    price: contact company for price

    Soft PVC extruder screw cylinders

    Specification

    Screw diameter: Ø15-300MM L/D:15-45

    Barrel diameter: Ø25-500MM Length:300-1000MM

    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.
