Screw Speed

Hi Everyone

how should ı consider about screw speed ?

All metarials we use same screw speed ( 60 RPM )

ı think we should use different screw speed for some special plastic metarials but how?

could you please some information about this?

As long as the shot builds in time and the part passes quality, the slower the better because in theory it is more energy efficient.

certainly right @ijchan223

so how about screw speed depends on materials?

which materials needs higher or slower screw speed ?
