the catalogs are often the maximum injection stroke and just theoretical figures. The volume loss is not accounted for.

Spin Casting: Spin casting uses a rubber mold and centrifugal force instead of the steel mold (typical for injection molding) and an injection molding machine to produce parts. Typically, spin casting is done using cured rubber molds that are generated by casting …

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.
