Optical axis - observe and see that most of the surface of the piston rod has a chromium plating layer.

The electroplating treatment of piston rod is not simple, but also requires a higher technical content, it is necessary to remind everyone about this. In the piston rod electroplating, we must control the working conditions of the bath, and always pay attention to its temperature and level changes. At the same time, we should regularly add the potion according to the observation results, so as to achieve the purpose of correcting the plating solution. Optic axis
The gas pressure and inertial force acting on the piston vary periodically, so the gas pressure acting on the piston instantaneously is very high. Moreover, the piston must be subjected to the periodic impact of the lateral pressure at the inclined position of the connecting rod. Under the combined action of gas pressure, reciprocating inertial force and lateral pressure, the piston may be activated. Plug deformation, piston pin seat cracking, piston side wear and other defects.
The piston rod is made of alloy structural steel with excellent properties. In order to ensure the smooth cutting of the tool, the tool material must also be alloy structural steel. Not only that, but also the proper surface treatment, nitriding treatment is one of the more effective ways.
