The past few weeks have been exceptional and filled with quite unexpected events. At Hydroline, we also have a great responsibility in making sure our employees are safe and reminding them about the necessary precautions during this time.

We need to protect the weakest ones in our society.

Hydraulic cylinder assembly

29.04.2020 | Hydroline

In this blog post we will explain the assembly process. At Hydroline, our professionals take care of the process and even though it sounds very simple when put to words, it actually requires careful concentration and expertise. Before the assembly process starts, every part is carefully washed and protected. The purity level of each part is inspected by a washer and an assembler. Washing results and washed parts are sampled daily and their cleanliness is checked in our own cleanliness laboratory. Our washing machines’ washing solution cleanliness along with washing chemistry are examined regularly. We also have an ultrasonic cleaner for small and sensitive parts.

Friction welding

08.11.2019 | Hydroline

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.
