Machine Advantage (Waste plastic recycling granulator machine):

1. Power saving. Can save 30% power for a similar product in the market.

It means saving 30% on electric charges for factory owners.

2. More productive. Because our screw diameter is smaller.

3. Machine with converters, protect the whole machine. When there is a low electrical current start-up machine, it protects the gearbox and protects the screw.

4. Using more wearable material for the barrel and screw. Longer life for barrels and screws


Product Characteristic (waste plastic recycling granulator machine ):

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

2. Screws can be designed and offered with a wide range of heat treatments at no extra cost.

3. Gearbox with forced cooling filtration system, reach Europe standard.

4. Screw and barrel use special steel with heat treatment. Processing reaches the international standard.

5. Charging basket with P.L.D automatic temperature control, the material never changes color to yellow ( especially for clear material), will not make blackspot.

6. With automatic or vacuum degassing systems (Option)

7. Can choose a Manual screen changer or Hydraulic screen changer.

Different mode of screen changer:

Manual type screen changer: more steady for the plastic quality, but need man-made working. 

Hydraulic type screen changer: replacement screen is easier, more simple.

Dual Bolt double screen cavities hydraulic screen changer: higher production efficiency.


Plastic dyeing or multi-purpose mixing and granulation with fire retardants, fibers, masterbatches, etc.

Engineering plastics, high-temperature plastics, high-performance plastics, environmental protection plastics, and other special pelletizing.

Recycling and pelletizing of all types of plastic scrap.
