Core Features & Advantages
The L/D ratio of the unit, combination form of barrel and twin
screws, feeding method, screen changing & pelletizing method, and
electrical automation control mode can be customized for different
plastic compounding processes, realizing the optimal matching of
equipment and production requirements.
Configurable with 1, 2 or multiple vacuum vents to maximize the
removal of waste gas and volatile substances in the plastic
compounding process, effectively improving the purity and physical
properties of finished plastic products.
Various efficient screen changing methods are available, including
manual, automatic, hinged, single-station and multi-station types,
to meet the filtration needs of different plastic raw materials and
compounding formulas, adapting to continuous production of plastic
compounding.
Optional pelletizing solutions for different plastic compounding
product requirements, easy to switch and suitable for mass
production:
- Water-cooled strand pelletizing
- Air-cooled die-face hot cutting
- Water-ring die-face pelletizing
- Eccentric water mist pelletizing
- Underwater die-face pelletizing
Flexible barrel opening designs (top, bottom, side) for easy
maintenance and raw material cleaning, suitable for switching
different plastic compounding formulas. Circulating cooling water
channels ensure accurate and stable temperature control during
processing, and bimetallic wear-resistant lining has high wear
resistance and precision, meeting the long-term production
requirements of plastic compounding.
Support multiple feeding forms to adapt to different raw material
states in plastic compounding (powder, granule, bulk material,
liquid additive):
- Single screw / twin screw / hollow screw feeding
- Forced feeding / side feeding
- Liquid injection system
The power part can be configured with AC frequency conversion
control or DC speed regulation control to realize stepless speed
adjustment, matching the optimal process speed for compounding of
different general plastics and ensuring the uniformity of plastic
mixing.
New tri-axle parallel transmission box structure with oil-immersed
and forced cooling lubrication, equipped with low liquid level
alarm function, enabling high-speed, high-torque and stable running
of the unit, and ensuring continuous and efficient production of
plastic compounding.
