1. Extruder replace parts
2. High quality, high accuracy
3. Screw: W6Mo5Cr4V2.38CrMoAl. SKD11. SACM645 etc

The flexible modular principle is realized with screw barrel sections from the wide
Range ofdifferent designs possible. Fast, intensive and uniform heating ofthe screw
Barrel section is ensured by electrical heaters. The barrel sections are cooled with
Water, by means ofan internal bore system, with bores arranged close to the inside
Barrel wall.

Barrel sections are available as:
Closed barrel section
Barrel section with opening for material feed or for devolatilization
The processing section is provided with stainless steel plates as a protection against
Accidental contact.
Screw Elements: High-speed steel W6Mo5Cr4V2, nitrogen treatment.
Screw Shaft: High performance alloy steels, 40CrNiMoA; With standing high load, Etc
The inter meshing screws co-rotate and wipe each other with narrow clearance so that
No residues are left in the screw flight and clean effort is thus reduce.
Screw elements with various pitches and lengths
Kneading blocks with various angles ofstagger, numbers ofkneading disks and disk
Screw tips to fix the screw set axially
Gear teeth connection to ensure power flow between the screw shaft and screw

1. Screw components designed by computer aids is kneading type, has excellent self-cleaning function, the new kneading block design effectively avoid the problems of overheating and energy consumption.
2. According to process system and formula requirements, the unit can optimize its L/D ratio, barrel structure, screw array, venting number and location, feeding method, electrical control methods etc. For rational allocation.

Packaging for exports:
Package: Wooden case or Using Anti-rust oil processing, then use stretch film cover extruder against moisture damage.
Shipping: By sea or By express
