Precision Zirconia Ceramic Scraper Blades

Precision Zirconia Ceramic Scraper Blades

TecCera supplies precision scraper blades manufactured from yttria-stabilized zirconia ceramic, typically 3Y-TZP. Through controlled forming, high-temperature sintering and precision edge grinding, zirconia scraper blades provide high wear resistance, consistent edge geometry and reduced metallic contamination in demanding wiping, metering and scraping applications.

Dimensions, mounting features, edge profiles and surface finishes can be customized according to customer drawings and operating requirements.

Key Advantages

• High wear resistance: Maintains a consistent working edge when handling abrasive inks, coatings, slurries and pastes.
• Good fracture toughness: 3Y-TZP offers greater resistance to chipping and cracking than many conventional technical ceramics.
• Corrosion resistance: Suitable for contact with many water-based inks, solvents and industrial chemicals, subject to compatibility evaluation.
• Consistent wiping and metering: Precision-ground edges support controlled removal and uniform material distribution.
• Reduced metallic contamination: The ceramic working edge avoids iron-based wear particles associated with conventional steel blades.
• Non-magnetic and electrically insulating: Suitable for applications where these material properties are required.
• Custom edge preparation: Beveled, square, rounded and other profiles can be produced according to the application.

Typical Applications

• Ink metering and doctor-blade systems
• Flexographic and gravure printing
• Battery-slurry and functional-coating processes
• Film and thin-layer coating equipment
• Paste and adhesive removal
• Electronics manufacturing
• Laboratory tape casting and material testing
• Applications involving abrasive media or reduced metallic contamination

Compatibility with anilox rolls, substrates and process chemicals should be verified through application testing. Blade pressure, alignment and edge geometry must be correctly selected to avoid excessive wear or surface damage.

Customization Options

• Blade length, width and thickness
• Square, beveled or rounded working edges
• Edge angle and edge radius
• Mounting slots, holes, notches and guide features
• Surface grinding and polishing
• Prototype and production quantities

All dimensions, tolerances and finishing requirements should be confirmed against the customer’s drawing before production.

FAQ

Q1: Why use zirconia scraper blades instead of steel blades?

Zirconia offers high wear resistance, corrosion resistance and long-lasting edge stability. It can be advantageous when processing abrasive media or when reduced metallic contamination is important. Actual service-life improvement depends on the material, speed, pressure, alignment and operating conditions.

Q2: Can zirconia blades damage anilox rolls or substrates?

Any scraper blade may cause damage if the material, edge geometry, pressure or installation is unsuitable. Zirconia blades should be evaluated with the specific roll or substrate, and the lowest effective working pressure should be used.

Q3: What handling precautions are required?

Avoid dropping, impact, lateral bending and excessive clamping force. Ensure correct alignment and uniform blade pressure during installation. Cleaning methods must be compatible with both the zirconia blade and the processed material.

Q4: Can TecCera customize the dimensions and edge profile?

Yes. TecCera can evaluate custom lengths, widths, thicknesses, mounting features and edge profiles according to drawings. Achievable tolerances depend on component size, geometry and manufacturing requirements.
