The piston ring is a metal ring used to be embedded in the piston groove. There are two types of piston rings: compression ring and oil ring. It has four main functions: sealing, adjusting oil (oil control), conducting heat (heat transfer), and guiding (support). There are two main materials: cast iron and steel.

Piston rings are widely used in various power machinery, such as steam engines, diesel engines, gasoline engines, compressors, hydraulic engines, etc. With the development of society, there are more and more types of piston ring specifications. How to distinguish, identify and manage such complex and diverse piston rings requires identifying information on their surface marks. And the national standard GB/T 1149.1-94 stipulates that the name, form, size, code, material code, and corresponding national standard number must be clearly marked on the piston ring.

The traditional marking method has many processes, high consumables, insufficient marking, and long production cycle. In addition, some marking methods can also cause internal stress and deformation of the piston ring. The laser marking machine came into being and easily solved the shortcomings of the traditional marking method. However, the standard laser marking machine does not have the functions of positioning, automatic identification, automatic material transfer, etc., and the workpiece must be placed in the laser for each piston ring processed. The marking machine specifies the position for processing, and after the processing is completed, it is taken away. The positioning, feeding, and unloading are all realized manually, which is low in automation and low efficiency. It not only causes inconvenience to work, but also affects work efficiency. According to market needs, Foshan Fulan Laser Technology Co., Ltd. has specially developed a dedicated automatic laser marking machine for piston rings.

Next, the editor will introduce to you the piston ring automatic laser marking machine independently developed and produced by Foshan Fulan Laser Technology Co., Ltd.:
