SERIOUS INDUSTRIAL SECTORS
ENGINEERED FOR DEMANDING APPLICATIONS
STRATEGIC SECTOR
DEFENCE MANUFACTURING
Tank components, pistons, pinions, and critical military assemblies engineered to stringent defence standards with complete heat-number batch traceability.
INFRASTRUCTURE
RAILWAY COMPONENTS
Braking systems, bogie hardware, eye bolt links, draw gear, and engine components built for high dynamic fatigue resistance.
HEAVY ENGINEERING & OEM
HEAVY & AUTOMOTIVE INDUSTRY
Alloy steel rounds, gear blanks, flanges, rolled rings, and custom machined components for heavy machinery and commercial vehicles.
END-TO-END CAPABILITY
ONE COMPONENT.
ONE CONTROLLED MANUFACTURING CHAIN.
From induction melting raw scrap steel to final lab testing and heat-number certification, every process remains strictly inside our Ludhiana facilities.
02
PROCESS STEP
ROLL — Alloy Steel Rolling
Billets are hot-rolled into alloy steel rounds and bars in exact dimensions required for forging dies and customer drawings.
03
PROCESS STEP
FORGE — Precision Drop Forging
Drop hammers and forging presses form components hot, establishing continuous grain flow for superior tensile strength over cast parts.
04
PROCESS STEP
TREAT — Controlled Heat Treatment
Normalizing, hardening, and tempering furnaces bring the component to exact mechanical properties, grain structure, and HBW/HRC hardness.
05
PROCESS STEP
MACHINE — CNC / VMC Machining
Turning centers and 3-axis/4-axis vertical machining centers machine forgings to micron-level drawing tolerances and specified micro-finish.
06
PROCESS STEP
PROVE — Testing & Inspection Lab
Spectrometer analysis, UTM tensile testing, hardness testing, MPI crack detection, and Izod impact proving before batch certification.
OUR MANUFACTURING PHILOSOPHY
WE DON'T JUST SELL COMPONENTS. WE CONTROL THE ENGINEERING AND MANUFACTURING PROCESS THAT CREATES THEM. ONE INTEGRATED PLANT TAKES SCRAP METAL TO FINISHED GOODS: MELTED, ROLLED, FORGED, HEAT TREATED, MACHINED AND PROVEN IN OUR CERTIFIED LAB BEFORE IT SHIPS.
