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.

As a core component of engines, crankshaft hardness directly determines wear resistance, fatigue strength, and overall performance. Traditional destructive testing methods struggle to meet modern efficiency demands. Sinowon's ultrasonic hardness testers, featuring non-destructive measurement, high precision (±3% HV/±1.5HRC), and portable design, emerge as the optimal solution for crankshaft quality control.

In heat treatment processes, hardness is a critical indicator of material performance, directly impacting wear resistance, strength, and service life. Traditional hardness measurement methods often face limitations due to large indentations, complex operations, or workpiece damage. Sinowon's self-developed ultrasonic hardness tester, featuring non-destructive testing, high precision, portability, and broad applicability, has become the ideal tool for hardness detection in the heat treatment industry.

In the gear manufacturing sector, hardness is a critical indicator of material performance. Traditional methods like Rockwell and Brinell testing often face limitations due to visible indentations, complex operations, or incompatibility with complex workpiece geometries. Sinowon Instruments' ultrasonic hardness meter series (SU-100, SU-300, SU-400), based on Ultrasonic Contact Impedance (UCI) technology, offers a non-destructive, high-precision solution, setting new benchmarks in industrial inspection.

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.

In industrial manufacturing and quality inspection, material hardness remains a critical indicator of mechanical performance. As China's leading testing equipment provider, Sinowon introduces its SU Series Ultrasonic Hardness Testers utilizing Ultrasonic Contact Impedance (UCI) technology. Designed for non-destructive testing, high accuracy, and portability, our solutions serve aerospace, automotive, energy, and metalworking industries with unmatched efficiency.

Firstly, it must be known what material is tested, please check the typical application in the following table, it will be helpful to choose right probe. If there is coating or plating on the specimen, it is better to choose the motorzied probe with minimum testing force, but you must consider the roughenss of suface. If the roughness is high, the light force probe is not suitable.
Secondly, if the speimen is small and massive, it is better to choose a stationary stand to make the testing relia
