Quality Process

Traceability of forgings from its Raw Material stage (Mill) to finished components delivered to our customer and beyond, is given utmost importance. The system of codification of every bar of raw material received from every supplier and stringent incoming inspection ensures conforming material alone are taken up for cutting & subsequent operations like forging, machining etc., Every customer order/ schedule for each product are identified vide a unique product identification number, traces each and every operation in its cycle of production. All the stages of production are controlled by pre-set process parameters as required and trained engineers, who ensure delivery of quality forgings to customer, verify product requirement. Metallurgical engineers and UT Qualified personnel add strength to the Quality assurance team.

Our well-equipped Quality Assurance department draws up quality plants for all forgings to ensure that each of forgings, meet our customer requirement. Testing facility available in-house lends support to meet the laid out quality plans.

The Ring Rolling process is forming seamless rings from pierced discs or thick-walled, ring-shaped blanks between rolls that control wall thickness, ring diameter, height and contour.

This process provides all the advantages of the forged products coupled with very high material saving.

The Ring Rolled products may be broadly classified according to the rolling route as follows:
