Product Description

YAOAN CA Co-Rotating Parallel Twin-Screw Extruder Pelletizing Machine

1. Cellulose Acetate (CA) Compounding

• Material: Cellulose Acetate (CA) is a biodegradable thermoplastic derived from natural cellulose. It is widely used in medical applications (e.g., surgical tools, drug delivery systems), eyewear (spectacle frames), combs, and other consumer products.

• Process: The twin-screw extruder processes CA with additives (e.g., plasticizers like oil) to produce high-quality CA pellets.

• Advantages over Single-Screw Extruders:

  • Better mixing and homogenization of CA and additives.

  • Improved pellet quality due to precise temperature and shear control.

  • Enhanced mechanical and aesthetic properties of the final product.

 

2. Color Masterbatch Production

• The machine is capable of producing color masterbatches for a wide range of polymers, including:

  • PP (Polypropylene)

  • PE (Polyethylene)

  • PS (Polystyrene)

  • PC (Polycarbonate)

  • PET (Polyethylene Terephthalate)

  • PMMA (Polymethyl Methacrylate)

  • PETG (Polyethylene Terephthalate Glycol)

• The co-rotating twin-screw design ensures excellent dispersion of pigments and additives, resulting in consistent and vibrant colors.

 

3. Nylon + Fiber Glass Compounding

• The machine is also suitable for compounding nylon (polyamide) with fiberglass to produce reinforced engineering plastics.

• Applications include automotive parts, industrial components, and consumer goods that require high strength, stiffness, and thermal resistance.

 

4. Versatility

• The co-rotating parallel twin-screw extruder is a highly versatile machine capable of processing a wide range of materials, including:

  • Thermoplastics (e.g., CA, PP, PE, PS, PC, PET, PMMA, PETG, nylon).

  • Additives (e.g., plasticizers, stabilizers, flame retardants).

  • Reinforcements (e.g., fiberglass, carbon fiber).

  • Recycled materials.

 

Advantages of Co-Rotating Parallel Twin-Screw Extruders

1. Superior Mixing and Homogenization:

   • The co-rotating screws create intense shear and elongational forces, ensuring thorough mixing of materials and additives.

2. Precision Control:

   • Advanced control systems allow for precise adjustment of temperature, screw speed, and feed rate, ensuring consistent product quality.

3. Flexibility:

   • Modular screw and barrel designs enable customization for different materials and processes.

4. High Efficiency:

   • Continuous processing reduces production time and energy consumption compared to batch processes.

5. Better Pellet Quality:

   • Compared to single-screw extruders, twin-screw extruders produce pellets with more uniform size, shape, and material properties.

6. Machine model:

   AFJ-72	72mm	36-48:1	400.500.600	160KW	100-350
   AFJ-82	82mm	36--48:1	400-600	110-180KW	200-500
   AFJ-92	92mm	36-48:1	300 or 600	180-220KW	300-900

 

Applications of the Final Pellets

• CA Pellets: Used for manufacturing medical devices,spectacles frames, combs, and other consumer products.

• Color Masterbatches: Used in injection molding, blow molding, and extrusion processes to add color to plastic products.

• Nylon + Fiberglass Pellets: Used in high-performance applications requiring strength and durability, such as automotive and industrial components.

 

Comparison with Single-Screw Extruders

• Single-Screw Extruders:

  • Limited mixing capability, making them less suitable for complex formulations.

  • Lower shear forces, resulting in less uniform dispersion of additives.

  • Generally used for simpler tasks like melting and extruding single polymers.

• Twin-Screw Extruders:

  • Superior mixing and compounding capabilities.

  • Ideal for complex formulations, such as CA + additives or nylon + fiberglass.

  • Produces higher-quality pellets with better mechanical and aesthetic properties.

 

Conclusion

The co-rotating parallel twin-screw extruder pelletizing machine is a highly versatile and efficient solution for compounding and pelletizing a wide range of materials, including Cellulose Acetate (CA), color masterbatches, and reinforced polymers like nylon + fiberglass. Its ability to produce high-quality pellets with superior properties makes it a preferred choice over single-screw extruders for advanced applications in the plastics and polymer industries. Whether for medical, automotive, or consumer products, this machine offers unmatched flexibility and performance.
