  1. AC/DC motor laminations in standard IEC 63F to IEC 355F with stacked stators and Aluminum die cast rotors, Fans, Generators, Pump motors, Alternators, Automotive – EV / HEV, Aviation, Servo motors and many more. We offer self-bonding laminations especially for automotive industry. We also punch CR and HR end laminations up to 2 mm thickness, over and above 2 mm it is either laser cut or water jet. 
  2. Strips/EI laminations as per customers requirements and DIN standards. CNC cut-to-length lines to process all grades of CRNGO as rectangular strip laminations with multiple hole options.

  • Our focus is on processing higher grades for energy efficient products along with conventional grades in thicknesses 0.20/0.35/0.50/0.65 mm. Prime Electrical steel is sourced directly from CSC - Taiwan and India, TKES - India, SAIL – India, JSW Steel - India, Tata Steel – India, Cogent - UK. 
  • Value addition to the laminations through our associates are: -  Machining of stators and rotors, Winding of stators, Shaft insertion in rotors, Aluminum / Cast Iron motor body, Copper die cast rotors, Laser cutting for prototypes.
  • Our state-of-art manufacturing facilities spread over 10,000 m² of built-up area houses modern –

  1. High speed / gang punching presses from 32 T up to 400 T 
  2. Vertical die casting m/c from 75 T up to 250 T, broaching for rotor ID 
  3. Notching / indexing up to 1200 mm diameters 
  4. Auto cleating / auto welding machines 
  5. Slitting lines to accommodate coil weight up to 20 MT and width up to 1300 mm
  6. BAB (Burning / Annealing / Bluing) type continuous furnace capable to process 500 M.T. of laminations/month along with host of supporting equipment’s. 

  • Our modern testing and inspection facilities incorporates Epstein test frame, Franklin tester, Rotor analyzer, Stator core tester, Optical CMM and more.
  • We are ISO 9001:2015 and ISO/TS 16949:2008 certified company. Our capacity to punch 2000 MT/month of finished laminations will surely meet your demanding parameters.
