Forming and Sizing section FFX Forming Technology

FFX (Flexible Forming Express) is an advanced forming system that uses universal rolls in the open section and adjusts roller positions (up/down, left/right) to accommodate various pipe sizes and wall thicknesses. Key advantages:

🔄 素早い切り替え: Only sizing rolls need to be replaced, switching in 10–20 minutes
💰 Tooling Cost Saving: 80%+ roll sets are reusable across sizes
🎯 High Dimensional Accuracy: Enhances weld seam alignment and consistent outer diameter
⚙️ Smart Integration: Compatible with auto roll change carts and parameter memory systems

Quick Roll Change System Advantages:

The system allows fast replacement of full roll stands:
Rails or hydraulic carts slide out entire roll units
Single-button locking and positioning
Less than 20 minutes per changeover
Supports mold ID management and digital recipe storage
