FAQ

. Quotation & Specifications

1. What specifications are required for a quotation request?
   To provide an accurate quote, please share:
   • Material Type: Paper (kraft, corrugated), film (BOPP, PET, PVC), or non-woven fabrics.
   • Blade Parameters: Outer diameter (50-600mm), bore size, thickness tolerance (±0.002mm), tooth geometry (e.g., T-shape for film).
   • Technical Requirements: Cutting speed (RPM), daily output capacity (tons), and surface roughness needs (e.g., Ra ≤0.4μm) .
   • Certification: ISO 9001 is standard; specify if additional certifications (e.g., JB/T) are needed .

. Brand & Manufacturing

1. Is Shengao a manufacturer or trading company?
   Shengao is an ISO 9001-certified manufacturer with in-house R&D and precision grinding facilities. Our blades undergo:
   • Vacuum Heat Treatment: Hardness up to HRA 93.5-95 (exceeding industry average) .
   • CNC Grinding: Tolerance control at ±0.002mm for edge sharpness .
   • Quality Control: 100% hardness testing + AQL sampling per ASTM B890-07 standards .

. Applications & Performance

1. What materials and machines are these blades compatible with?

   • Materials: Optimized for paper rolls (≤1200 gsm), polymer films (0.1-1.0mm), and non-woven fabrics .
   • Machines: Automatic slitting machines, rotary cutters, and high-speed guillotines .
   • Performance:
     • Cutting speed: 20-50 m/min for films, 10-30 m/min for thick papers .
     • Lifespan: 3-5x longer vs. HSS blades due to tungsten carbide's wear resistance .

2. How do Shengao blades ensure cutting quality?

   • Tooth Design: Laser-cut TCT (Tungsten Carbide Tipped) teeth reduce burrs on film edges .
   • Cooling Technology: Integrated lubrication grooves prevent overheating (critical for BOPP films) .
   • Surface Finish: Grinding precision ensures Ra ≤0.4μm for smooth cuts .

. Customization & Solutions

1. Do you support non-standard blade customization?
   Yes. Shengao offers:
   • Size Customization: Diameters <50mm or >600mm (e.g., φ30mm for narrow-film slitters).
   • Material Upgrades: Tungsten carbide grades (e.g., YG12X for abrasive materials) .
   • Coating Options: TiAlN coating for high-heat environments (e.g., PET film cutting) .
     Submit technical drawings for expedited solutions.

. Quality Assurance

1. How does ISO 9001 certification guarantee blade reliability?
   Our certification mandates:
   • Raw Material Control: WC powder purity ≥99.95% (traceable to suppliers) .
   • Process Rigor: XRF spectrometry for tungsten content validation (RSD ≤0.2) .
   • Warranty: 12-month coverage against manufacturing defects.

. Technical Support

1. What after-sales services do you provide?
   • Blade Regrinding: Extends lifespan by 200% (3-5 regrinds per blade) .
   • Setup Guidance: Optimization manuals for RPM/cutting pressure based on material density.
   • Emergency Replacement: 72-hour delivery for standard blades (OD 50-600mm).
