Innovative Application of Sinowon Ultrasonic Hardness Testers in On-Site Corrugated Roller Hardness Measurement

In the manufacturing and maintenance of corrugated rollers, surface hardness is a critical indicator of wear resistance, service life, and print quality. Traditional hardness testing methods often require destructive sampling or laboratory equipment, leading to inefficiency and workpiece damage. Sinowon’s ultrasonic hardness tester series (e.g., SU-300H, SU-300M) delivers a non-destructive, high-precision, and portable solution for on-site corrugated roller hardness measurement, setting a new industry benchmark.

Challenges in Corrugated Roller Hardness Measurement

Corrugated rollers undergo surface treatments like chrome plating and carburizing, requiring uniform hardness distribution across the roller and tooth roots. Traditional methods face limitations:

• Destructive sampling with micro-hardness testers.
• Low accuracy and visibility issues with portable Leeb hardness testers.
• Complex geometries and large sizes demand non-destructive, rapid, and traceable on-site testing.

Core Advantages of Sinowon Ultrasonic Hardness Testers

1. Non-Destructive Testing Technology

Using the Ultrasonic Contact Impedance (UCI) method, Sinowon testers measure hardness through resonant frequency shifts, leaving micro-indentations visible only under high-magnification microscopes. Ideal for chrome-plated surfaces with zero damage.

2. High Accuracy & Multi-Scale Compatibility

• Supports HV, HRC/HRB/HRA, HB scales.
• Accuracy: ±3% HV / ±1.5 HR.
• Covers common hardness ranges: HV100-1500, HRC20-68.

3. Portability & Smart Features

• 2-6 seconds per measurement (20-60x faster than lab equipment).
• 3.2-inch color screen displays real-time stats (max/min/avg) in multiple languages.
• Bluetooth connectivity for wireless data export (supports 2,000 datasets).

4. Rugged Design for Harsh Environments

• Aluminum alloy housing + scratch-resistant glass.
• Operates in -10°C to 50°C and 30-80% humidity – perfect for humid print shops.

On-Site Applications & Case Studies

Case 1: Chrome Coating Uniformity Testing

Sinowon SU-300H with 3N motorized probes ensures precise hardness mapping, preventing premature wear from uneven coatings.

Case 2: Tooth Root & Complex Geometry Measurement

Custom probes (10N manual or MP motorized) enable multi-angle access to grooves and hard-to-reach areas.

Case 3: Production Line Integration

SU-300 integrates with robotic arms for real-time monitoring in heat treatment or machining lines, boosting QC efficiency.
