Detail Description
Engineered for high-speed electrode winding lines, these tungsten carbide industrial knives deliver ultra-precise shearing for lithium battery cell manufacturing. Each electrode guillotine knife is crafted from ultrafine grain cemented carbide, with optimized edge geometry to reduce foil chipping and powder loss.
These knives pass 300x edge magnification tests with notch depths <2μm, ensuring clean shearing and maximum consistency during continuous operation. The Ta-C (Tetrahedral Amorphous Carbon) coating significantly boosts wear resistance and lifespan—especially under high-frequency cutting in automated lines. Trusted by industry-leading battery makers, these knives have become essential replacement tools in electrode cross-cutting machines worldwide.

Frequently Asked Questions
Q1: Can I order custom sizes for different machines?
Yes, we offer OEM and custom configurations to fit your specific winding and cross-cutting equipment requirements.
Q2: What materials are supported by these knives?
These industrial knives are fully compatible with NMC, LFP, LCO, and other mainstream Lithium-ion electrode materials.
Q3: How do these knives reduce burrs and dust during production?
Our precision edge grinding and dense carbide composition prevent edge powdering, minimizing defects in the foil layers and suppressing dust.
Q4: Is the Ta-C coating necessary for my application?
While optional, Ta-C provides a harder, low-friction surface which is ideal for significantly improving tool life in high-speed or automated production lines.
Q5: What is the typical lead time and minimum order quantity?
The standard minimum order quantity (MOQ) is 10 pieces, with a production lead time of approximately 30–35 working days.
Q6: Are the products quality certified?
Yes, all industrial knives are ISO 9001 approved and undergo rigorous 300x magnification inspection to ensure notch depths remain below 2μm.
