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
Description
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
Widths.
Screw tips to fix the screw set axially
Gear teeth connection to ensure power flow between the screw shaft and screw
Elements.
FEATURES
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.

Prospects:
Surely you will also get professional machines and characteristic services here. Let's create more together!
Characteristics of our machine:
Euro-style rectangle barrel, reflux refrigeration channel is optimized and disposed, which makes temperature difference in D areas smaller.
Innovated design of heater tightened style insures high efficiency of heat transfer and high longevity of heater.
According to the material and special technics demands, the material of cyliner can use high quality nitrided steel, corrosion proof or antifriction with corresponding process.
Various modes of pelletizing, such as water-cooling strand, air-cooling pelletizing, water-ring pelletizing, under water pelletizing, etc.
The screw elements and kneading blocks are designed, by precise processed, agile combination, with interchangeability, which can fulfill efficient self-cleaning, transmission, compounding, pressure-forming, etc. The screw is made of high tool steel 38 CrMoAlA or W6Mo5Cr4V2 by special heat-treatment, which is possessed with high corrosion-resistand and high functions.
The machines are designed by using the "toy bricks" principle, the screw configuration, barrel setup, L/D or mode of feeding and venting, screen changing, way of granulating, and the control mode can be optimally adjusted according to different material properties and requirements in consideration of the versatility in each general applications.
Metering feeders are equipped with single screw, twin screw, hollow screw, forced-feeding, side-feeding system, etc. To meet different requirements of feeding, such as powder, pellet, pump and liquid material.
New-style gear transmission system:
New-style project of parallel three-axises driving makes the convey axis, convey chain, decelerate and torque get together, which keep it compact, and the key bearings are imported.
The computer designs to potimize gear parameters and strenghthen safe overmeasure.
The selected material of drive components is dainty. Including super intention alloy cementiteing steel, cementiting and grinding technics, strengthening of tooth face. So they can ensure high torque, high precision and low noise.
Soakage and spraying lubriation integrate smoothly.
