Making Product Best

Quality assurance activities for the Every product of our plant are closely Co ordinated at following stage.

raw-materiL
Raw Material

♦We Follow Our Standard Procedure For Every Material Which We Procured From Steel Suppliers. First We Do Metallurgical Testing Like Chemical Test , Macro Inclusion , UT Of Rolled Round Bar Procured From Suppliers. All Testing Held By In-House  / NABL approved  Laboratory .

♦Round Bar Are Identified By Color Code On Both End Of The Bar. We Always Purchase Material Form Oems Approved Source Like ISMT , JSW , Gardau , Bhushan Power & Steel , Jayswal Neco , VSP Etc.

Die Manufacturing & Inspection

♦ All Types Of Die Like Trimming Die-punch , Cup Forming Die-punch, Die For Forging Done In-house Die Shop it include VMC & Conventional Leth .

♦Using Dies material DIN-2714 for Closed die forging & H11/H13 for press forging. and Ring Rolling .  Hardness: 38-42 HRC

♦Finished Impression of Die is 100% dimensionally checked by LAYOUT INSPECTION on Plaster of Paris (POP) mould.

IN-HOUSE RAW MATERIAL TESTING

♦ Chemical Analysis is done by Spectrometer. Make: GNR ITALY

♦Other testing facility available like Micro cleanliness, Hardness,

♦Metallurgical Microscope with image Analyzer software available to check Micro structure, Grain size after Annealing or Normalizing.

BLANK CUTTING

♦ Cut blanks are done on high productive precise circular saw machine with auto loader facility & band saw.

♦We also have facility of hot shearing machine which attach in long bar induction in that Dedicated For SAE52100 material

Heating

♦ Cut blanks are heated by Induction billet heater with Controlled Temperature for Hammer forging & Press Forging. Continuous Type Oil fire Furness For Ring Rolling Forging  

♦ Long bar heater for Ring Rolling Forging with addition facility of billet heating

♦ Induction billet Heater with accepter/rejecter facility which segregate low heated / over heated material and controlled heated material only going for process    

 

Forging

♦ Forgings operations are performed with hammers & presses includes bending, drawing down, upsetting, rolling and finish product . Subsequent Trimming operation to remove excess material is done on Power Press

♦Forgings operations are performed with presses & Ring-rolling includes upsetting, Cup Forming, Piercing , rolling which execute in one heating cycle to gather with finish forging.

In House Heat Treatment

♦ After Forging Completed Forging Components Undergoes Required Process Of Normalizing Or Sherardized Annealing As Per Validate Temperature & Time Cycle.

♦This operation performed in house with bell type induction Furness with Facility of Real time tracking  i-Tool Software 

♦Micro Structure Testing Of Sherardized Annealed Or Normalized Components As Per Quality Plan.

♦Quenched–Tempered process held by out source which is reputed and approved from OEMs and our customers 

 

Shot blasting & fettling

♦ Forging surface De-scaling operation is done by Tumbler type shot blasting machine.

♦Using proper grade of shots ( 0.45 & 0.55 mm) to avoid pit marks.

♦100% fettling is done for flash projection, burr, chopping etc

Quality Inspection – Hardeness & Crack Detection

♦ Visual inspection is carried out after shot blasting. PDI (pre dispatch inspection report) is done & sent along with material to the customers.

♦Brinell hardness tester for 3000kg load & 10mm dia is used for hardness checking.

♦Magnetic partical TEST (MPI) is done for all functionally critical forging as customer’s requirement.
