Conical Twin-screw Profile Extrusion Line

Introduction of Conical Twin-screw Profile Extrusion Line

The Conical Twin-Screw Profile Extrusion Line is a highly efficient and robust system designed for the large-scale production of plastic profiles using PVC powder as the primary raw material. This type of extrusion line is equipped with a conical twin-screw extruder, which is specifically designed to handle high filler content (such as calcium carbonate (CaCO3) and ensure long-lasting performance. It is widely used for manufacturing cable trunks, roof gutters, window frames, ceiling boards, wall panels, door panels, and door boards. Below is a detailed introduction to the machine, its features, and its models:

Key features of the cable trunking extrusion machine

1. Conical Twin-Screw Extruder:

• The conical twin-screw design ensures excellent material mixing, melting, and homogenization.

• Ideal for processing PVC powder with high filler content (e.g., calcium carbonate).

• The gradual compression of the conical screws improves material flow and reduces wear.

2. Special Bi-Metal jacket Design On Screw and Barrel:

• The screw and barrel are made from special bi-metal materials, ensuring high wear resistance and a longer lifespan.

• Suitable for processing abrasive materials like PVC with high CaCO3 content.

3. High Output Production:

• Designed for large-scale production of profiles, making it ideal for industrial applications.

• Capable of producing both single large profiles and multi-cavity designs.

4. Versatility:

• Can produce a wide range of profiles, including complex shapes and designs.

• Suitable for rigid, semi-rigid, and flexible profiles.

5. Energy Efficiency:

• Advanced heating and cooling systems optimize energy consumption while maintaining high output.

Ceiling board extrusion line components and process

1. Conical Twin-Screw Extruder:

• The PVC powder (with fillers like CaCO3) is fed into the extruder, where it is melted and homogenized.

• The conical screws gradually compress and melt the material, ensuring uniform consistency.

2. Die Head:

• The molten PVC is forced through a die head, which shapes it into the desired profile.

• The die head can be designed for single or multi-cavity production.

3. Cooling System:

• The extruded profile passes through a cooling system (usually water or air cooling) to solidify the material.

• Cooling ensures the profile retains its shape and dimensions.

4. Haul-Off Unit:

• A haul-off machine pulls the cooled profile at a controlled speed to maintain consistency in the extrusion process.

5. Cutting Unit:

• The profile is cut into the desired lengths using a cutting machine.

• For continuous profiles, the cutting unit can be synchronized with the extrusion speed.

6. Stacking or Winding Unit:

• The finished profiles are stacked or wound for packaging and distribution.

• 
  

Applications of PVC door panel extrusion line

1. Cable Trunks:

• Produces durable and flame-retardant cable management systems.

2. Roof Gutters:

• Manufactures weather-resistant and UV-stable gutters for roofing systems.

3. Window Frames:

• Creates strong, lightweight, and thermally efficient window frames.

4. Ceiling Boards:

• Produces decorative and functional ceiling panels for interior design.

5. Wall Panels:

• Manufactures durable and aesthetically pleasing wall cladding.

6. Door Panels and Boards:

• Creates lightweight yet sturdy panels for doors and partitions.
