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.

Over four decades of evolution, image measurement technology has transitioned from laboratories to industrial settings. Manufacturers like Sinowon have achieved sub-micron precision through continuous innovation, transforming China from a technology follower to a global innovator in the industry. Today, advancements such as AI-enhanced software algorithms, non-contact high-ratio optical zoom lenses, multi-field-of-view telecentric lenses, point-spectrum probes, 3D line-scan cameras, and fourth-axis electric rotary stages are converging on image measurement platforms. These integrations have elevated image measurement systems into indispensable industrial inspection tools, delivering increasingly powerful capabilities for modern manufacturing.

There are 5 series of manual and semi-automatic type among Sinowon vision measuring machine, it is iMove, iVision, iFocus, iTouch and iSemi.

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

1.What is warranty time for Sinowon products exported to international market?
Answer: in China, we supply 12-month as warranty time for the customers, the date time is started to count from the machine installed and acceptance checked. As for instruments exported to international market, it is 15-month for warranty time, but it is started to count from the shipping time, the shipping time will be declared and found on the bill of loading or airways.

What is the reason the customers prefer to buy the autofocus vision microscope VM-500?

This is the equation about how to compute the optical magnification and vision magnification for the optical microscopes and digital microscopes.
