Product Description

Product Description
Customized Bimetallic Screw and Barrel for extrusion, recycling,  film blowing mold, pelleting machine
Screw elements are the main working parts for twin screw extruder which determined the quality and output of plastic products.With high quality,the screw elements assure plastic molecular mixing,cutting,spreading as well as reacting among themselves etc.Extremely high self cleaning performance assure the high quality of the whole production line,for this,our company combiend our experience for years,the merits about foreign countries and the customer's use,then take them into action,designed all kinds of suitable processing screw element with reasonable parameters,high self cleaning performance,wear resistance,corrosion-res 

Application

 1) Used for plastic products extrusion: blowing film, film, sheet, sheet, pipe extrusion  
 2) For chemical fiber extrusion: PET, PA6, film, non-woven fabric, rope fiber  
 3) Used for plastic recycling granulation  
 4) For cable extrusion: suitable for PVC, PE, PBT, and plastic fluoride
 

Detailed showing

 

Vented/Gas/Degassing Port Design

There have one vented port and double vented port design recycling pelletizing screw barrel, Due to material these volatile components and moisture need to be discharged during processing to ensure the final quality of the product.

Bimetallic Recycling Pelletizing Screw Barrel

As the granulator is mostly use recycled material, the material contains a lot of impurities and corrosive ingredients, so according to customer demand we will recommend to use bimetallic screw and bimetallic barrel to improve the screw barrel more longer lifetime. 

High Speed feeding barrel-separately water jacket

This separate water cooling jacket design do have excellent cooling performance and higher output capacity, with longer and deeper rectangle grooves design with internal complex cooling cycling system.

Big  Feeding Mouth 

We have big feeding mouth design to improve the feeding speed to increase the output capacity, especially for the LDPE/HDPE, PP film raw material recycling.

 

Side feeding which connect with Agglomerator 

when customer has agglomerator, it's easy for feeding and faster than the normal feeder.
also inside of the feeder have slant slot

Straight/ Spiral Grooved/Eccentricity Feeding Design
We make different feeding groove shape like straight groove, diagonal groove and eccentricity to improve feeding speed, with our high-speed screw, it will highly increase extruder output.
