Product Details
Bimetallic Screw Barrel For LDPE / HDPE / PP / PE / PVC Blowing
Molding Machine
1 . Description
We are the manufacturer of supplier of screw and barrel in
china,including designing,manufacturing and sales for these
products,we can make any specification of extruder screw barrel and
injection molding screw barrel for
Engle,Nigrobossi,KMD,NPM,BOY,Haitian,Demag,HUSKY, Nippon Steel,
Toshiba, Nissei,Mitsubishi and etc. We also can supply all types of
screw and barrel according to your different requirements.
Screw diameter:Φ15mm-Φ360mmL/D=15-56
Length of screw and barrel/cylinder:8000mm
According to different material and plastic products to design
different screw structure ,compress rate and L/D.
According to different material and plastic products to design
different Barrel with exhaust system and IKV force load system.
The cross-sectional area is changed by adjusting the flight lead
and thread depth, effectively eliminating sudden cross-sectional
deformation and impeding resin pooling and extrusion fluctuations.
Our (Barrier Mixer) with its high rolling and chaos effects can be
mounted on the barrier outlet and screw tip to further enhance
kneading and output rate.

3 . Comparsion of the output (LDPE)
Pressure is generated if resin passes over the barrier, forcing any
air in the melted resin back to the feed side and effectively
preventing the intrusion of air bubbles on the sub flight side.
This is highly effective with resins that generate bubbles such as
PS, PA, PET and EVOH.
