Fiber Chopping
What is Chopping or Precision Cutting?
Precision cutting, commonly referred to as "chopping", is the process of converting continuous filament fibers into uniform, discrete lengths. These chopped fibers are typically cut to customer-specified sizes ranging from a few millimeters to several inches, depending on the end-use application. This process is essential for applications requiring improved dispersion, controlled fiber loading, or compatibility with specific processing equipment like molders, compounders, or paper manufacturers.
The Process of Precision Cutting
At Rocket-Fibers, we utilize specialized machinery that feeds continuous tow or multifilament yarns through tension-controlled rollers into high-speed rotary blades or guillotine-style cutters. The fibers are cleanly severed at precise lengths, with minimal fraying or thermal damage.
We offer:
- Custom cut lengths from 0.25 mm to over 100 mm
- Clean, consistent cuts for uniform distribution
- Material flexibility: para-aramid (Kevlar®), UHMWPE, Vectran®, Technora®, carbon fiber, polyester, and more
- Optional surface treatments, finishes, or packaging to fit your application
Whether you need loose fill, densified sliver, or pelletized formats, our precision-cut fibers are prepared to meet strict tolerances and performance requirements.
Benefits of Precision Cut Fibers
- Improved dispersion in resins, coatings, concretes, or papers
- Enhanced mechanical properties such as strength, stiffness, or thermal resistance
- Custom integration into composite systems or molding compounds
- Efficient material handling for automated systems or batching
- Reduced processing issues, such as fiber clumping or poor distribution
