Ultrasonic UCI Metal Universal Hardness Tester for Rotogravure Cylinders

Ultrasonic UCI Metal Universal Hardness Tester for Rotogravure Cylinders

Rotogravure cylinders is an important component in printing equipment, it can directly effect the quality of printing quality, In direct gravure printing, the ink is applied directly to the cylinder and from the cylinder it is transferred to the substrate.
Rotogravure cylinders inner metal rolls are engineered and constructed of double-shell forged steel or chilled iron to maintain a uniform roll-face temperature, with a profile variance within 2°F (1°C) while operating at up to 500° F (260° C). Metal rolls are available with many options, which include: Nickel or chrome plated, Release coated, Precision ground, Heated or cooled, Hardened (case or through), etc.



To determination copper respectively chrome hardness of rotogravure cylinders simply, fast and accurately, UCI Hardness tests in Vickers range of light weight have the advantage that they are supposed to be non-destructive as the lasting surface indentation is microscopically small.

Measuring is effected by Vickers penetration procedure by ultrasonic evaluation of the indentation (UCI process). Different instrument adjustments (calibration values, penetration times, tolerance thresholds) for various metals can be stored in the device (e. g. copper, chrome, steel, zinc). A transfer to PC via Bluetooth or USB interface for long-term storing is possible on a very easy way.

The measuring values and the current average value are shown simultaneously and judged (cross means poor value) on the display in Vickers hardness HV or converted to others hardness scales. Furthermore, the whole measurement-series (statistic results, single measurement values) can be displayed at a glance.


Highlighting Characteristics of SU-300M:

Dear Visitor:

Thanks a lot for you browse our official website: www.sinowon.com firstly.
We, Sinowon Innovation Metrology Manufacture Limited is one of China authorized hi-tech manufacturer of metrology instrument verified by ISO9001:2015, we are focusing to research, develop, manufacture and export the optical measurement instruments and hardness testing machines since year 2006. We have already delivered and installed more than 10,000pcs of instruments to more than 5000 customers in more than 60 countries and regions, more and more international famous manufacturers choose us as the qualified supplier of quality control machines, and our service engineers have already visited USA, Canada, Mexico, Germany, Holland, France, Poland, Hungary, Czech, Turkey, Korea, Malaysia, Thailand, Philippine, Viet Nam, Singapore, Austria, India to install our instruments at customers’ site.

In the past 12 years, we concentrate ourselves to manufacture the instrument of quality control and never change our business field. We improve the quality and accuracy every year, up to now, it is 1.4+L/200um about the accuracy of our AutoVision vision measuring machine and it is 0.5HRC about the accuracy our iRock Rockwell hardness tester. Because the high quality of ultrasonic hardness tester SU-300 family, the national standard organizations SAC/TC 183 had invited us to make China national standard, the new standard: GB/T34205-2017 and JJF14306-2013 make more customers choose this NDT method: UCI to control the hardness of products.

As a manufacturer of quality control instruments, it is very important on own quality control system. In order to supply the stable quality products, we spent a lot of time and investment for staff training and quality system establishment and improvement every year, we also invest a lot of money to equip the international brand new coordinate measuring machines, roughness testers, humidity and temperature chambers, laser machines, glass scales, gauges and blocks for our own quality control. At the same time, Sinowon has been verified by ISO9001 quality management organizations every year, and our products have been issued by CE certificate for European market and Ghost certificate for Russian market.

The industry 4.0 is coming, we have already been ready for the challenge. Your request of precision is our mission forever, and we will supply the timely and warm-heart support and service as usual.
Let us work together, success together.
Thanks a lot again
