Sinowon Ultrasonic Hardness Tester in Printing Roller Industry

In the printing plate-making industry, rollers serve as critical precision components where coating hardness directly determines print quality and equipment lifespan. Traditional portable hardness testers like Leeb devices face limitations in accurately measuring microhardness of copper/chrome coatings and often leave visible indentations. Sinowon's SU-320R Ultrasonic Hardness Tester breaks through these industry barriers with innovative technology, redefining precision standards for roller hardness measurement.

Industry Challenges & Technological Breakthroughs
Traditional methods struggle with:
✓ Thin coatings (50-200μm) vulnerable to substrate penetration
✓ Zero-tolerance for surface damage on high-value rollers
✓ Measurement inaccuracies from coating anisotropy

SU-320R's Ultrasonic Contact Impedance (UCI) method with patented MP-200 micro-force probe delivers:
✓ Ultra-low 2N test force
✓ Microscopic indentation (invisible to naked eye)
✓ Multi-directional testing (vertical/horizontal/curved surfaces)
✓ 60% improvement in true coating hardness detection

Technical Advantages
✓ Non-Destructive Testing
MP-200's diamond pyramid indenter (136° angle) creates sub-microscopic marks - smaller than conventional microhardness testers. Ensures surface integrity for premium rollers.

✓ Lightning-Fast Measurement
2-second results (60x faster than benchtop units) boost production efficiency and reduce costs.

✓ Smart Data Management
1,000-data storage capacity with 20 calibration profiles enables traceability and eliminates repetitive calibration.

✓ Advanced Compensation System
Auto-correction for Young's modulus variations (Cu/Cr/Ni coatings) and thermal compensation (-10℃~50℃) ensure ±0.5HRC accuracy.

✓ Industrial-Grade Design
IP54 dustproof housing, magnetic probe interface (3s replacement), and 3.2" color touchscreen with hardness distribution heatmaps.

Key Applications
• Chrome-plated rollers: Precise 700-1100HV0.3 measurement (1HV resolution)
• Engraved copper layers: Hardness gradient analysis
• Repair verification: Non-destructive weld zone inspection
• Process control: Hardness-wear resistance-printing cycles modeling
