Gravimetric analysis in hydraulic cylinder manufacturing
01.06.2020 | hydroline
Cleanliness can be monitored and measured with many different ways and in this text, we will be telling you about our gravimetric analysis: the analysis is a method used in analytical chemistry for quantitative determination of an analyte based on its mass. To put simply; our expert compares a clean membrane mass to a membrane that has been used for filtering the washing liquid. Any particles and mass that are found are photographed, measured and documented into a report. At Hydroline, the gravimetric analysis is conducted to randomly selected parts and components.

In friction welding, two components are rubber together at a controlled rotational speed. Although the term welding is used to define the process, it actually has no resemblance to conventional welding as there is not filler material involved. The other component stays on place and the other one is rotated as the components are brought together. When pressing the components together, this creates the fiction and the heat that allows both components to reach a plastic state and be forged together. Rotation is stopped and after that, some extra pressure is applied to the joint. With friction welding, a 100% welded, forged quality bond is achieved. As a final step, the machine removes the extra flash by lathing.
Fully automated production line - the future of hydraulic cylinder manufacturing
21.10.2019 | hydroline
The project kicked off already in 2017 when Hydroline received a significant funding for growth and capacity increase in both factories. The market prospects showed extremely positive forecasts and Hydroline needed to make big steps towards international growth. The project for the automated line really kicked off in the beginning of 2018 when the careful design, calculations and simulations were implemented, soon after that we ordered the key machines – robot systems etc. – for the line.
