SHEET METAL FORMING

Sheet Forming

Sheet Metal Products Sheet metal workshop for JF-17 parts houses an array of conventional and CNC machining facility. Machines such as Guillotine and Nibbling Shear, Conventional and CNC Stack Routers etc are utilized for processes like Shearing, Routing and Sawing techniques. Whereas CNC shot peen forming, Hydraulic Quintus Fluid Cell press, CNC Stretch Forming and CNC punching etc are used for manufacturing of parts involving sheet forming processes.
  • Bending of aluminium sheet up to 4 mm with 03 axis machine
  • Shrinking, Doming, Planishing and Straightening process
  • Reforming, Flattening and Stretching process
