3. Piston ring is one of the most important part of the
Diesel/Petrol engines. It is an open-ended
ring that fits into a groove on the outer diameter of a
piston in a reciprocating engine such as an
internal combustion engine or steam engine. The
principal function of the piston rings is to form
a seal between the combustion chamber and the
crankcase of the engine. The goal is to prevent
combustion gases from passing into the crankcase
and oil from passing into the combustion chamber.

5. Piston ring is the one of the most replaceable part of the diesel/petrol
engines. It has great demand in the replaceable market as well as in new
engines market. For the last few years there is noticeable increase in the
automobile industry, which is the vast market for it. Piston rings are not
only used in the automobile industry but also used in :
Railway Engines
Compressors
Steam Hammers
Cars
So, by maintaining quality and using proper marketing
techniques there is always a great market of this product.

10. The materials used to make Piston Rings are one of the
most critical factors in its performance.
Listed below are some of today's common material
used in manufacturing of piston rings and metallic
seals:
Cast iron , Cast iron alloyed for piston rings ,
Nodular cast iron alloyed for piston rings.

12. The blanks of cast rings of required size and desired
properties are procured from the foundries. After that
blanks are cleaned and get ground .Then the blanks are
undergone through various processes like facing, rough
diameter , rough bore, finish diameter & finish bore. The
rings are generally machined to the required shape by
means of turning, a process in which the ring blank,
already axially ground, is copy turned on the inside and
outside diameters. After a segment equivalent to the free
gap is cut from the ring it assumes the free shape that will
give it the required radial pressure distribution when
fitted into the cylinder.

16. The procured blanks castings should be
checked very carefully as per given
requirement(size , grade etc).This is the very
first step in quality control . The product
should be monitored after completion of each
stage so that chance of rejection at the end is
eliminated.
Piston rings should be manufactured as per
IS : 5791 -1971 & IS: 8422 for IC engines.
