MANUFACTURING Process
MELTING
Input : Charging of Virgin material and clean process scrap
Output : Will produce 7” & 9” logs which are cut into billets of required length
EXTRUSION
Depending on requirement of tube size billet is cut into its length Billet Pre Heating temp 650-780 ͦc.
Will extrude the tube keeping dimensions with in the tolerance and discard the back end 250-300mm of extruded tube in hot condition and Front end is cut after cooling of 150-200mm
Process Name: Reeling
Reeling is operation to make the straightness of the tube. Tube is inserted in between conical rollers which moves in anti-clockwise direction and tube moves in clock wise direction.
Process Name: Annealing
Annealing operation is done to relieve internal stress which are develop in the extrusion process and also to maintain mechanical properties in material.
Process Name: CNC
In CNC M/C will set program will do machining OD & ID and maintain the dimensions tolerances as per the requirement.
After Ring cutting from tube in CNC, will transfer the rings into Vibratory finishing M/C for removal bur from Rings.
Process Name: Quality Inspection
As per tolerance specified for Synchronize Ring size will check Go no gauge for OD & Width. Accepted & rejection will done after checking of ring
100% Visual & dimensions inspection of ring as per specifications tolerance. Confirm Accepted or rejected of ring and enter into the Inspection record
Process Name: Packing & Dispatch
Each Box is identified with Size, Heat No, Alloy, Quantity, Weight & Material Code. Its verified by dispatch team.
