Lighter, Stronger & Cleaner

Developed exclusively by BOBST for flexo printing folder-gluers/flexo printing rotary die-cutters machine, the Carbon Fiber Doctor Blade Chamber (CFC) redefines what’s possible in printing chamber technology.

With a patented carbon fiber body that’s 50% lighter than aluminum, this chamber is the lightest solution on the market—without compromising strength or performance.

The carbon fiber construction delivers long-lasting anticorrosive protection, creating a resistant barrier against humidity and aggressive production environments. Combined with BOBST’s integrated washing spray system and reinforced quick-blade clamping design, the CFC transforms maintenance routines and accelerates job changeovers.

The CFC Advantage

Effortless Handling

At 50% lighter than aluminum chambers, operators can handle, install, and maintain the CFC with significantly less physical strain and faster turnaround.

Built to Last

24% more rigid than competitor carbon chambers, preventing bending while resisting corrosion and aggressive production conditions for extended lifespan.

Faster Changeovers

Integrated washing sprays keep the chamber clean and minimize residual ink, reducing job changeover time and boosting productivity.

Consistent Color Quality

Carbon surface and efficient washing system prevent residual ink mixing, ensuring color consistency from run to run.

Long-Term Performance

Enhanced Rigidity

 

  • The high-carbon profile is 24% more rigid than standard competitor carbon chambers. 
  • Prevents bending and maintaining precise blade contact.

 

Corrosion Resistance

 

  • Carbon fiber construction forms a protective barrier against humidity and aggressive production factors. 
  • Extends chamber lifespan significantly.

 

Color Consistency

 

  • The carbon surface combined with efficient washing prevents residual ink mixing.
  • Ensures consistent color output run after run.
