Competitive Advantage:

1. Power saving. Single screw extruder line Can save 30% power for the similar product in the market. 

    It means save 30% electric charge for factory owner.

2. More productive. Screw diameter is more small. It means: there is more material work on our machine than the similar product in the market. 

3. Machine with converters, protect whole machine. When there is low electrical current start-up machine, it can project gear box, protect the screw.

4. HongQi single screw extruder line can work for 800#, 1000# screen mesh. 

5. Use more strong material for the charging basket and screw. So more long life for charging basket and screw.

Basic equipment of Single screw extruder line for PC gtranule:

Single screw plastic extruder machine 1piece: It is the best single screw in china market.

Feeder for granule machine 1 piece: auxiliary equipment for the extruder, make the whole Single screw extrusion line work more excellent .

Cooling tank with Moisture absorption machine 1piece

Plastic Pelletizer 1 piece

Plastic Vibrating Machine with Hopper 1 piece: Transport the transport from pelletizer to the package, and filter the oversize granule.

Product Characteristic (Single screw extruder line):

1. We creative die head heating system, guarantees the temperature achieved fast the material needed.

2. Machine with variable frequency trimming, low power switch on, instantaneous current smooth.

3. Design and offer multiple heat treatment for screw without extra fee.

4. Gear box with forced cooling filtration system, reach Europe standard.

5. Screw and charging basket use especial steel with heat treatment. Processing reach international standard.

6. Charging basket with P.L.D automatic temperature control, material never not change color to yellow ( especially for clear PC polycarbonate material), will not born blackspot.

7.With automatic or vacuum degassing systems (Option)

8. The temperature of die head , mesh changer and drum separately controlled. All drive system runs synchronously

9. Can choose Handrotating screen replacement or Hydraulic screen replacement.


1. We have more then 200 customer around our factory from 1KM ~30KM, so very welcome to our factory or our customer plastic factory for review our recycling granulator machine.

2. Our Single screw extrusion line for PC granule occupy 85% market in local market.

3. One of biggest VCR/VCD manufactures the in world is our customer.

Capability(PC) or(PC+ABS):

Model HQ-60: 80~100KG/HR

Model HQ-90: 200~300KG/HR

Model HQ-120: 350~500KG/HR

Different mode of die head  with  mesh changer :

Handrotating screen replacement: More steady for the plastic quality, but need man-made working. 

Hydraulic screen replacement: replacement screen is more easy, save labour.


For material : ABS, PC, PP, PE,HIPS, TPU, AB coloration, mix, modified, added , composite,recycling, make granular. Professional in PC granule material.
