Metal Slitting Line Cutting Tools & Integrated Tooling Solutions

At the heart of every high-performance slitting line is a precision-engineered tooling set. We provide more than just blades; we offer complete slitting solutions designed to minimize downtime, eliminate burrs, and extend tool life. With micron-level tolerances (± 0.001mm,can also reach:±0.0005mm) and over 20 years of manufacturing expertise, our tools are the choice for industry leaders in aluminum, steel, and specialized alloy processing.

Optimized Tooling Configurations for Diverse Materials

Different metals require different blade geometries and material grades. We customize your tooling setup based on your specific production needs:

Material Type

Focus

Recommended Tooling Strategy

Stainless Steel

Surface Protection

Tungsten Carbide Slitters paired with High-Elasticity Polyurethane Stripper Rings to prevent scratching.

Silicon Steel

Burr Control

Ultra-Fine Grain Carbide Knives with specialized clearance settings to ensure magnetic properties remain intact.

Thin Foil (0.05mm)

Micron Accuracy

Zero-Tolerance Spacers and lapped blades for high-speed, high-precision foil slitting.

Aluminum & Copper

Anti-Galling

Polished Mirror-Finish Blades with specialized coatings to prevent material build-up on the edges.

The Complete Slitting Line Layout (System Components)

Our integrated approach ensures that every component in the slitting stack works in perfect harmony:

Precision Slitter Knives

The core cutting component, available in D2, H13, and Carbide.

Rubber Stripper Rings

Bonded or loose-type rings that ensure stable feeding and scratch-free discharge.

Hardened Steel Spacers

Precision-ground spacers that dictate the exact width of your slit strips.

Lightweight Shims

For micro-adjustments to achieve the perfect horizontal clearance.

Overarm Separator Discs

To guide and separate the strips during the recoiling process.

Pro-Tips for Maximizing Slitting Efficiency

Optimized Horizontal Clearance

Achieving the correct "gap" between blades is the secret to burr-free edges. We provide custom clearance charts based on your material thickness and tensile strength.

Correct Shore Hardness

Selecting the right hardness for your rubber stripper rings (e.g., 70-90 Shore A) prevents "strip waviness" and ensures proper tension.

Regular Regrinding Programs

A proactive maintenance schedule prevents micro-cracks from developing into major blade failures, extending total tool life by up to 40%.

Zero-Error Stacking

Using our micron-accurate spacers eliminates cumulative errors across the arbor, ensuring the last strip is as precise as the first.

Technical Excellence & Quality Control

Micron-Level Tolerance Control

We maintain thickness tolerances as tight as ± 0.001mm(can also reach:±0.0005mm) and parallelism within 0.002mm to ensure the absolute accuracy of your slitting stack.

Strict Heat Treatment Processes

In-house vacuum heat treatment ensures uniform hardness and optimal microstructure, preventing blade chipping and premature wear.

Premium Material Sourcing

We use high-purity tool steels (D2, H13) ,high speed steel,and ultra-fine grain Tungsten Carbide, selected for their superior edge retention and impact resistance.
