The various types and sizes of Piston Rings are required to be cleaned as part of manufacturing process to create desired surface roughness for subsequent coating operations. The task of blast cleaning is performed either by dry blast cleaning or wet blast cleaning process.
The piston rings I.D./ O/D. are cleaned by propelling high-speed abrasive media on the surface with the help of compressed air. As a result, the contaminants/scales/rust etc. is removed and nascent metal is exposed on the surface. The selection of abrasive depends upon surface roughness required. However, use of finer size of aluminium oxide grit and glass beads (minute spherical glass balls) as abrasive blasting media is quite common.
The equipment is Closed Type Cabinet along with Automatic Abrasive Recycling and featured with provision of motorized mandrel rotation and nozzle reciprocation through hydro-pneumatic arrangement with adjustable stroke facility with the help of limit switches.
The dust generated during blasting process is collected in Fabric Bag Type Dust Collector Housing or Paper Filter Element Cartridge Reverse jet Type Dust Collector in Dry Blasting Machines. However, provision of Water Wash Gun, Slurry Agitation, Water Separator System & Mist Collector are the standard features of this equipment.
