Material

38CrMoAlA(JIS SACM645)

42CrMo(AISI 4140)

9Cr18MoV, stainless steel, etc

Screw Design:

The screw should be single flighted, constant pitch, with the

pitch equal to the diameter and the

length equal to 24 diameters. It should be bored for

cooling.Screw Flights should be flamehardened.

The screw should be AISI4140 chrome plated.Since flexible

PVC compounds can cover a wide range of

hardnesses, the screw design and dimensions are less critial

than for rigid pvc.

Mixing pins and other types of mixing sections are often

incorporated in a screw design to enhance

dispersion, espeically when adding concentrates to a

naturalbased compound.Screws with mixing

pins typically have 12-14 flights in the metering section.

Barrier screws are still another type of design that can be

used for extruding flexible PVC.
