How to make the hollow piston rod more resistant to corrosion?
Apr 02, 2018

Usually, when the hollow piston rod is made, the selected material is 45# mechanical carbon steel seamless pipe. The hollow piston rod is suitable for use, including all kinds of precision mechanical casing and liquid, piston rod for air pressure cylinder and mechanical shaft of civil engineering machinery.


The so-called hollow piston rod, which belongs to a connecting part that supports the work of the piston. It is generally used in cylinder and cylinder motion execution parts. In the application, it belongs to a moving part with frequent movement and high technical requirements. And the quality of its processing often directly affects the life and reliability of the whole product.


Because of this, the machining requirements for hollow piston rod are more strict. It is usually required to maintain the surface roughness between Ra0.4 and 0.8um. Strict requirements for coaxiality and wear resistance. The basic feature of the cylinder rod is the slender shaft processing, which is difficult to process. It has been a very test technique for the processing personnel.


For the users, we hope that the hollow piston rod has longer service life, so it is necessary to ensure its strong corrosion resistance. Therefore, in processing and manufacturing, we need to finish polishing before plating, and we should determine reasonable plating time according to various aspects, so as to ensure good electroplating effect.


In the process of electroplating, it is necessary to ensure that the working conditions of the plating bath should be controlled well, such as problems or deviations should be adjusted in time, and the shortage should be supplemented in time. After electroplating, it is necessary to check the quality of the electroplating of the hollow piston rod, and whether there is any problem.


After these measures, the corrosion resistance of the hollow piston rod can be further improved, which means that the service life of the hollow piston rod is increased, and the service life of the hollow piston rod is more handy.http://www.xhychromerod.com/
