🔧 What is “Conical Twin Screw 92/188”?

The “92/188” refers to a conical twin screw and barrel specification commonly used in PVC extrusion machinery. It means:

• 92 mm:Small head diameter at discharge end .

• 188 mm:Feed end big end diameter

This specification is widely used in high-output PVC extrusion lines.

🧩 Technical Overview:

📌 Application Fields:

• PVC pipe extrusion (e.g., drainage pipes, conduit)

• PVC profile extrusion (e.g., window & door profiles)

• PVC/WPC foamed boards and flooring

• Cable trunking and decorative profiles

⚙️ Key Advantages:

1. Excellent plasticizing: The conical shape increases compression and shearing, ideal for heat-sensitive materials like PVC.

2. High output: 92/188 is designed for large-volume production.

3. Durability: Optional bimetallic or alloy materials for high wear and corrosion resistance.

4. Stable operation: Well-engineered for continuous high-load performance.

🏭 Typical Users:

• PVC pipe manufacturers

• PVC/WPC profile factories

• Foamed board or flooring producers

• Large-scale extrusion line suppliers
