3 Holes Zirconia Ceramic Blade

Zirconia ceramic blades are high performance cutting tools that combine advanced material technology with precise manufacturing processes. Their core features can be summarized as “high hardness, strong corrosion resistance, and high cleanliness”, but they also have a drawback of “brittleness”. The specific characteristics are as

follows:

1. Extremely high hardness, maintaining sharpness for a long time
2. Chemically inert, never rusting
3. High cleanliness, safe and non-toxic
4. Dense material, easy to clean
5. Inherent brittleness, poor impact resistance

Applications:

1. Plastic film manufacturing (PE/PET/BOPP/PA, etc.)
2. Slitting of lithium battery separators and electrode materials
3. Optical display films (polarizing films, diffusing films)
4. Food and pharmaceutical packaging composite films
5. Metal foils (copper foil, aluminum foil) and self adhesive materials

Why Choose Zro2 Ceramic Blades?

Compared with traditional steel or hard alloy blades, zirconia ceramic blades have three major advantages when slitting films:

1. 1. No metal contamination: No metal particles fall off, suitable for clean workshops and electronicgrade film production;
2. 2. Longlasting sharpness: The high wear resistance of ceramics makes the blade life 3-5 times that of some metal blades;
3. 3. Chemical corrosion resistance: It is less likely to rust or become dull when dealing with films containing coating liquids or organic solvents.

 

If your slitting production line is confronted with frequent blade replacement, excessive dust and burrs, or metal contamination, 3 hole zirconia ceramic blades offer an effective upgrade solution.
