Frequently Asked Questions

What makes these slitting blades more durable?
Our proprietary tungsten carbide formulation and advanced grinding technology ensure long-lasting sharpness and resistance to micro-chipping, even under continuous high-speed operation, lasting 3-5 times longer than standard blades.
Can you produce custom blade geometries?
Absolutely. We specialize in custom metal foil slitting blades with modified edge profiles, special coatings, or non-standard dimensions to match your specific machine requirements.
What is the precision tolerance of the blades?
We maintain ultra-high precision with thickness tolerances of ±0.001mm, outer diameter tolerances of ±0.0025mm, and parallelism of 0.001mm.
What kind of surface finish can I expect?
Our blades undergo advanced mirror polishing to achieve a surface finish of Ra 0.01μm, ensuring clean, burr-free cuts on delicate foils.
What maintenance is required for tungsten carbide blades?
Interchangeable tungsten carbide slitting blades need only periodic cleaning with specialized solutions. Proper storage in dry conditions maximizes lifespan and prevents edge degradation.
