Sinowon Ultrasonic Hardness Tester: Revolutionary Non-Destructive Solution for High-Precision Measurement in Automotive Mold Industry

In automotive mold manufacturing, precise hardness measurement is critical for ensuring component performance and longevity. Traditional methods (Brinell, Rockwell) face challenges like large indentations, complex operations, and workpiece damage. Sinowon's ultrasonic hardness testers, featuring non-destructive testing (NDT) technology and high accuracy, are transforming quality control in the automotive mold sector.

Key Challenges in Automotive Mold Hardness Measurement

Automotive molds involve complex components (gears, crankshafts, stampings) with critical measurement challenges:

• Surface Damage Risks - Traditional indentation methods may compromise precision surfaces
• Measurement Limitations - Immovable large workpieces; hard-to-reach geometries (gear roots, shaft grooves)
• Efficiency vs Accuracy Dilemma - Lab testing delays vs production-line rapid sampling demands

Sinowon SU Series Technical Advantages

Our SU-300/SU-400 ultrasonic hardness testers use Ultrasonic Contact Impedance (UCI) method with:

• Zero Visible Damage - Microscopic indentations protect high-value molds
• 360° Omnidirectional Testing - Measure gears, bores, and complex geometries at any angle
• Rapid Precision - ±1.5HRC accuracy with 1-second results for full inspections
• 7-Scale Smart Conversion - HV/HB/HRC compatibility for steel, alloys, and multi-layer materials

Automotive Mold Applications & Case Studies

1. Surface Hardened Layer Inspection

• Directly measure carburized/nitrided gear mold hardness gradients without destructive cross-sectioning.
• Result: Eliminated 80% sample destruction in gear batch testing

2. Weld Zone Evaluation

• Assess hardness uniformity in repaired molds without disassembly.
• Case: Detected 15% hardness drop in crankshaft weld HAZ, preventing premature failure

3. Micro Stamping QA

SU-300's ultra-light probe (1kg test force) ensures damage-free thin sheet measurements.
Application: 0.5mm automotive shim production QC

4. Large Mold Monitoring

Portable design with Bluetooth® data logging enables shop-floor hardness mapping.
Benefit: 50% faster mold wear trend analysis via included SinowonTrend software
