Water Ring & Underwater
Pelletizing Blades
OEM-compatible TiC pelletizing blades and knife holders engineered for stable cutting, extended service life, and reliable performance in continuous pelletizing lines.
Stable Cutting Performance for Continuous Pelletizing Operations
In water ring and underwater pelletizing systems, unstable blade contact, improper hardness selection, or insufficient holder rigidity can quickly lead to inconsistent pellet quality, die face wear, and frequent downtime.
Inconsistent Pellet Size
Uneven cutting contact can cause irregular pellet geometry and surface defects.
Die Face Wear
Improper blade matching may accelerate die face wear and increase maintenance cost.
Frequent Blade Replacement
Premature wear, edge rolling or chipping increases downtime.
Vibration & Chatter Marks
Insufficient holder rigidity can lead to unstable cutting and poor pellet consistency.
With 10+ years of specialized localization experience, our blade and holder systems are engineered to maintain stable cutting contact, reduce vibration, and extend service life in continuous production.
Precision Blades
Stable cutting with high wear resistance for continuous pelletizing.
Rigid Holders
High-rigidity holder design helps reduce vibration and maintain stable cutting contact.
Consistent Pellets
Stable cutting supports uniform pellet size and improved surface consistency.
Why Our Blades Perform Differently
Material selection, hardness matching and precision manufacturing determine whether a pelletizing blade can maintain stable performance over long production cycles.
German-Imported TiC Material
High-grade titanium carbide imported from Germany provides excellent wear and corrosion resistance for continuous water ring and underwater pelletizing applications.
Extended Service Life
Proven applications have achieved service life of up to approximately 12 months, helping reduce replacement frequency, downtime and total operating cost.
OEM-Compatible Replacement
BKG® and MAAG® compatible blade and holder configurations can be engineered to match existing installation requirements, minimizing changes to your pelletizing equipment.
Hardness & Geometry Matching
Hardness, blade angle and cutting geometry are selected according to material, throughput and operating conditions to reduce wear, chipping and unstable cutting.
More Stable Cutting
Optimized blade matching supports stable blade-to-die contact.
More Consistent Pellets
Stable cutting improves pellet geometry and surface consistency.
Longer Service Life
High wear resistance helps reduce replacement frequency.
Lower Operating Cost
Fewer replacements and stoppages help reduce overall maintenance cost.
* Service life varies depending on processed material, throughput, pelletizer model and operating conditions.

Piece-by-Piece Inspection
Every blade is inspected before packing and shipment — not by random sampling.
Visual Inspection
Each blade is checked for surface defects, damage and overall workmanship.
Cutting Edge Inspection
The cutting edge is inspected to ensure edge integrity, sharpness and consistent cutting quality.
Blade Angle Verification
Critical blade angles are checked to ensure correct geometry and stable contact during pelletizing.

Operating Cost
The Challenge
- Original HSS blades experienced edge rolling, chipping and corrosion.
- Typical blade life was only 1–2 months, increasing replacement frequency and downtime.
Our Solution
- Upgraded the blade material from HSS to German-imported TiC.
- Optimized the original angled blade into a straight-blade configuration for more stable cutting.
- Updated the holder configuration to improve blade support and operating stability.
The Result
- Blade life increased to approximately 12 months.
- Overall operating costs were reduced by approximately 30–40%.
- Pellet consistency improved with fewer tails and reduced dust.
This case is based on an actual customer application using a MAAG® underwater pelletizing system for PET. Actual service life and cost savings may vary depending on material, throughput, operating conditions and maintenance.
