Polyester masterbatch production extrusion machinery equipment

2.Application of compound extruder

-Mixing nature-changing: PE,PP,PS+SBS;PA+EPDM;PP+NBR;EVA+Silicon rubber,etc

-Filling nature-changing: PE,PP,EVA etc+aluminum hydroxide,magnesium hydroxide,antimony oxide.

-Colored machine pellets: PE,PP,ABS,AS,PA,EVA,PET etc+long fires,small fibres, carbon fibres, crystals and so on, etc.

3.Features of plastic extruder:

(1) Barrel

euro-style rectangle barrl, reflux refrigeration channel is optimized and disposed,which makes temperature difference in D areas smaller.

(2) Screw

the screw is made of high tool steel 38 CrMoALA or W6Mo5Cr4V2 by special heat-treatment , which is possessed with high corrosion-resistat and high functions.

(3)Metering feeders

various metering feeders --- single screw ,twin screw ,hollow screw,forced-feeding, side- feeding.

(4) New-style gear transmission system

new-style project of parallel three-axises driving makes the conve axis,convey chain,decelerate and torque get together ,which keep it compact ,and the key bearings are imported soakage 

(5)Electric control cabinet

adopting imported PLC(OMRON or SIMES) to achieve optimized process control. stronger function,steady performance and much higher accurancy 

(6) Pelletizing system for compound

---various modes of pelletizing,such as water-cooling strand,air-cooling pelletizing,water-ring pelletizing,under water pelletizing.
