Mixture: As per mix design process, bajri (coarse aggregates), water & Cement are used by weight. Instructions are written on boards for proper mixtures. Instructions are given to consume mixture within 30 minutes for its proper strength.


Moulding: All moulds are properly cleaned from Hand Grinder after opening. Proper supports are given for centring of cages. {If it is higher dia 2 cages are made as per IS: 458 & upper cage is always 75% of inner cage} Proper oiling is done on moulds as well as on bushes & rings. These are properly packed with tie rods & nut-bolts.


Manufacturing: After molding moulds are properly kept on runners with the help of Chain Pulleys. Initially while pouring the mixture RPM of machine is very slow for proper pouring & then RPM are up to 1500 as per the requirement of IS: 458. When the proper spinning is done it leaves extra water which gives the strength to the pipe. After it, finishing of pipes is done by cutting from rods & brushes.


Demolding: While demolding, with the help of Chain pulleys moulds are separated. Moulds are separated after 24 hours for proper quality of pipes.


Curing: After Remoulding with the help of Trolleys, Hydra & ceilings pipes are kept in curing tanks for proper curing. Rotation of pipes is done daily & 24 hours Sprinklers are on. After 28 days curing pipes are taken out from tanks & storage is done.
