SINFT Raw Material Assurance System

Every raw material and finished product undergoes rigorous multi-stage quality verification throughout the production process.

Digital Microscope — 2D/3D Analysis

Digital Microscope — Metallographic & 2D/3D Analysis

SINFT uses advanced digital microscopes throughout the production process to verify material quality, welding integrity, and interlayer bonding.

Material composition verification at incoming inspection
Metallographic analysis of sintered mesh bonding quality
Cut edge precision and surface defect detection
Calendering and leveling surface flatness inspection

2D/3D Imaging Metallographic Analysis Non-Destructive Testing

Air Flow Tester & Pore Size Analyzer

Every finished sintered mesh product is tested for filtration performance — air permeability, bubble point, and pore size distribution per ISO international standards.

Air permeability and flow rate curves — custom curves available
Bubble point integrity test per ASTM F316
Pore size determination per ISO 4003
Filtration precision verified before shipment

Air Flow Test Bubble Point Test ISO 4003 Standard

Quality Verification — Test Reports

Third-Party Test Reports

SINFT supports providing factory test reports, filtration accuracy test reports, pressure resistance test reports and third-party inspection documents for hydraulic filters — meeting industrial equipment customers' needs for quality verification and supply chain audits.

Production — ISO Class 8 Cleanroom

ISO Class 8 Cleanroom

High-precision hydraulic systems have extremely high requirements for initial cleanliness of filter elements. SINFT uses ISO Class 8 cleanrooms for high-precision hydraulic filter production and assembly — effectively reducing fiber shedding, dust and metal particle contamination risks.

Clean production environment helps hydraulic systems reduce pollutant circulation and improve equipment operation stability and filter service life.

ISO Class 8 certified
Low fiber shedding
Reduced particulate contamination
