Toroidal Cores ProcessWe manufacture CRGO and CRNGO lamination material using strips wound core process. This is a specialized process that requires high degree of precision. Further, it also allows cores to be manufactured from selected coils of CRGO electrical steel so as to yield closely controlled electro-magnetic characteristics as well as dimensional accuracy. Working Process: - Cores are wound after slitting is done as per required shapes on core winding machines
- Winding machine automatically stops when pre-decided dimension is reached
- The start and finish ends are firmly spot welded
- After winding, cores are stress-relief annealed so as to restore magnetic properties
- These cores are bonded where necessary so as to provide increased firmness
- All cores are spray painted and are tested for magnetic properties
- Strip wound cores, unlike strip lamination, constitute complete product and every core must meet specified performance requirements (Consequently, quality control in the manufacturing of wound cores is vitally important at every stage of process)

Transformer LaminationWe offer customers Transformer Lamination Products. These meet the demands of manufacturing power and distribution transformers from various grades of CRGO steel. As transformer lamination has to be done according to different specifications given by customers, whole process is carried out in one section itself so as to achieve better flexibility & control. Process:
- Lamination in various shades & sizes are slit and are cut in required accurate geometrical shapes with 90 degree and 45 degree cutting systems
- Different machinery is used throughout the process
- Slitting machine is used to slit CRGO (In this process minimizing burrs is very important aspect, thus shearing angle is checked for achieving perfect match at edges during initial setting)
- After this, material are hole punched and ‘v’ notched using power press
- For achieving accuracy, tungsten carbide tipped tools are also utilized for performing ‘v’ notching operations
- Now at this point of time, material develops residual stresses because of sensitivity (For eliminating such stresses, laminations are taken to roller hearth annealing furnace where the processing prevents any probable distortion, shortens cycle time as well as ensures that insulation is sustained even at high temperatures)
- At end, processed material are brought into inspection department where these are thoroughly checked for technical details and its dimensions by QC professionals and then forwarded to packing department
- In packaging department, finished products are packed in wooden pallets according to its size & full description of material including technical details is attached with the pallet
- Thereafter it is dispatched to the respective clients
